Autumn builds research agents that answer questions about people and companies at scale. These AI agents are powered by a live index of over 1 billion people, 100 million companies, and state-of-the-art web research tools. Autumn is already in production with enterprise teams at Brex, Rippling, PostHog across sourcing, enrichment, and identity-verification workflows. We are a small, highly-technical team.
Our vision is to be the search engine that agents use when they need to understand people, their networks, and professional lives. The company was founded by Vishnu Sampathkumar; Shiv Kampani. It is part of YC Winter 2026. It is based in San Francisco, CA, USA.
