Swarm Technologies, Inc. is a company building a low Earth orbit satellite constellation for communications with Internet of Things (IoT) devices using a store and forward design. Social Capital partners Jay Zaveri and Arjun Sethi incubated and seed funded Swarm, Craft Ventures was an early investor. On 16 July 2021, Swarm agreed to become a wholly owned subsidiary of SpaceX.[2]

Key Information

In-Q-Tel, the venture capital arm of the CIA, lists Swarm Technologies as one of their startups.[3]

They have a Federal Communications Commission (FCC) licence for low bandwidth communications satellites in low Earth orbit.[4]

In 2018, Swarm became the first U.S. company found to have deployed satellites without regulatory approval after an FCC investigation into the startup's launch of its first four picosatellites on an Indian PSLV rocket in January of that year.[5]

In 2019, Swarm raised $25 million in a Series A funding round led by EarthLink founder Sky Dayton and PayPal co-founder David Sacks.[6]

The Swarm Tile is its dedicated two-way satellite data modem designed to be low energy and embedded on the PCB of third-party products. Other products include a data plan and a development kit.[7]

In July 2023, the company stopped new device sales.[8]

In March 2025, the service was stopped. The company's URL (swarm.space) now forwards to SpaceX' direct to device infopage.[9]

History

[edit]

Swarm Technologies was founded in 2016 by Sara Spangelo and Benjamin Longmier, former employees of Google and Apple, respectively.[10]

The company became widely known in industry circles after launching its first four test satellites illegally in 2018. The responsible US regulatory authority, FCC, had refused the license for the start-up because they feared that the satellites could be too small to be recognized by the space surveillance systems. They could become particularly dangerous, turning into "invisible" space debris. Despite this, the satellites, and around 30 other payloads were launched on an Indian PSLV rocket.[10] The FCC imposed a $900,000 fine for this.[11] The housing of the next test satellites was then enlarged. Together with correspondingly enlarged radar reflectors and a GPS-based position transmitter, the increased traceability permitted licensing to be achieved.[12][13][14]

The construction of the actual constellation began with the launch of twelve third-generation SpaceBEEs on September 3, 2020, on a European Vega rocket. After an additional 48 SpaceBEE satellites were launched by the end of January 2021, commercial operations of the constellation began.[15]

By December 2020, Swarm had launched 9 test satellites and 36 of a planned 150 low Earth orbit satellites to provide communication with IOT devices.[16]

In February 2021, Swarm announced that its commercial services were now live using 72 commercial satellites providing its global low-cost data service to customers.[17]

In July 2021, SpaceX acquired Swarm for $524 million.[2][18]

In July 2023, the company stopped new device sales.[8] As of November 2024, the website of the company redirects to SpaceX's upcoming direct-to-cell feature.

On 27th September 2024, existing customers were advised the following. "Based on our most recent simulations and modeling, we regret to inform you that service and support for the Swarm commercial network will cease 90 days from today, and your data service plans with Swarm will terminate as of such date."

Technology and use

[edit]

The third-generation SpaceBEE satellites weigh around 400 grams and, like the first generation, have a 0.25U CubeSat format; according to the manufacturer, they are about 11 × 11 × 2.8 centimeters in size.[19] The second generation is 1U cubesats. Solar cells for the power supply are located on the top and the bottom. The antenna for communication with the ground stations is wrapped around the satellite when launched and unfolds after the release into space. The data exchange is performed in a relatively small bandwidth, on the one hand with the end devices and on the other with ground stations connected to the Internet. After the constellation is completed, at least three satellites should always be reachable from any point on earth.

Swarm Technologies in 2020 offered data transfer plans starting at $60 per year per connected device. At this price, 750 data packets of 192 bytes each can be transmitted monthly.[20]

2018 controversy and fine

[edit]

As a US corporation, Swarm has to follow US space regulatory procedures. In April 2017, Swarm applied for FCC permission to obtain an experimental radio service license for its initial picosatellites. The FCC rejected the application in December 2017 due to concerns about tracking because of the tiny size of the satellites (measuring 0.25U CubeSat size), but they were launched from India the following month.[21][22]

After the launch was reported, an authorized April 2018 launch of more satellites was immediately delayed when FCC permission was withdrawn. An FCC investigation found that Swarm had not only launched the four unauthorized satellites but also unlawfully transmitted signals between them and earth stations in Georgia. The investigation also discovered that Swarm had performed various other equipment tests before the launch without required FCC authorizations, including between weather balloons and ground stations.[23]

Industry reaction was also highly negative, fearing disruption from uncoordinated activity and enhanced future regulation.[24] Spaceflight Inc., which had arranged the Indian launch as a rideshare, changed its processes to check that customers have the proper licenses.[25]

The settlement required Swarm to pay a penalty of $900,000 and to follow a strict compliance plan to prevent future violations. This included submitting additional details to the FCC at least 45 days before a planned launch for the next three years.

