Meet The Startup Building AI For The Messiest Part of Law

Is owning the data still the moat in Legal AI? Sean Fitzpatrick, CEO of LexisNexis Legal

Is owning the data still the moat in legal AI?I spoke to Sean Fitzpatrick, a senior leader at LexisNexis - one of the largest legal AI companies in the world.Sean Fitzpatrick is CEO of the Global Legal Business at LexisNexis. He has been there for 21 years, growing up through the shifts from digital to cloud to AI, after starting out as a consultant at McKinsey.We discussed:→ Whether 200 billion proprietary documents are still a defining asset - or whether the nature of the moat has changed.→ Why "probably right" is the standard for frontier models, and why that standard fails in law.→ How their partnership with Harvey actually works.→ Sean's thoughts on hallucinations in legal AI.→ What happens to the junior lawyer apprenticeship model when the grunt work that builds judgment disappears.Sean has watched every major technology shift in legal over two decades, and makes the case for why content plus technology is far harder to displace than either alone. It was an honour to speak to Sean, and I hope you take something useful away from this. Know someone, or want to feature on the Best Practise Podcast?

Meet The Startup Building AI For The Messiest Part of Law

“Crack the chronology, crack the case.” That’s what Gregory Mostyn‘s [https://www.linkedin.com/in/gregory-mostyn-9b3a89b8/] father - a barrister, then judge for 42 years - was told on his first day in chambers. Decades later, it’s the founding insight behind Wexler. I spoke with Gregory Mostyn, co-founder and CEO of Wexler, the fact intelligence platform now used by huge massive circle firms in their litigation teams. Greg isn’t a lawyer. He grew up watching his father - who handled some of the highest-profile family cases in England - come home with ten ring binders to read before court the next morning. That image, plus a stint at Entrepreneur First, became Wexler. The company has 20x’d ARR since pre-seed and just raised $5.3m led by Pear VC. We discussed: → Why Wexler went deep on litigation when every other legal AI startup was going broad → The “verification tax” and where fully agentic legal AI actually breaks down → Why consumption pricing beats per-seat for litigation work (and how they structure it) → How his 67-year-old father is now vibe-coding apps for his tennis club → What it takes to close a Big Law deal in a week I absolutely loved recording this episode and I hope you enjoy listening to it just as much as I did.

Meet the Startup Building the Matter Management Layer Legal AI Forgot About

I keep hearing about legal AI tools that do the work better. What I haven’t heard, until now, is anyone building the tool that remembers what the work is actually for. In this episode I chat with Dillon Hirandiran, founder and CEO of Counsel (gc.inc) Dillon previously worked in investment banking, then built his first startup during Covid. The experience of navigating legal work as a founder - seed rounds, Delaware flips, cap tables - is what first drew him to the problem Counsel is now solving. Counsel is an autonomous matter management system for law firms - reading every email, every message, and maintaining a persistent context layer across everything a firm has going on. We discussed: → Why the hardest problem in legal AI has never really been document generation, but instead it’s CONTEXT retention across matters. → Why clients can’t always evaluate the quality of legal work, only its responsiveness → What a “10x attorney” actually looks like when AI handles the document layer, and why being a workhorse is the worst thing a junior lawyer can be right now → Why the biggest risk to Big Law isn’t pricing pressure from in-house or AI, but is actually their own talent leaving.

How this ex Amazon and Replit lawyer built the Legal AI platform she always wanted.

Cecilia Ziniti’s started as a paralegal at Yahoo in the early 2000s, when Yahoo was competing with Google and the internet was still being shaped by questions about content moderation, trust and safety, and what it meant to serve millions of users. She went to law school, then joined Morrison & Foerster, where she represented big brands like Apple. At Amazon, she was the founding lawyer on Alexa - she remembers getting excited about the first user review for a product that would eventually ship billions of devices. She eventually became general counsel at Replit, the developer platform used by millions of programmers. It was at Replit, in early 2022, that things changed. Cecilia had access to a pre-ChatGPT version of GPT through a deal she herself had negotiated between Replit and OpenAI. She tried it on a legal question. The result gave her chills. Her boss at the time, Replit CEO Amjad Masad, eventually noticed her attention had shifted. He asked whether her head was still in it. It was not. She left Replit and founded GC AI a week later, alongside co-founder and CTO Bardia Pourvakil, a fellow Replit alumnus. The company has since raised $73 million in total funding, including a $60 million Series B led by Scale Venture Partners and Northzone. It now powers over 1,400 companies, from Zscaler to Liquid Death. Cecilia was recently named to Inc.’s 2026 Female Founders 500 list.
