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.

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

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

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.

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

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.

In July 2023, the company stopped new device sales.

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