Tanguy Chau is the Co-Founder and CEO of Paxton AI, a Palo Alto-based legal tech company building an AI-powered assistant for lawyers.

Under his leadership, Paxton raised a $22M Series A in January 2025 (total $28M), achieved a 94% non-hallucination rate on the Stanford Legal Hallucination Benchmark, and grew 14x in monthly recurring revenue over nine months - serving clients from solo practitioners to the nation's 20 largest law firms.
O-Boy is the world's first satellite-connected emergency rescue smartwatch, built for adventurers and professionals who operate beyond cellular coverage. Designed by Belgian studio Futurewave for startup LifeLineSat, it lets you send GPS-pinpointed rescue signals, custom messages, or live location tracking directly via satellite - no phone required.
