Harvey
Part of the Hargora platform.
AI-powered legal assistant for professional workflows
What it is
Overview
Harvey is a generative AI platform built specifically for legal professionals. Founded in 2022 by Winston Weinberg (CEO) and Gabriel Pereyra (President), the company emerged from a cold-email to OpenAI leadership and has grown rapidly to an $11B valuation as of March 2026.
Key Features
- Legal Research — AI-assisted case law research with LexisNexis integration
- Contract Review — Automated analysis and redlining
- Brief Drafting — AI-generated first drafts with citations
- Vertical Workflows — Specialised templates (e.g., pharmaceutical antitrust defences)
- Ethical Walls & Governance — Firm-level data isolation and access controls
- APIs & MCP Support — Custom integrations via Model Context Protocol
Team Composition
Approximately 20% of Harvey’s staff are lawyers working alongside engineers — a deliberate approach to building domain-specific AI rather than adapting general-purpose tools.
r/legaltech AMA (December 2025)
Harvey’s cofounders conducted the third vendor AMA on r/legaltech in December 2025. The session ran over two hours and covered:
- Valuation: Weinberg stated “We need to earn that valuation every day”
- Competition: Addressed positioning against LexisNexis, Westlaw, and emerging competitors
- Employee Criticism: Responded to anonymous claims about weak engagement and average technology
- Growth: Reported 81% increase in daily active users since 2023 launch
The AMA received mixed reception. The community appreciated the direct engagement but noted some questions received evasive answers.

Market Context
Harvey reports $190M ARR as of end-2025, with over 100,000 lawyers across 1,300 organisations using the platform. Clients include a majority of the AmLaw 100, over 500 in-house legal teams, and 50 asset management firms across 60 countries.
The legal tech market represents only ~3% of the $1 trillion total legal services sector. Harvey’s bet is on massive technology penetration growth, targeting the estimated 10 million global legal professionals.
