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.
