Perlego is a digital library that offers readers unlimited access to over 1.3 million academic, professional and non-fiction ebooks. Billed as the "Spotify for textbooks" by the Evening Standard,[1] it is a membership-based service that allows users to read any book available in the library for the duration of their membership.[2]

Key Information

Perlego offers ebooks in 8 languages: English, Spanish, Italian, German, French, Portuguese, Swedish and Dutch, from local and international publishers. The service is available worldwide and allows users to read both online and offline on most smartphones, tablets or laptop devices.

History

[edit]

Perlego was founded in 2017 in London, United Kingdom, by Gauthier Van Malderen and Matthew Davis, both Belgian natives and recent university graduates.[3] Drawing from their personal experiences with the high and rising cost of university textbooks, and noting the convenience of accessing music and films via subscription models like Netflix and Spotify, the founders aimed to increase global access to academic resources.[4] They did this by offering students an "all-you-can-read" subscription model, providing a more affordable and convenient alternative to purchasing new textbooks while aiding publishers in reclaiming market share lost to online piracy.[4]

In January 2025, Perlego was listed in the Sunday Times ranking of the 100 fastest-growing technology firms in the UK.[5]

Funding

[edit]

Perlego was initially self-funded. Its pre-seed funding was derived from the profit made from Gauthier's previous business venture – Iconic Matter.[6] In January 2017, Perlego raised £850,000 in a round of seed funding. This was led by angel investors from the UK, Belgium and France, with Zoopla founder Alex Chesterman and LoveFilm founder Simon Franks being notable participants.[7][8] In September 2018, Perlego raised a further £3,500,000 in a venture round led by Accelerated Digital Ventures, with further participation from its existing angel investors.[6] In November 2019, Perlego closed its Series A fundraising round, having raised a total of £7,000,000. The fundraising was led by Charlie Songhurst, Dedicated VC, and Thomas Leysen (Chairman of Mediahuis and Umicore), with Perlego's existing investors all reinvesting on a pro-rata basis.[9] In March 2022, Perlego closed its Series B fundraising round, raising $50,000,000. The round was led by Mediahuis Ventures.[4] In October 2024, Perlego announced a $20,000,000 fundraising led by Sir Terry Leahy, the former Tesco CEO.[10]

[edit]

In 2023, Perlego's digital library contained over one million academic e-textbooks in eight languages,[11][12] covering more than 900 disciplines from aeronautics to zoology. At the moment Perlego works with over 9,000 publishers who provide content for the service, including major academic publishers such as Wiley and Bloomsbury.[13][14]

Users can access titles via their browser on desktop computers or download an application on mobile devices where it is also possible to download books for offline reading. Study tools include highlights, making notes and the text-to-speech feature Read Aloud.[15][16] In 2024, Perlego launched two artificial intelligence tools, Smart Search and AI Researcher.[17]

Perlego partnered with the University of West London in 2022 to provide its full catalogue to its students.[18] September 2024 saw Perlego launch a partnership with the University of Leeds, a Russell Group member that serves nearly 40,000 students, to offer unlimited access to its digital library.[19] In 2025, Perlego launched a partnership with Westcliff University in the US.[12]

History

Founding

Perlego was founded by Gauthier van Malderen and Matthew Davis, two Belgian entrepreneurs who met as friends at the European School during their studies. Van Malderen, who serves as CEO, had previously established and exited Iconic Matter, a youth-oriented marketing company that partnered with universities across Belgium, Switzerland, and Morocco for online and on-campus advertising, while Davis, the CTO, shared a background in addressing educational access challenges. Their collaboration stemmed from personal experiences as university students, where they identified the prohibitive expenses associated with academic materials as a major barrier to learning.[8][10][3][11][12] The core motivation for Perlego arose from the escalating costs of academic textbooks, which have increased by over 1,000% since the late 1970s—far outpacing general inflation—and often reached £200 or more per book in the UK market around 2017.[13] This financial burden limited access for students and professionals alike, prompting van Malderen and Davis to envision a subscription-based digital library that would democratize educational resources, much like Netflix and Spotify had done for entertainment and music. By providing unlimited access to textbooks for a flat monthly fee, they aimed to eliminate the need for expensive one-time purchases and outdated physical copies.[11][14] Officially founded in 2016 and launched in January 2017 in London, UK, Perlego began operations without external investment, relying instead on self-funding from the profits of van Malderen's Iconic Matter exit. This bootstrapped approach allowed the duo to develop the platform's initial infrastructure, focusing on a user-friendly online service for e-books tailored to higher education needs. Early development emphasized solving accessibility issues, setting the stage for Perlego's role as an edtech innovator in textbook affordability.[11][15]