While it was noted that the fine was relatively small, it had been increased from an initial amount agreed between the company and the FCC Enforcement Bureau. An FCC Commissioner observed that the negative publicity would probably prevent repetitions by Swarm or others.[26]

Satellite constellation

[edit]
  • SpaceBEE is a constellation of picosatellites, predominantly in the CubeSat 0.25U form factor, intended to reach a quantity of 150.[27] SpaceBEE test models 5 to 9 were larger to assuage concerns about radar tracking. Swarm's website lists the satellites' mass at 400 g and size at 110 × 110 × 28 mm.
  • SpaceBEE NZ is another constellation of satellites by Swarm Technologies. As of November 2024, 22 SpaceBEE NZ satellites have been launched, and all have decayed from orbit. The last SpaceBEE NZ (SpaceBEE NZ 22) decayed from orbit 23 January 2024.

Swarm Technologies, LLC was an American aerospace startup founded in 2017 that specialized in developing and operating a constellation of small satellites to provide low-cost, global two-way (IoT) connectivity. The company designed pico-satellites called SpaceBEEs, which were among the world's smallest operational two-way communications satellites, enabling remote and data transmission with 100% global coverage via low-power protocols like LoRaWAN adapted for . Swarm achieved notable technical milestones, including the deployment of over 120 SpaceBEE satellites by 2021 and integration of its network for end-to-end IoT solutions in industries such as and . However, the company faced significant regulatory controversy when it launched four prototype SpaceBEEs in January 2018 without U.S. (FCC) authorization, leading to unauthorized orbital operations and a $900,000 fine in December 2018 for violating licensing requirements and conducting unapproved tests. In July 2021, acquired Swarm to bolster its constellation's IoT capabilities, transitioning the service toward LTE-based satellite connectivity while maintaining support for existing Swarm users. This acquisition has since contributed technologies like thrusters to satellites, demonstrating ongoing value from Swarm's innovations despite its independent regulatory challenges.

Founding and Early History

Company Establishment

Swarm Technologies, Inc. was founded in 2016 by engineers Sara Spangelo and Benjamin Longmier in . The company was established to address limitations in global IoT connectivity by developing a satellite capable of providing two-way communications for remote devices, targeting applications in , , and where terrestrial networks are unavailable. Spangelo and Longmier, drawing on their technical expertise, positioned Swarm as a provider of cost-effective solutions using CubeSat-derived , with an initial focus on store-and-forward systems to enable messaging from battery-powered sensors worldwide. The firm's early operations emphasized prototyping small satellites under 1U in size to minimize launch costs and facilitate rapid deployment.

Initial Development and Funding

Swarm Technologies was founded in 2016 by aerospace engineers Sara Spangelo and Benjamin Longmier to develop a low-cost satellite constellation for global Internet of Things (IoT) connectivity using a store-and-forward communication architecture. Spangelo, who previously worked at NASA on small satellite projects and at Google on drone delivery systems and technology investments, served as CEO, while Longmier, formerly at Apple and co-founder of high-altitude platform company Aether Industries, became chief technology officer. The company operated in stealth mode initially, focusing on prototyping tiny CubeSat-based satellites known as SpaceBEEs, designed to enable affordable data transmission from remote IoT devices without relying on continuous real-time links. Early development emphasized minimizing size, cost, and power consumption to achieve broad orbital coverage for applications like and . The SpaceBEE prototypes, measuring approximately 10 cm per side and weighing under 1 kg, incorporated modulation for efficient, low-bandwidth messaging, allowing devices to send small data packets that satellites would to ground stations upon passing overhead. This approach contrasted with higher-power geostationary or low-Earth orbit systems, prioritizing scalability for a planned 150- network over high-speed connectivity. Funding began with a $740,000 grant from the on March 15, 2018, to support experimental validation of the technology, marking the company's first external capital infusion. This was followed by a $25 million Series A round closed on January 24, 2019, led by and including investments from , founder of , and David Sacks, co-founder of , to finance prototype testing, regulatory compliance, and initial constellation deployment. The round brought total funding to approximately $25 million at that point, enabling the company to scale beyond prototypes despite ongoing regulatory hurdles.

