London-based stealth startup 22one has raised an undisclosed funding round from Sequoia, General Catalyst, Lux Capital and Creandum at a reported valuation of almost $400m, according to the Financial Times. The company plans to build AI tools for police forces, but neither 22one nor the investors confirmed the report, and no lead investor, ownership terms or use-of-funds plan was disclosed.
The valuation is not the amount raised. It is a reported company valuation attached to a round whose size remains undisclosed.
Police AI is moving from local pilots to a national buying programme
22one has not publicly described a product beyond its law-enforcement focus. Its founder, Steven Richardson, does bring operating history in the same customer base: after senior policing roles and work at AWS and Palantir, he co-founded Riven, whose DocDefender software automates redaction of sensitive information in police documents. Hill Dickinson said the product was used by nearly half of UK police forces when Riven was sold to NEC Software Solutions in 2024. A College of Policing case study reported 92% accuracy in a controlled Bedfordshire Police pilot.
Those results belong to Riven, not 22one, but they help explain the financing logic. Police software is sold into a market where access to users, evidence from controlled trials and confidence in handling sensitive data can matter as much as model capability. Richardson has previously taken one narrow administrative workflow from pilot to multi-force adoption. Investors are backing the possibility that he can repeat that path across a broader set of policing tasks.
The addressable route is becoming more organised. The Home Office launched PoliceAI in June with £75m over three years and plans to pilot tools for digital-evidence triage, disclosure and summarisation in up to 10 forces during 2026-27 before wider scaling in 2027. That creates a national testing and procurement channel, but not an automatic customer base. PoliceAI also plans independent checks for accuracy and bias and a public registry of deployed tools.
For 22one, the commercial test is therefore unusually concrete: turn founder credibility and investor backing into a product that survives formal evaluation, procurement and public scrutiny. A near-$400m reported valuation prices in that outcome before the company has disclosed a product, customer or deployment. The next meaningful milestones will be named pilots, measurable performance and governance evidence rather than another valuation headline.