Funding

Perlego was initially bootstrapped using profits from founder Gauthier van Malderen's previous venture, Iconic Matter, a youth-oriented marketing company that partnered with universities across Belgium, Switzerland, and Morocco for online and on-campus advertising.[11][12] The company's first external funding came in the form of a seed round in January 2017, raising £500,000 from private angel investors based in the United Kingdom, Belgium, and France. This capital supported the platform's early development and beta launch later that year, addressing the high costs of academic textbooks through a subscription-based e-book model.[16] In September 2018, Perlego secured a $4.8 million venture funding round led by Accelerated Digital Ventures (ADV), with participation from existing angels including Simon Franks (co-founder of Lovefilm) and Alex Chesterman (founder of Zoopla). The funds were allocated to expanding the team, scaling operations across the UK and Europe, and enhancing product features for students and professionals.[17] Perlego's Series A round in November 2019 raised $9 million (approximately £7 million), led by Charlie Songhurst, a former Google board member and corporate officer, alongside Dedicated VC and Thomas Leysen (Chairman of Mediahuis and Umicore). Existing investors such as ADV, Franks, and Chesterman also participated pro-rata. This investment focused on growing the e-book library and broadening access to educational content in 28 European countries.[18] The Series B round, closed in March 2022, brought in $50 million led by Mediahuis Ventures, with contributions from Raine Ventures, Evli Growth Partners, and angels including the co-founders of Kahoot via their We Are Human fund. The proceeds enabled accelerated international expansion, particularly into the US market, and platform enhancements to support over 850,000 titles and 400,000 subscribers amid post-pandemic demand.[19] In October 2024, Perlego raised an additional $20 million in a funding extension led by Sir Terry Leahy, former CEO of Tesco, with participation from ITHAKA, KPN Ventures, Mediahuis, Raine, and Kahoot founders. This round aimed at global scaling, making over one million academic titles available worldwide, and advancing AI integrations like the Dialogo research assistant to improve learning tools. As of October 2024, Perlego's total funding reached $75 million across multiple rounds.[6]

Growth and milestones

Following its founding, Perlego experienced rapid early growth in the UK higher education sector. By 2018, the company joined the Founders Factory Accelerator program, which supported its expansion and team development, leading to a £3.5 million venture funding round. In 2019, Perlego reported a 116% month-on-month increase in new subscribers, driven by its subscription model appealing to cost-conscious students amid rising textbook prices. This period marked initial profitability thresholds through efficient scaling of its user base in UK universities.[20][21] Perlego began international expansion in 2021, entering European markets including Germany, Switzerland, Austria, and France to broaden its reach beyond the UK. This was followed by entry into the US market in 2022, supported by a $50 million Series B funding round aimed at global scaling. To facilitate this growth, Perlego added multilingual support for books in English, Spanish, Italian, Portuguese, French, and German, enabling access for diverse non-English speaking users. By 2024, the platform served learners worldwide, with revenue reaching $41.3 million in 2023, reflecting sustained international adoption.[22][19][23][24] Key milestones include Perlego's ranking at 33rd on the Sunday Times 100 Tech list in January 2025, recognizing it as one of Britain's fastest-growing private tech firms based on three-year sales growth. The company has also appeared in prior high-growth rankings, underscoring its trajectory as an edtech leader. User base expansion shifted from a primary student focus to include professionals, growing to over 400,000 users by 2022 and continuing to scale with global partnerships.[25][26][27] Product evolution drove further growth, with the launch of institutional subscriptions in 2022, now adopted by over 250 universities and colleges worldwide for unlimited access to its library. In 2024, Perlego introduced AI tools such as AI Researcher and Dialogo, enhancing research capabilities and contributing to a 2024 revenue of £13.1 million, positioning the platform as a key driver in edtech innovation. In 2025, Perlego launched a partnership with Westcliff University in the US, expanding institutional access. By November 2025, titles from Life Sized Publishing were added to the platform, enhancing content for learners.[28][29][30]

