From Product to Practice: Why Casetext's Former CTO Has Started An AI Native Law Firm

As chief technology officer at Casetext, Ryan Walker helped build CoCounsel, one of the first and most consequential generative AI legal assistants — a product so significant it led to the company's $650 million acquisition by Thomson Reuters. But Walker came away unsatisfied. Although the legal tech tools kept getting better, he believed, clients were seeing no benefit. Billing rates kept climbing and the efficiency gains never reached them. That spurred him to pivot from building products to forming a practice — General Legal, an AI-native law firm he cofounded and leads as CEO, built on the premise that the fastest path to transforming legal services is not retrofitting AI onto traditional firms, but rebuilding the law firm from the ground up on an AI-forward foundation. Just six months out of Y Combinator, the firm has some 400 clients, a newly launched venture financing practice, and, in what may be a first for a law firm, an MCP server that lets clients' AI agents engage the firm directly. In this episode of LawNext, Walker — not a lawyer but a PhD mathematician — tells host Bob Ambrogi why he believes AI can now automate 95% of routine legal work, how the management services organization structure allows an investable technology company to operate alongside a law firm, and why an AI-native firm paradoxically depends on hiring highly experienced lawyers rather than supercharging junior ones. He also explains the "second brain" approach that lets the firm's work product reflect each client's strategy, what earlier failed innovators like Atrium and Clearspire got wrong, and why he thinks the real reckoning will come when major clients simply refuse to pay for work AI can do. Walker cofounded the firm along with two other Casetext colleagues, Javed Qadrud-Din, who was head of AI at Casetext and is now General Legal's chief technology officer, and J.P. Mohler, who was an LLM engineer at Casetext and is now chief product officer and managing partner. Their ultimate ambition, Walker says, is to make General Legal the biggest provider of legal services in the world and, along the way, to break the scarcity model that keeps legal help out of reach for the people and companies who need it.   Thank You To Our Sponsors This episode of LawNext is generously made possible by our sponsors.
