Winston Weinberg: Speed, Stress, and Better Decisions
The Knowledge Project
Origins: Testing GPT‑3 on Legal Questions
Winston recounts experimenting with GPT‑3 on landlord‑tenant questions and the 86/100 lawyer validation that launched Harvey.
Winston Weinberg is the CEO and co-founder of Harvey, the AI platform built for the legal industry.
In this episode, Winston explains how AI is reshaping legal work, why judgment becomes more valuable as routine work gets automated, and how to build the prioritization muscle required to move faster, stay focused, and make better decisions when everything is changing.
He also shares the operating principles behind Harvey’s growth: make decisions faster, treat most choices as two-way doors, use stress to build resilience, prioritize the one thing that matters most and the Google Doc that drives it all.
Harvey began with a simple test: take real legal questions, run them through GPT-3, and ask experienced lawyers whether they would send the answers with zero edits. On 86 out of 100 questions, three out of three attorneys said yes.
This is a conversation about AI, law, speed, resilience, and building in a world where the bar keeps getting higher.