Technological Innovations

Satellite Design and SpaceBEE Prototypes

The SpaceBEE satellites developed by Swarm Technologies adhere to the 0.25U standard, with dimensions of approximately 110 mm × 110 mm × 28 mm and a of 0.25 kg, positioning them as among the smallest satellites capable of . This compact form factor incorporates a store-and-forward utilizing modulation for low-power, long-range data relay, operating on VHF frequencies including 137–138 MHz for downlink and 148–150 MHz for uplink, enabling intermittent IoT connectivity over global coverage. The design features deployed quarter-wavelength split-dipole antennas providing a donut-shaped gain pattern to optimize signal reception across a wide , with radar cross-section enhancements in early models to aid tracking despite their diminutive size. Prototyping efforts commenced following Swarm's founding in 2016, focusing on validating the viability of a low-cost IoT constellation through minimal viable satellites. The initial four prototypes, designated SpaceBEE 1 through 4, were 0.25U units with experimental signature improvements but proved too small for consistent ground-based tracking, prompting FCC scrutiny over orbital risks and interference potential. These were deployed without U.S. regulatory approval on January 12, 2018, via India's PSLV-C40 rocket, serving as proof-of-concept for the store-and-forward mechanism by relaying test data packets during orbital passes. Subsequent prototypes, including SpaceBEE 5 through 9, underwent refinements to address size and performance issues, with some iterations weighing 0.4–0.7 kg before operational models standardized back to the 0.25U baseline for scalability. These tests confirmed the satellites' ability to handle 15- to 87-byte packets for IoT applications, such as in remote areas, while iterating on power efficiency and antenna deployment reliability. The prototype phase informed the full constellation design, emphasizing through off-the-shelf components and simplified to achieve data rates sufficient for applications without real-time connectivity demands.

Store-and-Forward Communication System

Swarm Technologies implemented a store-and-forward architecture in its SpaceBEE to facilitate low-power, bidirectional communication with (IoT) devices across remote and global locations. In this system, IoT endpoints equipped with compatible modems transmit compact data packets—typically limited to 1-10 bytes per message—uplink to passing satellites via (VHF) bands around 137-150 MHz. The satellites, operating in at altitudes of approximately 550 km, receive these packets using onboard antennas and store them in solid-state memory until the spacecraft enters visibility of a ground gateway station, at which point the data is downlinked for routing to end users. This batched relay mechanism avoids the need for persistent satellite-to-ground links, minimizing onboard processing demands and enabling operation with picosatellite form factors as small as 0.25U CubeSats. The architecture incorporated and LoRa-based modulation for uplink resilience, allowing transmissions from battery-constrained devices over distances up to several kilometers with effective isotropic radiated power under 1 watt. Downlinks to gateways utilized higher-power bursts in the 400 MHz range, supporting aggregate throughputs sufficient for IoT-scale messaging volumes, such as sensor readings or location pings from assets like shipping containers or agricultural equipment. Swarm's design targeted applications requiring infrequent, non-real-time updates, with end-to-end latency varying from to several hours based on orbital geometry, constellation coverage, and gateway density—factors that improved as the network scaled to over 100 satellites by 2021. This approach prioritized cost-efficiency and simplicity over continuous connectivity, distinguishing it from bent-pipe or direct-to-cell systems by reducing spectrum usage and satellite complexity; each SpaceBEE featured minimal subsystems, including a single-string and no , to achieve per-unit costs below $100,000. Reliability was enhanced through redundant packet queuing and acknowledgments, with the system demonstrating over 99% message delivery rates in operational tests prior to commercial rollout. However, the store-and-forward model's inherent delays limited its suitability for time-sensitive applications, positioning it primarily for monitoring scenarios where data freshness tolerances exceeded orbital revisit intervals of 1-2 hours in mid-latitudes.

IoT Applications and Target Markets

Swarm Technologies' SpaceBEE primarily supports (IoT) applications requiring low-bandwidth, store-and-forward communication for remote sensors and devices lacking terrestrial cellular coverage. This architecture enables global connectivity at reduced costs compared to traditional satellite providers, targeting data transmission rates suitable for periodic updates rather than real-time streaming. Key use cases involve deploying compact modems integrated with technology for energy-efficient messaging from isolated locations, such as deserts, oceans, or polar regions. Target markets encompass sectors where asset visibility and environmental data are critical but infrastructure is sparse. In , Swarm's network facilitates soil sensors, livestock trackers, and irrigation monitors, enabling farmers to optimize resources across vast, rural expanses without relying on ground-based networks. The maritime industry utilizes the service for vessel position reporting and cargo monitoring, addressing coverage gaps in open seas. In energy and utilities, applications include pipeline integrity checks and remote meter readings, supporting in oil fields or power grids. Additional markets include transportation and for tracking vehicles, containers, and equipment in transit across unconnected terrains, as well as via buoys or fixed sensors for ocean data, wildlife tracking, or . Specialized cases extend to for distribution and remote worker safety in or exploration. These applications leverage Swarm's cost advantage—often cited as one-tenth that of legacy providers—for scalable deployment of thousands of endpoints. Following the 2021 acquisition by , Swarm's IoT focus has integrated with broader satellite ecosystems, though core low-data-rate markets persist.

