Deal Velocity, Not Billable Hours: How Crosby Uses AI to Redefine Legal Contracting

In this interview Sonya Huang talks with Crosby co‑founders Ryan and John about their AI‑first law firm, which automates contract work (NDAs, MSAs, DPAs) by embedding lawyers directly alongside engineers. They explain why they chose a services‑oriented firm rather than a pure software product, emphasizing the feedback loop created when domain experts use the AI themselves. The conversation covers their pricing shift from billable hours to per‑document billing, the importance of product velocity and instrumentation (tracking turnaround time, human touchpoints, and quality scores), and the use of per‑customer fine‑tuning and evaluation to push model accuracy from 90 % to 99 %+. They detail their agent orchestration hierarchy (paralegal routing agents, junior/senior associate agents, senior partner oversight) and the technology stack built on multiple foundation‑model partners (OpenAI, Anthropic, Google). Metrics such as total turnaround time (TTAT) and human‑review time (HURT) serve as North‑Star goals, aligning incentives for both clients and the firm. The founders discuss building a culture where lawyers become prompt engineers, the New York talent and design ecosystem that shapes Crosby, and their view of which legal work can be fully automated (low‑complexity consumer contracts) versus what remains a human domain. Finally, they speculate on the next decade of the legal industry, the rise of AI‑first legal services, and advice for law students to embrace questioning, AI tooling, and apprenticeship.
