Why we invested
In a market where no one can build a data moat — law firms will never let a vendor train on privileged work product — we argued that being the institutional default is the moat. We published that thesis in September 2025; an a16z-led $160M round in Harvey was reported five weeks later.
The argument was that brand compounds in legal the way network effects compound elsewhere: each white-shoe firm that signs makes the next one likelier. It followed that Harvey's low day-to-day usage at many firms was not the problem it looked like — in a vertical running on trust and patience, being installed and unlikely to be ripped out beats being heavily used.

2022
A cold email on the Fourth of July.
Winston Weinberg, then a first-year litigation associate at O'Melveny & Myers, and his roommate Gabe Pereyra tested GPT-3 on landlord-tenant questions pulled from Reddit. According to TechCrunch's account, two of three practicing attorneys said they would send 86 of 100 answers with no edits. They emailed Sam Altman on 4 July 2022, spoke with him that morning, and took their first check from the OpenAI Startup Fund.
