Overview

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.