Launches and Regulatory Challenges

2018 Unauthorized Launch via PSLV

In January 2018, Swarm Technologies arranged for the deployment of four prototype SpaceBEE satellites as secondary payloads on an Indian Space Research Organisation (ISRO) Polar Satellite Launch Vehicle (PSLV) rocket, without obtaining required authorization from the U.S. Federal Communications Commission (FCC). The launch, designated PSLV-C40, lifted off on January 12, 2018, from the on India's eastern coast, primarily carrying the Cartosat-2 series satellite as the main payload. The deployment opportunity was brokered by , which facilitated rideshare access for small satellites on the Indian vehicle. Swarm had submitted an application for an experimental license to test the satellites' store-and-forward communication systems in November 2017, but the FCC dismissed it on December 14, 2017, due to unresolved concerns about orbital tracking accuracy. The prototypes, each measuring roughly 10 cm × 10 cm × 2.5 cm (about the size of a sandwich) and weighing under 1 kg, were deemed too small for reliable conjunction assessments, potentially endangering other by complicating collision avoidance calculations under international norms. Swarm proceeded despite the denial, maintaining that the satellites would adhere to (ITU) filing procedures for frequency coordination rather than seeking full FCC orbital slot approval, though this bypassed U.S. regulatory oversight for domestic entities operating radio frequencies. The SpaceBEE units were inserted into a , enabling periodic data relay for IoT applications via VHF/UHF bands. This marked the first instance of a U.S. company launching operational satellites without government permission, highlighting tensions between rapid commercialization of smallsats and established regulatory frameworks for spectrum use and orbital safety. The action drew immediate industry concern over precedents for regulatory evasion, as the satellites' untrackable nature could contribute to orbital debris risks without verifiable deorbiting plans. Public disclosure of the launch in early March 2018 prompted the FCC to launch an enforcement inquiry, revoking Swarm's separate authorization for a planned April 2018 rocket deployment and scrutinizing unauthorized operations in Georgia. Swarm defended the move as necessary to validate technology amid bureaucratic delays, but regulators emphasized that such unilateral actions undermined safeguards against interference in shared orbital domains.

FCC Investigation and $900,000 Fine

In December 2017, the (FCC) denied Swarm Technologies' application for an experimental license to operate four prototype satellites, citing concerns that the small 1.5U CubeSats—measuring approximately 10 cm x 10 cm x 15 cm—lacked sufficient tracking capabilities compatible with the U.S. Space Surveillance Network, potentially increasing collision risks in . Despite this denial, Swarm proceeded to deploy the satellites, named SpaceBEE prototypes, as secondary payloads on an Indian Space Research Organisation PSLV launch from on January 12, 2018, without obtaining FCC authorization for their operation, including associated earth stations and radio frequency equipment. The FCC initiated an investigation into Swarm's actions shortly after the launch became public knowledge in March 2018, focusing on violations of Section 301 of the Communications Act, which prohibits unauthorized operation of communications devices. Swarm admitted to the unauthorized deployment and operations but argued that the satellites' store-and-forward architecture minimized interference risks; however, the FCC emphasized the broader regulatory imperative for pre-launch approval to ensure orbital safety and , rejecting such justifications as insufficient to override statutory requirements. On December 20, 2018, the FCC resolved the investigation through a with Swarm, imposing a $900,000 —the first such fine for an unauthorized U.S. launch—along with a five-year compliance plan that included enhanced reporting obligations, pre-launch coordination requirements for future operations, and ongoing FCC oversight to prevent recurrence. The settlement underscored the FCC's authority over commercial space communications amid growing deployments, while Swarm ceased operations of the unauthorized prototypes pending further approvals, which were later granted experimentally in October 2018 for testing. Following the December 20, 2018, with the (FCC), Swarm Technologies implemented a five-year compliance plan that mandated enhanced internal procedures for regulatory adherence, including pre-launch notifications to the FCC at least 30 days prior to any satellite deployment, detailed reporting on operational status, and routine audits to ensure adherence to Sections 301 and 302 of the Communications Act regarding unauthorized radio transmissions and equipment use. The decree also required Swarm to pay a $900,000 in installments over five years, with the funds directed to the U.S. Treasury, and subjected the company to ongoing FCC oversight to prevent recurrence of unapproved launches or operations. Under this framework, Swarm secured FCC authorization for experimental operations of three additional SpaceBEE satellites in September 2018, prior to the decree's finalization but aligned with emerging compliance efforts, enabling their integration into planned missions while addressing prior tracking deficiencies. In October 2019, the FCC granted Swarm a full license for a non-voice, non-geostationary mobile satellite service (NVNG MSS) system, permitting the deployment and operation of up to 150 SpaceBEE satellites in low Earth orbit at altitudes between 540 and 580 kilometers, with specific frequency allocations in the 137-138 MHz and 148-149.9 MHz bands for store-and-forward IoT communications. This approval incorporated orbital debris mitigation measures, such as a commitment to deorbit satellites within five years of mission end and compliance with international coordination via the International Telecommunication Union (ITU). Swarm's post-decree launches, including those aboard missions in 2019 and 2020, proceeded under these authorizations, with the company demonstrating improved telemetry reporting to mitigate interference risks with other satellite systems. No further FCC enforcement actions were reported against Swarm prior to its 2021 acquisition by , indicating successful adherence to the compliance regime.