Services and features

Subscription model

Perlego operates a subscription-based business model that grants users unlimited access to its digital library of academic, professional, and non-fiction ebooks, functioning as a streaming service for educational content similar to Netflix for textbooks. This approach emphasizes affordability and convenience, allowing subscribers to read as many titles as needed without purchasing individual books. The model supports flexible billing cycles, including monthly, termly (every four months), and annual options, with longer commitments often providing cost savings. As of 2025, individual plans start at $15 per month for the Essential tier.[31][28] The service features two primary tiers for individual users: Essential, priced at $15 monthly and providing access to over 800,000 titles across 900+ topics, and Complete, at $27 monthly, which expands to 1.4 million titles with additional premium tools like advanced AI research assistance and enhanced audio features. Institutional subscriptions, targeted at universities and organizations, operate on a per-user basis with unlimited access to the full collection, offering volume discounts for purchases of 50 or more subscriptions and customized pricing for larger orders exceeding 150 users. These institutional plans include administrative tools for user management and integrations with learning management systems, often negotiated to fit bulk needs. Discounts for students are available through university partnerships, embedding costs into tuition or providing subsidized access.[31][32] Access to content is delivered via Perlego's web platform and mobile app for iOS and Android, enabling reading on multiple devices with offline download capabilities for synced books. The model employs digital rights management (DRM) to protect content, restricting viewing to the Perlego eReader or app and limiting copying to 10% of a book, ensuring a rental-style experience without permanent ownership or transferability. This framework supports seamless searching, highlighting, and note-taking across devices.[33][31] Perlego primarily targets university students, who form the core of its user base through partnerships with over 250 institutions, alongside lifelong learners and professionals seeking ongoing education. The service reaches users in more than 175 countries worldwide, promoting global accessibility to academic resources.[34][5][35] The company's revenue streams are dominated by subscription fees, which constitute the main income source, supplemented by tiered premium features within plans. Publishers receive a significant revenue share, typically 65% of subscription earnings, to incentivize content provision.[36][19]

Content library

Perlego's content library comprises over 1 million ebooks, encompassing a vast array of academic and professional titles designed to support learners across diverse fields.[31] This collection spans more than 900 topics and subtopics, ranging from aeronautics to zoology, with particularly robust coverage in STEM disciplines such as engineering, computer science, and natural sciences; business and economics; and humanities including history, philosophy, and literature.[31] The library primarily features textbooks and non-fiction works, prioritizing specialized academic resources that are often difficult to access through traditional channels, while deliberately excluding mainstream fiction to maintain a focus on educational content.[1] All titles are available in digital formats, specifically EPUB for reflowable reading on various devices and PDF for fixed-layout preservation of original print structures, enabling seamless viewing on desktops, mobiles, and tablets.[37] The collection supports multiple languages, with English as the primary language and additional offerings in Spanish, Italian, Portuguese, French, and German, broadening accessibility for non-English-speaking users.[23] Content is sourced through licensing agreements with thousands of publishers, granting Perlego perpetual rights to distribute these titles within its subscription framework, ensuring a stable and expansive catalog without individual purchase requirements.[38] The library operates on a dynamic model, with thousands of new titles integrated monthly to reflect emerging research and curricular needs, allowing users to discover updated resources continuously.[39] This approach not only enhances the diversity of subjects but also supports interdisciplinary exploration, as users can access the full collection via subscription for unlimited reading and annotation.[33]

