Today, they still share that same apartment, but their company has grown into a global enterprise serving more than 1,000 law firms and corporate legal departments and valued at a whopping $8 billion.<\/p>\n<p>In this episode of LawNext, Pereyra and Weinberg take us back to Harvey\u2019s earliest days, when they were sending thousands of LinkedIn messages trying to get anyone to look at their product. They share the pivotal moment when early access to GPT-4 transformed what they could build, the breakthrough that came when Allen &amp; Overy became their first major client, and how they have evolved from building an AI assistant for individual lawyers to constructing what they call \u201cessential infrastructure\u201d for legal work.<\/p>\n<p>With host Bob Ambrogi, they discuss Harvey\u2019s vision for becoming an AI operating system that integrates across the entire legal tech ecosystem, their focus on memory and agentic AI that can handle complex multi-step workflows, and the massive infrastructure challenges of deploying AI at scale across global law firms while maintaining ethical walls and data security.\u00a0<\/p>\n<p>Pereyra and Weinberg also reflect candidly on how two founders with no management experience have learned to scale a company now employing hundreds of people \u2014 more than 20 percent of whom are lawyers \u2014 and what it is like to go from struggling startup to being featured in <i>The New York Times<\/i> as AI billionaires while still sleeping on a mattress on the floor.<\/p>\n<p><em><strong>Listen here:<\/strong><\/em><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/8UiRcq1hpdM?si=10Ywk9jrEL04PnWS\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"> <\/iframe><\/p>\n<h3>Thank You To Our Sponsors<\/h3>\n<p>This episode of LawNext is generously made possible by our sponsors.