Expansion and Constellation Buildout

Licensed Launches and Orbital Deployments

Following the $900,000 settlement with the FCC in December 2018, Swarm Technologies executed its initial licensed orbital deployment on December 3, 2018, launching SpaceBEE satellites 5, 6, and 7 aboard a rocket during the SSO-A rideshare mission from Vandenberg Air Force Base into a at approximately 500 km altitude. These satellites, authorized by the FCC in September 2018, marked the company's compliance with pre-launch notification requirements and operational tracking protocols. In mid-2019, Swarm deployed SpaceBEE 8 and 9 via a rocket into a 45-degree inclined , expanding testing of the store-and-forward communication system under experimental authority. The FCC subsequently granted Swarm a full on October 17, 2019, to construct, deploy, and operate up to 150 technically identical non-voice, non-geostationary satellites in , operating in the 137-138 MHz and 148-149.9 MHz bands for space-to-Earth and Earth-to-space communications, respectively, with a planned orbital regime between 525 and 575 km altitude. This approval enabled systematic constellation buildout, requiring Swarm to implement collision avoidance maneuvers and deorbit capabilities within five years of deployment. The company's licensed deployments accelerated in 2020 with the launch of 12 third-generation SpaceBEE satellites on September 3, 2020, aboard an Vega rocket via the SSMS (Small Spacecraft Mission Service) rideshare from into a . Subsequent batches followed, including additional satellites integrated into multi-payload missions on , , and other vehicles, achieving orbital insertions primarily in sun-synchronous and mid-inclination paths to support global IoT coverage. By mid-2021, prior to SpaceX's acquisition, Swarm had deployed over two dozen licensed SpaceBEEs, with ongoing launches post-acquisition continuing under the FCC license until the constellation's operational phaseshift. Key licensed launches are summarized below:
DateLaunch VehicleOperatorSatellites DeployedOrbit Details

June 12, 202312Sun-synchronous, ~500 km
These deployments prioritized rapid iteration on design while adhering to international tracking standards via the 18th Space Control Squadron and compliance with space debris mitigation guidelines.

Growth of the SpaceBEE Constellation

Following regulatory approvals from the (FCC) in late 2018, Swarm Technologies accelerated the deployment of its SpaceBEE satellites via rideshare opportunities on commercial launch vehicles, primarily SpaceX missions. Initial operational satellites joined prototypes in , with the constellation expanding from seven SpaceBEE units by December 2018—after a batch of three launched on the SpaceX SSO-A mission on December 3—to nine by October 2019. This buildup supported Swarm's target of a 150-satellite network for global IoT coverage, funded in part by a $25 million announced in 2019 dedicated to full constellation deployment. Launches in 2020 added dozens more, leveraging cost-effective secondary payloads to achieve redundancy and diversity for improved store-and-forward messaging reliability. By December 2020, operational satellites numbered in the high dozens, with further batches—including 48 additional units by late 2021—pushing the total to 81, the threshold for initiating beta commercial services. The constellation's expansion emphasized picosatellite scalability, with each 0.25U SpaceBEE (11 cm × 11 cm × 3 cm, approximately 400 grams) designed for rapid production and minimal launch costs, enabling Swarm to outpace initial projections despite early regulatory hurdles. This growth phase culminated in over 120 satellites in orbit by mid-2021, providing near-continuous coverage for low-data-rate IoT applications in remote areas.

