Company profile
researched Aug 2026Realeyes is a Vision AI company that began at Oxford University in 2007 and was, by its own account, the first company to measure users via webcams across the internet at scale. Its original business measured emotional response and attention of consumers watching video content through ordinary mobile or desktop webcams, allowing brands, agencies and media companies to quantify and optimise creative effectiveness and inform media buying. Over time the company extended the same computer vision and machine learning base into human verification, marketing its VerifEye technology for face liveness detection, face matching, deepfake verification and age/gender estimation.
The current positioning is around proving that a real, unique human is behind a post, payment or profile, so that platforms can authenticate users, prevent fraud and maintain trust as bots, deepfakes and AI agents proliferate. The company states it applies Responsible AI practices dating to the consent frameworks built for webcam-based attention measurement, and that this produced a large GDPR-compliant, in-the-wild video dataset used to train its verification, age estimation and deepfake detection models. In 2025 Realeyes spun out its advertising creative measurement business as a separate company, Adverteyes, which continues the attention, emotion and sales-prediction product line for advertisers.
Founding story
Realeyes started at Oxford University in 2007, co-founded by Mihkel Jäätma and Elnar Hajiyev, who was completing a fully funded PhD in computer science at Oxford focused on database structures, together with Martin Salo. Jäätma pursued emotion analytics before large-scale consumer data analysis was commonplace; Hajiyev had previously co-founded Semmle during his doctorate before joining Realeyes.
Business model
Realeyes licenses Vision AI models and an SDK to enterprises and consumer applications, positioning itself around handling strict legal requirements, heavy technology stacks and hyper-scale deployment volumes. Historically it also sold webcam-based ad and content testing to brands, agencies and media companies, a line that has been placed in the separate Adverteyes business.
Traction
The company reports its SDK executes over 1 billion calls per day and that it runs at over 100 billion verifications annually, with a dataset built from more than 18 million webcam sessions.
Latest developments
Realeyes announced the spin-out of Adverteyes, a separate creative intelligence company for advertising effectiveness measurement, and continues to develop the VerifEye human verification line. Executive listings record advisor appointments in January 2026. The company states it has moved from venture funding to being self-funded.

Market position
The company positions itself as aiming to become the global standard for human verification, and states its SDK call volume exceeds that of any other biometric or Vision AI company. In advertising, its attention and emotion metrics have been integrated by Nielsen as part of an outcomes measurement marketplace.
Realeyes cites its consent frameworks and Responsible AI practices developed for webcam attention measurement, and the resulting large GDPR-compliant real-world video dataset, as the basis for its verification and age estimation model accuracy, alongside operating scale in daily SDK calls.
Technology
Realeyes builds computer vision and deep learning models that operate through standard mobile and desktop webcams. The VerifEye product line covers face liveness detection, face matching, deepfake verification and age and gender estimation, with documentation for multiple platforms. Models are trained on what the company describes as the industry's largest GDPR-compliant, in-the-wild video dataset, drawn from over 18 million webcam sessions. The company's SDK is stated to execute more than 1 billion calls per day.
Go-to-market
Sales are directed at enterprise platforms and consumer apps through direct business development and partnerships, supported by developer documentation for SDK integration. In the advertising segment the company has gone to market through measurement partners and integrations, including Nielsen's outcomes marketplace and creative analytics partners.
Large enterprises and consumer applications with demanding legal, scale and technical requirements, including platforms needing user authentication and fraud prevention. In its advertising measurement business, customers have included brands such as Mars, AT&T, Hershey's and Coca-Cola, agencies including Ipsos, MarketCast and Publicis, and media companies such as Warner Media and Teads.
Geography
Headquartered in Europe, with a registered London address at 5 New St Square, Holborn.

It describes long-standing partnerships with US technology companies and strategic investment from Japanese corporates.
History
The company was founded in 2007 at Oxford University by Mihkel Jäätma, Elnar Hajiyev and Martin Salo. It built webcam-based emotion and attention measurement for the advertising industry, raising venture funding including a $12.4 million round in 2019 to expand into Japan and a later $16 million growth round. Cumulative venture funding reached $45 million, after which the company describes itself as self-funded. Realeyes shifted its core focus to human verification under the VerifEye brand, and announced the spin-out of Adverteyes as a standalone creative intelligence company.
