Autumn AI is a real-time signal intelligence platform for go-to-market teams. Its core product is a Deep Research Agent that continuously monitors public sources, such as GitHub commits, blog posts, social media, job postings, SEC filings, and company announcements, to surface buying signals the moment they appear and to build detailed intelligence profiles on prospects at scale.

Rather than relying on static contact databases, Autumn aggregates live signals to identify accounts and people that match a team's ideal-customer criteria, then enriches each profile with context such as technical interests, recent company activity, hiring patterns, and expansion indicators. The goal is to compress the manual research a sales rep would otherwise do before reaching out, enabling more precise and timely outbound.

The platform is delivered through a dashboard for search, research, and list building, and exposes its data via an API, an MCP integration for tools like Claude and Cursor, and CSV export. It serves B2B GTM teams, sales development representatives, and account executives who need up-to-date prospect intelligence.

Autumn AI is a Y Combinator company (Winter 2026 batch) and counts Pioneer Fund among its backers. Pricing is not published; prospective customers book a demo. Note that a separately named company, Autumn (YC S25), builds billing infrastructure for AI startups and is unrelated to this sales intelligence product.
