When one of the UK's most successful law firms needed AI built right, they called East Agile
Keystone Law isn't just any firm. It's listed on the London Stock Exchange, posted £115.2m in revenue last year (up 18%), has 650+ fee earners, and has more than 220 of its lawyers ranked in the Legal 500. It's widely seen as the UK's premier tech-enabled platform law firm, and it's leading the profession's adoption of agentic AI.
This week Keystone launched Origin, an AI-powered source-of-funds enquiry tool East Agile built with Keystone's technology team.
The problem
Anti-money-laundering rules require lawyers to ask clients where their money comes from. Those conversations are uncomfortable, inconsistent, and depend heavily on individual judgment.
How Origin solves it
Clients get a guided digital enquiry that understands their situation: money from a house sale, an inheritance, funds held in a spouse's name. It asks for exactly the right evidence and turns it all into a clear, documented report for Keystone's compliance team, who keep the final judgment.
Keystone's IT Director Maurice Tunney put it perfectly:
It "solves an existing problem using technology in the right way."
Why it matters to us
That's what we've built East Agile on since 2007: AI that works inside regulated, high-stakes environments, alongside the experts who own the outcome.