Technological tools

Perlego's core platform operates across web, iOS, and Android applications, enabling seamless access to its digital library on multiple devices. Users can download up to 30 ebooks at a time via the mobile app for offline reading, which is particularly useful for commuting or travel without internet connectivity. The platform supports interactive features such as searchable highlights, note-taking, and bookmarks, all organized in a centralized Notebook that syncs annotations across devices once reconnected to the internet. These tools allow users to add colored highlights, attach notes to specific text, and revisit them efficiently, enhancing retention and organization during study sessions.[40][41][42][43] For accessibility, Perlego incorporates a built-in text-to-speech (TTS) feature called Read Aloud, available for the majority of its ebooks on both web and mobile platforms. In 2025, the Read Aloud feature was expanded to include PDFs and additional titles, improving audio access for more content. This tool converts text to audio, supporting users with visual impairments or those preferring auditory learning, and is compatible with various browsers and devices. Customization options in the reader settings allow adjustments to font size, background color, and zoom up to 100%, further promoting inclusive reading experiences. While specific details on voice options and speed controls are integrated into the app's audio functionality, the feature emphasizes natural-sounding narration to maintain engagement.[44][45][41][46] In 2024, Perlego launched several AI-driven features to improve content interaction and research efficiency. The AI Researcher tool, introduced in April, enables semantic querying across the library by processing user inputs to suggest relevant books, excerpts, and targeted information from diverse sources, reducing the time needed for literature reviews. Complementing this, Smart Search uses AI to understand query context and meaning, delivering precise results beyond keyword matching. Personalized recommendations are generated based on user reading history and preferences, tailoring suggestions to individual academic needs. Additionally, the October 2024 release of Dialogo, an AI-powered research assistant, further streamlines topic exploration by aiding in source discovery and organization within the platform's vast catalog. These innovations stem from investments following the company's $50 million Series B funding in 2022 and a subsequent $20 million round in 2024, focused on advancing AI to support global education scalability.[29][47][48][6][49][19][6] Beyond core and AI functionalities, Perlego offers progress tracking tools to monitor reading habits and encourage consistency, including stats on active reading days, streaks, and overall completion rates to motivate users. Annotations can be generated in over 20 citation styles directly from the reader, aiding academic workflows. For institutional users purchasing 50 or more subscriptions, the platform provides integrations with learning management systems such as Canvas and Moodle, allowing seamless embedding of resources and tracking of student engagement within existing educational ecosystems. These features collectively aim to transform passive reading into an active, data-informed process.[50][51][52][35]

Partnerships and impact

Publisher collaborations

Perlego has established partnerships with over 9,700 publishers worldwide, enabling the platform to offer a comprehensive digital library of academic, professional, and non-fiction titles.[4] Key collaborators include major academic publishers such as Wiley, Bloomsbury, Pearson, Springer Nature, Taylor & Francis, Cambridge University Press, Elsevier, Cengage, and Routledge.[34][53][54] These relationships focus on licensing digital content for subscription-based access, with publishers retaining control over sales rights, title availability, and collection curation.[38] The core of these collaborations involves revenue-sharing licensing agreements that support unlimited access to e-books for subscribers. Under this model, Perlego allocates 65% of each subscription fee directly to publishers, providing recurring revenue based on ongoing book usage across multiple months.[38] Perlego manages digital distribution and implements anti-piracy protections to safeguard content, ensuring publishers receive fair compensation while expanding reach to price-sensitive audiences.[38][55] This structure addresses publisher priorities by offering insights into content usage and market trends without cannibalizing traditional sales channels.[22] Notable deals highlight the depth of these partnerships. In 2023, Wiley extended its agreement with Perlego, granting students unlimited access to Wiley's digital catalog alongside other publishers' titles as part of the subscription service.[34] Similarly, a 2025 partnership with MIT Press added thousands of academic titles, emphasizing Perlego's role in broadening access to prestigious scholarly content.[56] Earlier agreements, such as the 2020 collaboration with Cambridge University Press, focused on integrating digital textbooks to support student learning.[54] Since its 2017 launch with approximately 650 publishers, Perlego's partnerships have grown significantly, reaching over 5,000 by 2022 and exceeding 9,700 by 2025.[57][19][4] This expansion has been instrumental in building a library of over 1.5 million titles, enhancing content diversity and global availability.[4]

Institutional integrations

Perlego offers site licenses to educational institutions, enabling unlimited access to its digital library for students and staff through personalized subscriptions managed by administrators. These licenses include usage analytics via the platform's Subscription Manager, allowing institutions to track engagement and resource utilization.[35] The company's first major institutional partnership was with the University of West London in 2022, providing full access to over one million ebooks for all students and staff. In September 2024, Perlego expanded with the University of Leeds, granting unlimited access to approximately 40,000 users across academic and professional titles integrated into the university's library systems. A further rollout occurred with Westcliff University in early 2025, serving its 8,000 students as part of a broader digital transformation initiative.[58][59][60] Integration features support seamless adoption, including single sign-on (SSO) for secure access using institutional credentials, embedding within learning management systems (LMS) like those at the University of Leeds, and tools for custom course reserves through reading list compatibility. Pricing for these site licenses is structured on a sliding scale based on student enrollment, with personalized proposals available for larger implementations exceeding 50 subscriptions.[35][61][32] By 2025, Perlego had partnered with over 250 institutions globally, initially concentrating on the UK and Europe before extending to the US, including pilots with select community colleges to broaden accessibility. These integrations have been credited with reducing institutional library costs through affordable bulk access and enhancing equity by eliminating barriers to high-quality resources for diverse student populations.[35][60]

