About
Winston Weinberg quit his first-year litigation job at O'Melveny & Myers at 26 to co-found Harvey in 2022, and built the legal-AI platform used by half the Am Law 100 to an $11 billion valuation in its March 2026 round co-led by GIC and Sequoia. A Kenyon College graduate with a USC Gould JD, he was shown GPT-3 by his roommate Gabriel Pereyra — a DeepMind and Meta AI researcher — and their tenant-law prototype convinced Sam Altman: the OpenAI Startup Fund anchored Harvey's seed after a cold email. PwC's global alliance made Harvey the Big Four's legal-AI platform; he preaches 're-earn your role every six months.'

Cold-emailed Sam Altman on July 4, 2022; the OpenAI Startup Fund anchored Harvey's $5M seed and the company got early GPT-4 access. PwC's March 2023 global alliance put Harvey in front of ~4,000 legal professionals in 100+ countries, later extended into a PwC–OpenAI–Harvey foundation-model partnership.