Commercial Service Rollout

Swarm Technologies commenced commercial operations for its SpaceBEE satellite constellation in early 2021, following FCC authorization for experimental operations in late 2020 and the deployment of initial operational satellites. By December 2020, the company had launched 36 operational SpaceBEE satellites, enabling the transition from testing to revenue-generating services by the end of January 2021. On February 9, 2021, Swarm announced the full commercial availability of its global IoT data service, leveraging a constellation of 72 satellites to deliver store-and-forward VHF communications for low-bandwidth applications such as and remote monitoring. The service offered tiered pricing starting at $5 per device per month for up to 750 messages, positioning it as a cost-competitive alternative to traditional IoT providers for intermittent data needs in underserved regions. Early adopters included sectors like maritime, , and , where the system's ability to handle delayed non-real-time messaging supported applications such as container tracking and environmental sensors without requiring continuous connectivity. Swarm emphasized the service's reliability through partnerships, including deployments in remote locations to ensure global coverage, though initial capacity was limited by the partial constellation buildout. This rollout marked Swarm's shift from demonstrations to scalable customer deployments, with the company reporting rapid hardware and to meet demand prior to its acquisition later that year.

Acquisition by SpaceX

2021 Deal Details and Valuation

SpaceX and Swarm Technologies reached a merger agreement on July 16, 2021, under which Swarm would operate as a wholly owned subsidiary of SpaceX. The deal's existence came to public attention through U.S. Federal Communications Commission (FCC) filings submitted on August 6, 2021, requesting approval for the transfer of Swarm's satellite and ground station licenses to SpaceX control. These filings detailed the operational continuity of Swarm's approximately 120 SpaceBEE satellites in orbit but omitted any financial terms or valuation specifics. The acquisition's financial details, including the purchase price and final valuation of Swarm, were not publicly disclosed in the FCC documentation or subsequent announcements. Prior to the deal, Swarm had raised nearly $28 million in funding and completed its last known round in January 2019 at an $85 million post-money valuation, per PitchBook data.

Strategic Rationale and Integration Benefits

SpaceX's acquisition of Swarm Technologies in 2021 was driven by the opportunity to integrate Swarm's specialized low-Earth orbit (LEO) satellite technology for Internet of Things (IoT) connectivity into its broader satellite ecosystem, diversifying beyond high-bandwidth consumer internet services like Starlink. Swarm's SpaceBEE satellites, which enable low-data-rate communications for applications such as asset tracking and remote sensing, complemented SpaceX's launch capabilities and manufacturing scale, allowing for more efficient deployment of small satellites without relying on third-party rideshares. This move aligned with SpaceX's aim to capture niche markets in global connectivity where traditional infrastructure falls short, particularly in underserved regions requiring intermittent, cost-effective data transmission. Integration benefits included enhanced access to Swarm's intellectual property and engineering expertise in miniaturized satellite design and packet-based IoT protocols, which SpaceX could apply to optimize its own constellation operations and reduce per-satellite costs. By absorbing Swarm, SpaceX gained synergies in orbital slots, , and ground infrastructure, enabling faster scaling of the SpaceBEE constellation—projected to grow beyond its initial 150 satellites—through dedicated launches that lowered deployment expenses compared to Swarm's prior arrangements. The combined entity improved service reliability for IoT customers by leveraging SpaceX's financial resources for constellation maintenance and expansion, while overlapping customer bases in maritime, , and sectors facilitated cross-selling opportunities between Swarm's low-cost IoT and Starlink's offerings. Furthermore, the acquisition strengthened regulatory positioning, as the FCC filing emphasized how the merger would bolster compliance and innovation in serving unserved areas, mitigating past scrutiny over Swarm's unauthorized 2018 launch. Post-integration, Swarm's technology contributed to SpaceX's strategy, potentially informing advancements in and swarm coordination for resilient networks, though primary focus remained on commercial IoT expansion rather than direct enhancements. Overall, these benefits positioned SpaceX to monetize IoT services more effectively, with Swarm's $5-per-month connectivity model gaining scalability under SpaceX's operational umbrella.

Post-Acquisition Developments

Following the July 2021 acquisition of Swarm Technologies by , key personnel from Swarm contributed expertise in electric systems to the development of advanced thrusters for Starlink satellites. Swarm co-founder Benjamin Longmier, who specialized in plasma during his prior roles at the and , assumed leadership of Starlink's electric group, enabling rapid iteration on new designs. Similarly, co-founder Sara Spangelo joined as senior director of satellite engineering, supporting broader integration of advancements into satellite operations. A primary outcome was the deployment of argon-based Hall-effect thrusters on V2 Mini satellites, with development commencing around August 2021 and achieving orbital flight in approximately 556 days by early 2023. These thrusters utilize as the , which is more abundant and cost-effective than alternatives like or previously employed in systems, reducing operational expenses while maintaining high performance. Compared to prior iterations, the argon thrusters deliver 2.4 times greater and 1.5 times higher , enhancing capabilities for orbit raising, attitude control, collision avoidance, and end-of-life deorbiting. This improvement supports the constellation's requirements for precise maneuvering in amid increasing satellite density. Swarm's prior work on compact for its SpaceBEE picosatellites, which necessitated efficient, low-mass systems for small-form-factor , informed these advancements, bridging IoT-scale engineering to needs. The integration has enabled to scale its constellation more reliably, with thrusters now standard on newer generations for sustained orbital maintenance without frequent ground interventions. While Swarm's core IoT communication protocols have primarily extended to 's service offerings rather than core hardware, the innovations represent a direct technological transfer that bolsters 's efficiency and longevity.