Reception and recognition

Perlego has received positive reception for its affordability and accessibility in the educational technology sector, often likened to the "Spotify for textbooks" in a 2022 TechCrunch article that highlighted its subscription model as a disruptive alternative to expensive individual purchases.[19] User reviews on major platforms reflect this approval, with an average rating of 4.5 out of 5 on the Apple App Store based on over 1,000 reviews praising its seamless reading experience and cost savings for academic literature.[62] Similarly, as of early 2026, Perlego has a 4.6 out of 5 rating on Trustpilot from 2,432 reviews. Users praise its vast library (over 1 million titles), affordable pricing (such as plans starting around $12/month), useful features including highlighting, note-taking, text-to-speech, AI tools, cross-device sync, and responsive customer support, along with the clean interface and broad selection of titles that replace multiple $150+ textbooks.[9] On Google Play, the app scores 4.1 out of 5 from 1,864 reviews, with users noting its value in enabling access to essential resources without financial strain.[63] Criticisms of Perlego center on its subscription-based access, which provides no permanent ownership of content, leading some users to express concerns over long-term dependency and the inability to resell or keep books post-subscription.[64] Additional feedback highlights occasional interface issues, such as buggy scrolling and limited viewing options on the app, as well as content gaps in certain regions or subjects, with one review noting reduced publisher availability in Australia as of 2020.[9] Common criticisms also include difficulties with subscription cancellation, occasional unexpected or recurring billing charges, limited functionality on some licensed titles (such as restrictions on highlighting, annotation, or text-to-speech), and no offline PDF export in some cases. Recent reviews remain mostly positive despite these recurring billing and cancellation concerns. While the platform offers an offline reading mode to address internet dependency, reviewers occasionally mention challenges in remote or low-connectivity areas.[65] Perlego has earned several awards and recognitions for its innovations in edtech. It was named a winner in the World Future Awards for removing financial barriers to educational resources through its unlimited access model.[66] In 2024, the company was shortlisted for The Stationers' Company's Innovation Excellence Awards, acknowledging its contributions to publishing and technology integration, and won the Start-up Award with a merit in the EdTech category.[67] Earlier, in 2019, Perlego received the Best Edtech award at TechCrunch's Europas, celebrating its early growth in digital learning tools.[11] It also participated in the Founders Factory edtech accelerator program in 2018, backed by Holtzbrinck Publishing Group, which supported its expansion across Europe.[17] In January 2025, Perlego was listed in the Sunday Times ranking of the 100 fastest-growing technology firms in the UK. The platform's impact extends to broader discussions on educational equity and open access, with investments like ITHAKA's 2024 commitment underscoring its role in reducing student expenses and enhancing convenience through digital libraries. Since its inception, Perlego has raised over $90 million in funding as of 2025, including a $50 million Series B round in 2022 led by Mediahuis Ventures, Raine Ventures, and Evli Growth Partners, and a $20 million round in 2024 led by former Tesco CEO Sir Terry Leahy, fueling expansion and technological improvements.[68][69][5][70] During the COVID-19 pandemic, Perlego pivoted by offering free subscriptions to meet surging demand for online materials, facilitating a shift toward digital learning and contributing to cost reductions estimated at up to 20% for users based on company analyses of textbook alternatives.[71] This has positioned Perlego as a key player in post-pandemic edtech, promoting discussions on sustainable access models over traditional ownership.[22] Looking ahead, Perlego announced plans in 2024 to expand globally and integrate AI-driven tools, supported by a $20 million funding round led by former Tesco CEO Sir Terry Leahy, aiming to enhance research assistants and reach more international learners and institutions.[70]
