About
Avvoka is a UK-based legal technology company that has built an AI-powered contract drafting and negotiation platform for law firms and corporate legal departments. Founded in London, Avvoka addresses one of the most time-consuming workflows in legal practice: the drafting, redlining, and negotiation of complex commercial contracts. The platform allows legal teams to automate template-based drafting, collaborate on contract negotiations in real time, and use AI to accelerate review and markup — reducing the time lawyers spend on high-volume, lower-complexity contract work.\n\nThe platform is designed for both law firms and in-house legal teams, with tools that support the full contract lifecycle from initial drafting through execution. Avvoka's AI layer can generate first drafts from structured questionnaires, suggest clause language, identify non-standard terms, and flag risk. Its collaboration features allow multiple parties — including opposing counsel — to work within the platform, reducing the back-and-forth of email-based redlining. The platform is particularly well-suited for high-volume contract types such as NDAs, service agreements, and commercial leases.\n\nAvvoka raised £14M in March 2026 to accelerate product development and expand its presence in the US and European markets. The company's most notable commercial milestone is adoption by 20%+ of Am Law 100 firms — the 100 highest-grossing law firms in the United States — a penetration rate that signals strong product-market fit at the top tier of the legal market. This level of adoption among elite law firms provides both revenue credibility and a reference base that is highly persuasive to corporate legal departments evaluating contract AI vendors.
