Third Chair(YC X25) is building AI Agents for in-house legal teams. The team comprises of 2 second-time founders with past exits. Yoav previously cofounded social media analytics startup Trendpop(YC W21) that scaled to 1M in ARR in 16 months building a platform that processed millions of social posts per day. Shourya previously cofounded a consumer finance startup Fello(YC W22) that scaled to over 2 million users and managed over 600k monthly active users and over $250,000 in monthly investments.

Third Chair is building vertical AI-native workflows for legal teams that help them complete end-to-end workflows that previously required 100s of hours. This is accomplished by building SOTA AI agents that browse the web, download and collect evidence, draft letters and more. We've grown 88% last month and went from 0 to 100k ARR in 5 months.
