A trial lawyer watched large firms bring armies to litigation. His answer was to turn years of legal judgment into software - and give lawyers their time back.

A Stanford-trained lawyer became the executive joining GM's marketing and communications. Her career explains why the company now treats brand, reputation and business strategy as one conversation.
Brenden Prins-McKinney is the co-founder and CEO of Duranium (YC S25), an Alameda, California company working to bring critical light metal production - titanium, magnesium, aluminum, zirconium and hafnium - back to American soil. A Stanford Law graduate and Knight-Hennessy Scholar with a research background at McKinsey and a stint as a Goldman Sachs banker, he advised the Department of Defense on reshoring critical chemical production before deciding to build the supply chain himself. He pairs a policy-and-finance brain with chemistry borrowed from the 1950s, modernized so the U.S. can make metals it currently buys almost entirely from China and Russia.
Maryssa Barron is the founder and CEO of BuildQ, an AI-powered project intelligence platform for the energy sector that structures project data, automates due diligence, and accelerates clean energy financing and M&A. A Harvard graduate, Stanford-trained lawyer, and licensed D.C. attorney, she spent nearly a decade in renewable energy - pioneering early power purchase agreements and rising to COO at a global independent power producer - before building the tool she wished had existed. She founded BuildQ in 2024 while studying for the bar exam, won the 2025 AngelNV competition and over $1 million in funding, and within a year had grown the platform to 300+ projects, 10+ gigawatts of clean energy capacity, and over $150 million in deal flow.
Ryan Daniels is the cofounder and CEO of Crosby, a hybrid AI law firm that pairs licensed lawyers with proprietary AI agents to review commercial contracts (MSAs, NDAs, DPAs) in under an hour at fixed per-document pricing. A Stanford Law graduate and former startup general counsel who got tired of being the bottleneck on his own company's deals, Daniels built the product he wished he had. Since emerging from stealth in 2025, Crosby has negotiated more than $1 billion in contracts for clients like Cursor and Clay, and raised about $85.8M from Sequoia, Index, Lux Capital and Bain Capital Ventures.
Daniel Lewis is the Global CEO of LegalOn Technologies, the most well-funded AI platform for in-house contract review, having raised over $200 million. A Stanford Law grad who co-founded Ravel Law from a Stanford dorm, partnered with Harvard to digitize 360 years of U.S. case law, and then led LexisNexis's Practical Guidance division before taking the helm at LegalOn in 2022. Under his leadership, LegalOn's US and UK business quadrupled, secured a $50M Series E led by Goldman Sachs, and struck a strategic partnership with OpenAI - all while building attorney-curated AI playbooks that help legal teams cut contract review time by up to 85%.
John Haddock is the Chief Business Officer at Harvey, the $5 billion AI platform purpose-built for the legal industry. He joined in May 2025 after a decade at Stripe, where he scaled enterprise sales and led the Banking-as-a-Service division. A Stanford JD/MBA with roots in Big Law and a courtroom clerkship, Haddock now oversees a 50-person team of former Big Law lawyers helping the world's top firms embed AI into their daily workflows — from contract review to litigation briefs.
