AI-Generated Summary
Key Takeaways
- ✓Legal AI Evolution: Harvey transitioned from individual lawyer productivity tools to team-based workflow systems, focusing on making entire law firms more profitable by solving orchestration, governance, and enterprise integration problems rather than just model intelligence challenges.
- ✓Forward Deployed Engineering: Harvey launched a forward deployed engineering program to customize implementations for Fortune 500 clients like Walmart and AT&T, connecting AI systems to billing, governance, and document management systems that lack standardization across large enterprises.
- ✓Training Future Partners: Law firms face a structural challenge as AI reduces associate headcount needed for leverage ratios, requiring new approaches to identify and develop future partners when fewer junior lawyers gain hands-on experience with complex transactions over time.
- ✓Reinforcement Learning Challenges: Legal work lacks the verifiable unit tests that make coding suitable for RL training. Harvey addresses this by using partner feedback and edit histories from completed matters as reward signals, similar to how senior engineers validate system architecture.

Notable Moment
Pereyra reveals that major mergers like Microsoft-Activision involve 100 outside counsel firms because each jurisdiction requires specialized expertise, such as understanding New Zealand tax implications, demonstrating the massive scope and complexity of enterprise legal operations.
Episode Transcript
Gabe, thanks for doing this. Of course. Yeah. Thanks for coming. Maybe we can just start with, like, for anyone who hasn't heard of Harvey, what is the company? Can you talk about the scale and who you serve today? At Harvey, we're building AI for law firms and large in house teams. We're almost at a thousand customers, 500 employees. Started about just over three and a half years ago and so been kind of scaling quickly since then and kinda you guys were some of our OG seed investors. So, yeah, good to be here. Maybe from a most basic perspective on the product, why is it not just, you know, CoPilot or TouchPT or Claude? Yeah. I think that's how the product started. So when we first raised from OpenAI, we got access to GPD four, and I think GPD three to GPD four was such a big model jump that the intuition at the time was just give the model to lawyers and have them play with it. And I think that industry was so text heavy that you got so much value from just interacting with the models. And then I think as soon as you gave it to lawyers, you also ran into all of the sharp edges of the models of they hallucinate, they're not connected to a bunch of our context. And so I would say the past, the kind of first two years of the company were how do we build essentially the IDE for lawyers around these models that connect it to all of the context you need to be productive as an individual lawyer. But I would say in the past year and going forward, the big problem we're solving is not how do you make individual lawyers more productive, it's how do you make a team of lawyers working on a client matter more productive, and more importantly, how do you make an entire law firm working on thousands of these client matters more productive and more profitable? And so I think when you get to that scale, a lot of the problems you're solving are not just model intelligence problems. They are these orchestration, governance, and kind of all of the enterprise product problems that you run into at at scale. You've also been broadening from just law firms into enterprises, into big companies using you in concert with both their in house legal teams and external, counsel. Can you talk more about that and how that's been evolving as well? Yeah. So we started selling to the largest law firms and something that had started happening about a year and a half ago was these law firms started showing Harvey to their clients and their clients both wanted to collaborate more effectively with their law firms and they also wanted to use this directly in their in house department. So we recently announced, we signed Walmart, we're working with AT and T, a bunch of these …