Service Expansion and Global Reach

Following its acquisition by in August 2021, Swarm Technologies expanded its IoT satellite service by leveraging 's frequent rideshare launch opportunities to deploy additional SpaceBEE satellites, thereby enhancing constellation density and orbital distribution for improved global coverage. By mid-2022, the network had grown to approximately 175 operational satellites, enabling more consistent store-and-forward communications for low-power, low-data-rate IoT devices across remote and underserved regions. This buildout supported bidirectional messaging with reduced latency, guaranteeing delivery times under one hour for most transmissions by July 2022, a marked improvement over initial experimental phases. The service's global reach manifested in its ability to provide near-continuous coverage over populated landmasses and maritime areas, targeting applications such as , , and in areas lacking terrestrial . Swarm's , utilizing UHF and VHF bands for compact 0.25U CubeSats, allowed for cost-effective , with the expanded constellation achieving effective visibility passes multiple times daily for devices worldwide. Post-acquisition deployments continued through June 2023, culminating in over 180 before production halted, solidifying Swarm's position as a provider of affordable IoT prior to its planned decommissioning. Commercially, Swarm pursued geographic expansion by entering new regulatory markets, operating in 17 countries as of September 2022 with ambitions to serve 40 by 2024, focusing on regions with high demand for disconnected IoT solutions like and shipping. This growth emphasized low-cost pricing—often one-tenth that of competitors like —while maintaining compliance with international spectrum allocations, though service was eventually constrained by the 2025 constellation sunset.

2025 Constellation Sunset and Transition

In September 2024, announced the discontinuation of Swarm Technologies' commercial satellite IoT service, with operations ceasing in March 2025 due to the natural degradation of the existing 150-satellite SpaceBEE constellation and the absence of planned replenishment launches. The store-and-forward VHF system, designed for low-bandwidth messaging via Swarm Tile modems, had already seen increasing latencies beginning in November 2024, doubling in some cases as satellite coverage diminished. This followed the halt of new device sales and customer onboarding in 2023, after the constellation reached its licensed full deployment of 150 spacecraft. The decision reflected a strategic pivot away from maintaining the aging, low-data-rate toward SpaceX's direct-to-cell (D2D) capabilities, which integrate IoT connectivity with higher-capacity LTE-compatible services using modified satellites. Existing Swarm subscribers were not charged for data plan renewals post-announcement and retained access until the March 2025 cutoff, after which all SpaceBEE-linked devices, including modules with prepaid credits, permanently ceased transmission. No automated migration path was provided, requiring users to deployments, back up historical , and transition to alternatives, potentially incurring service interruptions of at least 24 hours. Post-sunset, the Swarm website (swarm.space) redirected to SpaceX's D2D informational page, signaling the integration of Swarm's acquired IoT expertise into broader ecosystem expansions. SpaceX's D2D rollout, targeting IoT applications by 2025, leverages over 180 dedicated satellites (as of early 2025 launches) for global, unmodified LTE device connectivity, offering improved latency and bandwidth over Swarm's VHF approach without requiring proprietary hardware. The constellation's deorbiting aligned with end-of-life protocols to mitigate orbital , though specific timelines for individual satellite passivation were not publicly detailed beyond the service termination. This transition underscored the obsolescence of early nanosatellite IoT designs in favor of scalable, multi-use LEO networks.

Impact and Criticisms

Achievements in Low-Cost Satellite IoT

Swarm Technologies achieved breakthroughs in IoT by deploying the SpaceBEE constellation, consisting of compact nanosatellites weighing approximately 1.5 kilograms each, which provided low-power, two-way communications for remote devices using VHF spectrum. This design enabled global coverage for IoT applications like , maritime monitoring, and agricultural sensing, where terrestrial networks were unavailable, at costs far below those of established geostationary or legacy LEO providers. By leveraging rideshare launches on rockets, Swarm minimized deployment expenses, launching initial test satellites in 2018 and scaling to over 36 production units by late 2020 as part of a planned 150-satellite network. A key milestone was the commercialization of services in February 2021, with data plans starting at $5 per month for up to 750 packets of 192 bytes each, paired with the $119 Swarm Tile modem that integrated easily into existing IoT hardware. This pricing undercut competitors by an , as traditional satellite IoT solutions often exceeded $50 per month for similar low-data volumes; for instance, one in reduced costs from NZ$450 to under NZ$15 monthly. The system's low latency for store-and-forward messaging—typically minutes to hours—suited non-real-time use cases, broadening adoption in industries requiring intermittent, reliable data relay without high-bandwidth demands. Swarm's innovations demonstrated the feasibility of mass-producing and operating picosatellites for IoT, using simplified antennas and protocols to achieve detection rates over 95% for asset location, even in challenging environments like oceans or polar regions. By securing FCC authorization in for its full constellation despite initial regulatory hurdles over tracking, the company validated a model that prioritized affordability and , paving the way for subsequent entrants in low-cost satellite IoT while serving thousands of devices pre-acquisition.

