Scaling Legal AI and Building Next-Generation Law Firms with Harvey Co-Founder and President Gabe Pereyra
In just over three years, Harvey has not only scaled to nearly one thousand customers, including Walmart, PwC, and other giants of the Fortune 500, but fundamentally transformed how legal work is delivered. Sarah Guo and Elad Gil are joined by Harvey’s co-founder and president Gabe Pereyra to discuss why the future of legal AI isn’t only about individual productivity, but also about putting together complex client matters to make law firms more profitable. They also talk about how Harvey analyzes complex tasks like fund formation or M&A and deploys agents to handle research and drafting, the strategic reasoning behind enabling law firms rather than competing with them, and why AI won’t replace partners but will change law firm leverage models and training for associates.

Today’s show:
Find out why AI is perfectly suited to legal tasks… despite being too fast for “billable hours”
On today’s TWiST, Alex takes a deep dive into LLM Law with Harvey AI co-founder/president Gabe Pereyra. It turns out, much like software development, doing legal work relies on learning specialized language and sifting through a dense and expansive corpus of information… making it an IDEAL use case for LLMs.
Buuuuut AI works so fast… the current structure of legal payments (billable hours) no longer applies. Find out how Harvey is working around these challenges — and what they plan to do if OpenAI decides to get into the legal game — in this fascinating interview.
THEN, Alex chats with another AI visionary — OpenRouter co-founder and CEO Alex Atallah — who allows developers to plug and play all the major models into their applications. Find out why specialized LLMs trained for “resourcefulness” are coming into fashion… why benchmarks and evals have become so crucial to the industry… AND whether we’ll end up spending as much on AI inference as the human workers it’s replacing… in this essential discussion.
PLUS Jason stops by for some more Founder Q’s!
