Yoti bets UK Online Safety Act makes age checks mandatory — and its app tops the App Store
Digital identity startup founded 2014; when UK Online Safety Act age checks took force in July 2025, its app hit 6M+ downloads and #1 on the App Store.
Yoti
What the business is
Digital identity and age assurance: a free app plus facial age estimation and document verification that businesses pay to integrate into age-gated online services.
Starting capital：£16M equity across two rounds by 2019 (post-money £82M), with earlier rounds funded mostly by founders.
How it started
Robin Tombs, an ex-online-gambling executive, co-founded Yoti in London in 2014 with the thesis that proving age and identity online would soon be a legal requirement. The free app let users verify once and share only the minimum attribute; by August 2019 it had 4.7M downloads and £16M in equity funding at an £82M valuation, with early partners including Heathrow, NCR and Yubo.
What happened
Yoti spent years selling age assurance to social platforms (Meta, TikTok) and running official trials, positioning itself for the UK Online Safety Act. Ofcom's age-assurance duties took force on July 25, 2025, requiring sites that host adult content to prevent children accessing it, with fines up to £18M or 10% of qualifying worldwide revenue. By July 15, 2025 Yoti's app had been downloaded more than 6 million times; it briefly hit #1 on the Apple App Store, and its facial age estimation scored the top Technology Readiness Level (9) in Australia's Age Assurance Technology Trial.
How it ended up
Still running and scaling: Yoti has become default age-assurance infrastructure for UK compliance, with the Online Safety Act enforcement wave behind its biggest growth spike.
Background
Yoti is a London digital identity company founded in 2014 by Robin Tombs, an ex-online-gambling executive, and Duncan Francis. Its free app lets people verify their identity once and then share only the minimum attribute — such as an 'over 18' result — with websites and businesses, which pay for the verification. By 2019 it had 4.7M downloads, £16M of equity funding and an £82M valuation.
The founding bet was that proving age and identity online would eventually be a legal requirement, not a choice. Yoti spent years attaching its technology to the most regulation-sensitive spots: age checks for social platforms like Meta and TikTok, airport travel, and self-checkout alcohol sales. The catalyst arrived on July 25, 2025, when Ofcom began enforcing the UK Online Safety Act's age-assurance duties — adult-content sites had to prevent children accessing harmful material, with fines up to £18M or 10% of qualifying worldwide revenue.
The mandate turned Yoti from a long-term positioning play into a compliance utility. By mid-July 2025 its app had been downloaded more than 6 million times and briefly reached #1 on the Apple App Store; its facial age estimation scored the highest Technology Readiness Level in Australia's Age Assurance Technology Trial. As enforcement began, Yoti's CEO called the download spike 'completely flabbergasting' — but the underlying bet was the decade-old one: regulation would make age assurance infrastructure.
What has to be true
- Yoti was built around the regulatory thesis from day one: age and identity verification would become legally required, and the provider ready when the law landed would own the market.
- The OSA turned voluntary age checks into mandatory duties, creating a compliance category platforms cannot ignore, with fines up to £18M or 10% of revenue.
- Yoti had the proof points regulators look for: years serving Meta and TikTok, and the top Technology Readiness Level score in Australia's official age-assurance trial.
- The app-led model created consumer pull — 6M+ downloads as enforcement began — while real revenue comes from business-to-business verification fees.
What can be applied
A startup can sell the same product for a decade before the regulatory catalyst lands — the value is in being the proven, trusted option when a mandate turns optional demand into compulsory demand.
Aftermath
As of September 2026, Yoti is the UK's most visible age-assurance provider, riding the Online Safety Act enforcement wave that began in July 2025. App downloads exceeded 6 million around the deadline and briefly hit #1 on the App Store; Meta and TikTok remain clients. It sells reusable digital ID, facial age estimation and document verification across the UK, Europe and Australia, citing the Australian trial's top readiness rating. Its model — charging businesses, never users, deleting facial images after estimation — is built to withstand privacy scrutiny of age-verification laws.
