About

Crosby is an AI-native law firm that combines experienced lawyers with proprietary AI to review, redline, and negotiate commercial contracts for startups and rapidly growing companies. Unlike software vendors that sell tools to lawyers, Crosby directly provides legal services, with human oversight, rapid turnaround, and responsibility for its work.

Market

Crosby competes in AI-powered legal services, automated contract review, and the broader contract lifecycle and negotiation market. It positions itself as a hybrid or agentic AI law firm rather than purely as software: AI agents handle pattern-rich contract work while licensed lawyers review every document, with fixed per-document pricing and turnaround measured in minutes or hours. This differentiates Crosby from CLM platforms focused on workflow and repositories, and from general legal AI tools that may require more configuration or lack mandatory attorney oversight.

Target Customers

Crosby primarily serves high-growth technology and other fast-growing businesses—especially startups without a general counsel—that need routine sales contracts reviewed quickly. Its key users and buyers include founders, sales/GTM and RevOps teams, and in-house legal leaders with high contract volume or limited legal capacity.

At a Glance

Problem

Crosby solves the contracting bottleneck that slows fast-growing companies. Commercial agreements such as MSAs, DPAs, and NDAs are often high-volume, time-sensitive, and dependent on expensive specialist review; when they sit in a legal queue, sales teams cannot close deals or recognize revenue. The pain is especially acute at quarter-end, when a delayed contract can directly impede growth.

The killer use case is rapid review and negotiation of an incoming sales contract without sacrificing legal judgment. Crosby targets the economic burden of lengthy outside-counsel processes by reducing turnaround time, avoiding dozens of hours of manual work, and helping companies save thousands of dollars while getting agreements signed faster.

Product / Service

Crosby is a hybrid, AI-first law firm rather than a software-only contract tool. Customers send a document or legal question through Slack, email, or a CLM trigger; Crosby’s agents identify and triage the matter, apply customer-specific rules, prepare initial redlines, and flag standard issues, while expert lawyers handle strategic decisions, nuance, and complex legal reasoning. Its customer knowledge base and playbooks become more tailored over time.

The service is delivered through existing deal-desk workflows, with fixed rates by document rather than hourly billing. Crosby says it can review contracts in under an hour, and its Client Console adds routing rules, dynamic playbooks, negotiation tracking, and one-click approval of suggested edits. The benefit is faster, more predictable legal support that gives growing companies greater legal capacity without requiring a large in-house team.

Market

Crosby competes in the emerging market for AI-powered contract review, legal workflow automation, and AI-native legal services. Its differentiation is the combination of legal-service delivery and proprietary AI agents with lawyers-in-the-loop, positioning it as a services-as-software or hybrid law-firm alternative to buying software alone. Adjacent competitors include LegalOn for in-house contract review, Harvey for law-firm workflows, and Spellbook for lawyers working inside Word; these products overlap with Crosby’s contract-review use case but generally emphasize software rather than Crosby’s managed legal service.

Crosby is clearly commercial rather than pre-revenue. Public evidence identifies customers including Cursor, Clay, UnifyGTM, and Listen Labs; reports also describe roughly 1,000 contracts processed every three weeks, a 58-minute median turnaround, and more than 100 customers in 2026 coverage. Crosby’s March 2026 announcement said it had raised a $60 million Series B, while another report cited approximately $1 billion in contract value negotiated. Revenue was not disclosed in the available evidence, but the customer base, contract volume, and funding indicate substantial early traction.
