Autobound is the signal layer for enterprise GTM. The company delivers 644 real-time business signals from 28 sources — including SEC filings, hiring velocity, podcast appearances, funding rounds, executive moves, earnings calls, and patent filings — through a single API. Data platforms like RocketReach, 6sense, and TechTarget license Autobound's signal infrastructure via OEM, embedding it into their own products. GTM teams use the Signal API to replace multiple data vendors with one integration. The platform covers 250M+ contacts and 50M+ companies with sub-200ms response times. Delivery options include REST API, webhooks, and scheduled file push. 85%+ of revenue comes from data licensing and OEM partnerships with enterprise data platforms.
