Company profile
researched Aug 2026Kinnu (Kinnu Ltd., kinnu.xyz) is a London-based education technology company that builds consumer learning products underpinned by an AI-driven 'learning engine'. The company frames its objective around a self-defined metric it calls Time To Mastery (TTM), which it aims to reduce toward zero using tools drawn from cognitive science, memory research and motivational/behavioural design. Its internal engine, named 'Maia', is described as predicting when a learner will forget material and adapting content to attention level.
The product line has two branches. Kinnu General Knowledge (also presented as the 'Kinnuverse') offers free bite-sized 'pathways' across categories such as culture, history, lifestyle, philosophy, psychology, science and technology, with topics including quantum mechanics, macroeconomics, Norse mythology, astronomy, dinosaurs and AI; lessons are short read-or-listen modules followed by multiple-choice questions, with spaced repetition delivered through a feature described as 'Memory Shield'. Kinnu Exam Prep is a paid-market-oriented set of dedicated products for the Solicitors Qualifying Examination (Kinnu Law, mobile in May 2025 and web in October 2025), the CFA (February 2026) and the SAT (July 2026), combining MCQ banks, flashcards, study notes, performance statistics and an exam-specific AI assistant.
Content production combines human and generative AI steps: human experts define a course outline or pathway, which is passed to large language models that identify core ideas and generate revision questions in formats such as multiple choice. The company positions itself against a framework of 'content, access, and learning product', arguing content is commoditised by AI and that the remaining frontier is the learning product itself.
Founding story
Kinnu was founded in July 2021 (press coverage says 2021) by Christopher Kahler, Abraham Muller (Müller) and Hanna Celina. Kahler and Muller had previously founded the real-time market research startup Qriously, backed by Accel and Spark, which was sold to Brandwatch in early 2019 for an undisclosed sum; during their post-acquisition sabbatical they returned to a shared interest in learning, and a former investor introduced them to Hanna Celina, who studied at Harvard, holds a PhD in human-computer interaction design focused on social online learning from Newcastle University, and previously worked at Google, Deliveroo and FutureLearn. Early work took place in Kahler's garage in Hackney, London. The company describes its conceptual origin as a scene in The Matrix in which Neo learns kung fu via direct upload [0][4][5][7].
Business model
Kinnu distributes mobile and web learning applications directly to individual learners. The general-knowledge app is described by a third-party review as free to download and use on iOS and Android, with users reporting no ads, subscriptions or paywalls as of July 2026, while the newer exam-prep products (SQE, CFA, SAT) target candidates preparing for specific professional and admissions examinations [2][0].
Sources do not state how Kinnu monetises; the general-knowledge app is described as free with no ads or subscriptions [2].
Traction
The company's website reports 1.2 million users, 3.2 million hours learned and 90 million question sessions. Kinnu: Superpower Learning (March 2022) surpassed 500,000 installs; Kinnu 2.0 (February 2024) surpassed 1.2 million installs. Kinnu Labs, launched September 2024, ran with over 10,000 participants and, per the company, showed Kinnu outperforming 1:1 in-person human tutors in high-school-level physics and history. For Kinnu Law mobile, the company states 20% of exam takers within eight weeks used it more than one hour per day, with 3,000 practice MCQs available [0].
Latest developments
Most recent milestones on the company timeline are the launch of Kinnu CFA Prep (February 2026), a platform for CFA Level I candidates, and Kinnu SAT Prep (July 2026), which added SAT coverage alongside an overhaul of the product's Study Notes. A third-party review published in July 2026 describes the general-knowledge app as still free on iOS and Android [0][2].

Market position
Kinnu operates in consumer edtech / microlearning. A competitor's review blog characterises it as one of the more talked-about bite-sized learning apps, praising its low barrier to entry, clean interface, topic variety and grounding in spaced repetition and active recall, while criticising weak habit-formation mechanics, limited format variety and shallow progression [2]. Coverage of its 2023 round positioned it as attempting to shift edtech value away from content toward the technology of knowledge acquisition and retention [6][7].
The company argues that content and access are largely solved or commoditised in an AI era and that the differentiating layer is the 'learning product' — the behavioural and cognitive mechanisms that get knowledge into memory. It describes a deliberately gamified engine informed by behavioural design rather than superficial gamification, geospatial 'map' depiction of knowledge, and interdisciplinary pathways. Its investor LocalGlobe cited AI-driven interdisciplinary learning that lets people connect different areas as a specific attraction [4][7].
Technology
Kinnu's stated core asset is a learning engine, internally named 'Maia', intended to reduce 'Time To Mastery' by predicting forgetting curves, adapting content to attention level and applying spaced repetition and active recall. Content creation uses a three-step pipeline in which human experts build a pathway outline, large language models extract the main idea of each unit and generate revision questions in formats such as multiple choice, and the resulting courses are delivered through the app. A spaced-repetition feature is marketed as 'Memory Shield', which reintroduces concepts a learner struggles with sooner and mastered concepts less often. The exam-prep products include a bespoke SQE-specific AI model for answering candidate questions [0][2][4][6].
Go-to-market
Direct-to-consumer distribution via free iOS and Android apps and a web product, with growth driven by app installs and user reviews; the general-knowledge app reported over 500,000 installs after the 2022 launch and over 1.2 million after Kinnu 2.0, and the company ran 'Kinnu Labs', a virtual learning lab with more than 10,000 participants, to test learning features. Vertical exam-prep apps were then launched into specific credential markets [0].
Adult and general learners — students, working adults and self-directed curious learners — for the free general-knowledge product, plus candidates preparing for the SQE, CFA Level I and SAT for the exam-prep products [0][2].
Geography
Headquartered in London, United Kingdom; products are distributed globally through iOS and Android app stores and the web [2][6][7].
History
Founded July 2021; raised a pre-seed round announced January 2022 (reported as $2.5m by the company and $2.4m by Tech.eu); launched the free Kinnu: Superpower Learning app in March 2022; raised a $6.5m seed round announced July 2023 (dated March 2023 on the company timeline); launched Kinnu 2.0 in February 2024 and Kinnu Labs in September 2024; launched Kinnu Law mobile for the SQE in May 2025 and Kinnu Law web in October 2025; launched Kinnu CFA Prep in February 2026 and Kinnu SAT Prep in July 2026. Total raised is stated as approximately $9 million [0][6][7].
Risks & controversies
A review published by Nibble, a competing microlearning app, criticises Kinnu for lacking a strong habit system, making it easy to skip days, offering limited format variety, producing progress that can feel shallow without application, and creating decision fatigue given many topics without guided progression; the piece is promotional for the reviewer's own product. Several traction and efficacy claims — including outperforming 1:1 human tutors and usage statistics — are self-reported by the company and not independently verified in the sources [0][2].
