Yellow builds commercial intelligence for the global events industry.

Yellow Signal (yellowsignal.ai) turns the records organizers already own - registration, membership, community - into complete, verified, revenue-ready intelligence: resolved identities, enriched fields with source and confidence on every one, ranked segments, sponsor whitespace, and named prospect accounts. In 24 hours, not a quarter.

We also power event intelligence for field marketing teams, helping them find the few people who matter at every event and prove revenue impact (helloyellow.ai).

2x Event Technology Awards AI Edition 2026 winner: Best AI Start-Up in Events and Best AI for Audience Insights & Analytics.

Backed by Andreessen Horowitz. Built by ex-Google AI product leadership.
