Crosby, a New York-based AI-powered agentic law firm, has raised $60M in Series B funding co-led by Lux Capital and Index Ventures. The hybrid service delivers Big Law quality contract reviews for MSAs, DPAs, and NDAs in hours using AI agents with lawyer oversight, fixed per-document pricing, and malpractice insurance. The capital will fuel AI R&D and scaling to serve more high-growth sales teams.
Legal AI Series B Wave Builds
The raise follows a flurry of legal AI investments. Harvey secured $200M at an $11B valuation just days prior in March 2026, while Lawhive raised $60M Series B in February 2026 and GC AI a $60M Series B at $555M valuation in November 2025. Crosby's hybrid model targets sales acceleration, differentiating from pure AI platforms. This cluster signals VC conviction in AI reshaping legal workflows.
Billable Hours Block Deal Velocity
Traditional law firms' billable hour model delays sales contracts by weeks, bottlenecking high-velocity tech teams. Crosby clients like Ramp, Cursor, and Cognition face exploding deal volumes amid AI startup booms. The firm has reviewed 13,000 contracts with 400% revenue growth since October 2025, per Forbes coverage. Median turnaround hit 58 minutes, slashing time-to-signature.
Hybrid Agents Redefine Contract Reviews
Crosby deploys multi-agent AI systems for parallel analysis and negotiation simulations, backed by elite lawyers from Kirkland & Ellis and Sullivan & Cromwell. Unlike software-only tools, it offers liability guarantees and fixed pricing at $250-$1,000 per contract. Clients report 50% faster processes, as with Cursor's 2,000 contracts.
As CEO Ryan Daniels told Forbes:
"This is I think the most dramatic change for lawyers in a hundred years."
Execution Layer Tops Legal Tools
The agentic architecture creates a data flywheel from real negotiations, improving accuracy over time. This positions Crosby as execution infrastructure versus point solutions like Ironclad's CLM. Early traction includes $1B in contract value negotiated, up from $30M at stealth exit 283 days prior, according to the company announcement.
Tier-1 AI VCs Double Down
Lux Capital and Index Ventures co-led at a $400M valuation, with Sequoia, Bain Capital Ventures, Elad Gil, and 01 Advisors joining. Lux's bets on Cognition and Applied Compute mirror Crosby's enterprise AI agents, while Index backs Scale AI and Fireworks for legal execution fit. Sequoia's follow-on underscores category leadership potential.
Legal AI Market Scales Rapidly
The legal AI market stands at $1.45B in 2024, projected to reach $3.9B by 2030 at 17.3% CAGR, per Grand View Research. AI contract analysis tools hit $4.3B TAM in 2026, growing at 29.4% CAGR to $12B by 2030, according to Research and Markets. Trends favor hybrid models amid generative AI adoption doubling to 52% in corporate legal departments.
Penn Law Ex-Ramp Duo Leads
Co-founders Ryan Daniels (Stanford JD, ex-Bain EIR, A.Team GC) and John Sarihan (ex-Ramp product leader, Penn M&T) blend legal ops and fintech scaling expertise. Daniels handled Fortune 500 contracts at A.Team ($60M raised), while Sarihan built Ramp Travel. Big Law directors from Freshfields and Simpson Thacher bolster execution.
AI R&D and NYC Hiring Accelerate
Post-Series B, Crosby plans counterparty response simulations, voice negotiation agents, and client oversight platforms. Aggressive NYC hiring targets staff engineers ($220k-$300k) and product designers ($210k-$270k) to build the platform, signaling national expansion via hypergrowth clients.
