Building AI for Lawyers - Jacob Lauritzen, CTO of Legora

Jacob Lauritzen, CTO of Legora, discusses building AI agents for lawyers after the company's $550M Series E at an $8.8B valuation, covering how its evals team simulates customer work with three engineers and three lawyers because client data is confidential, and how Legora runs everything on Azure for law-firm approval. He says models already handle about 60% of legal work well, that complex analysis and editing across million-token contracts still need more intelligence, and that Legora has begun post-training open-weight models for narrow tasks like legal research. The company passed $100 million in ARR in April, less than 18 months after launch, and now has more than 1,800 customers.