Criticisms of Regulatory Evasion and Risks

Swarm Technologies faced significant regulatory scrutiny in 2018 for launching four prototype SpaceBEE satellites (each approximately 10 cm × 10 cm × 15 cm) aboard a rocket on January 12 without prior authorization from the U.S. (FCC). The FCC had denied Swarm's application for an experimental license in December 2017, citing concerns that the satellites' small size and low radar cross-section would render them untrackable by the U.S. Space Surveillance Network, thereby increasing collision risks with other orbital assets and complicating space traffic management. Additionally, the agency highlighted inadequate mitigation plans for orbital debris, as the satellites lacked guaranteed deorbiting mechanisms within regulatory timelines, potentially exacerbating the growing problem of in . Critics, including FCC officials and industry analysts, accused Swarm of deliberate regulatory evasion by proceeding with the launch despite the denial, arguing that such actions undermined established international norms for spectrum allocation and orbital safety under the and FCC rules. The unauthorized operation also involved unapproved ground stations in Georgia for communicating with the satellites, raising risks of radio frequency interference with licensed users, which could disrupt critical commercial and government satellite services. In response to an FCC investigation launched in March 2018, Swarm settled the matter on December 20, 2018, agreeing to a $900,000 —the first such fine for an unauthorized satellite deployment—along with a five-year compliance plan requiring pre-launch notifications and enhanced oversight. The incident drew broader industry criticism for potentially inviting stricter regulations on deployments, as unauthorized launches could erode trust in self-certification processes and heighten demands for verifiable tracking technologies amid the proliferation of mega-constellations. While Swarm contended that the launch demonstrated the satellites' trackability—claiming all four were located post-deployment—regulators and experts maintained that proactive compliance is essential to prevent cascading events, noting that even small objects traveling at orbital velocities (around 7.8 km/s) pose lethal threats to manned and unmanned missions. This event underscored risks associated with "move fast and break things" approaches in space, where evasion of licensing could prioritize commercial haste over public safety and long-term sustainability of the orbital environment.

Broader Industry Influence

Swarm Technologies advanced the IoT industry by pioneering affordable, nanosatellite-based connectivity for low-bandwidth applications, enabling global coverage for remote sensors and devices at costs far below traditional geostationary systems. Launched in 2018, its SpaceBEE CubeSats—measuring just 11 cm cubed—demonstrated reliable two-way data transmission using modulation, achieving data rates of up to 300 bits per minute while consuming minimal power. This innovation lowered entry barriers for IoT deployments in sectors like , , and , where terrestrial networks fail, and influenced competitors to pursue similar direct-to-orbit architectures. By 2021, Swarm's model had validated the economic feasibility of proliferated low-Earth orbit (LEO) constellations for non-broadband uses, contributing to the market's projected growth from $6.50 billion in 2025 to $11.28 billion by 2029. The company's 2021 acquisition by amplified its influence through technology transfer and market consolidation trends. Swarm's propulsion expertise, including compact thrusters, directly enhanced satellite maneuvers, improving constellation efficiency and deorbiting reliability. Post-acquisition, Swarm expanded into new verticals, scaling sales and production tenfold by mid-2022 while leveraging 's launch cadence, which underscored synergies between niche IoT providers and mega-constellations. This deal exemplified the satellite sector's shift toward , where incumbents acquire startups to preempt competition and accelerate direct-to-device capabilities, amid rising demand for hybrid terrestrial-satellite IoT networks. Swarm's regulatory precedents also shaped industry practices, particularly around smallsat tracking and licensing. In 2018, the FCC denied initial authorization due to unproven ground-based localization, yet Swarm proceeded with launches, prompting fines and heightened scrutiny of orbital debris risks from hard-to-detect picosats. These events catalyzed discussions on adaptive regulations for swarm architectures, influencing frameworks like the FCC's 2020 rule updates for commercial and emphasizing causal factors such as limitations in causal risk assessments for LEO congestion. The 2025 sunsetting of Swarm's original constellation further highlighted transition challenges, paving the way for evolved standards in sustainable, low-cost IoT orbits.
