In this episode, Winston walks me through Harvey’s San Francisco HQ and then sits down to break down the state of the business:
Reaching nearly 2,000 customers (now 3,500!)
Scaling to 960 employees across 12 global offices
How token usage jumped from 1 trillion in January to an est. 13 trillion in June
“If you don’t constantly change, you are gonna get so behind that you die as a company right now.”
Winston covers the shift to cloud agents, why Harvey’s real competition is the foundation labs (not other legal tech companies), how to reinvent a company every 6 months, the future of vertical models, the billable hour problem coming for every AI buyer, and why every company will eventually sell intelligence.
Valued at $15 Billion, Harvey is on a mission to win the entire legal category, competing head-on against the trillion-dollar labs.
And they’re well on their way. This month, Harvey has passed $400M ARR, 960 employees, 3,500 customers, and roughly 13 trillion tokens processed. They’ve raised $1.5B to date from Sequoia, Kleiner Perkins, GV, Coatue, Elad Gil, the OpenAI Startup Fund, and GIC.

What’s next for the open-source legal research community
Coding agents hit Karpathy’s “agents work now” inflection in late 2025. Gabe argues legal is hitting its version of that curve right now.
Just a few weeks ago, Harvey open-sourced LAB, the Legal Agent Benchmark, the first open-source benchmark for measuring AI agent performance on real-world legal tasks. It covers 1,200+ tasks across 24 practice areas with 75,000+ rubric criteria, with initial leaderboard results from OpenAI, Anthropic, & DeepMind released today.
Before Harvey, Gabe was an AI researcher at Google Brain, DeepMind, and Meta, working on deep learning in 2016-2017 as the field was taking off. Niko was previously at Google Brain as well. Together, they led the open-sourcing of LAB.
This is the second episode in Sourcery’s Harvey mini-series, following the last conversation with co-founder and CEO Winston Weinberg.
