Real-time GTM signal infrastructure that sources, verifies, and contextualizes business events. We detect funding rounds, acquisitions, hiring, executive job changes, and other signals from across the web in under a minute, with original source attribution and full company context.

Most B2B data products are databases. They tell you what a company looks like. We tell you what just happened to it. A funding round 60 seconds ago. A new VP of Sales hired this morning. A competitor acquired this week. Live, source-attributed signals you can act on while the buying window is open.

50k+ funding rounds. 18k+ M&A signals. 679k+ hiring signals. 960k+ executive job changes. 19k+ active investors. 189k+ active companies. All from real activity, all growing every minute.

B2B data vendors, GTM teams at companies like HubSpot, Plaid, and Convert, and platforms including Bytemine, Salesforge, Databar, CompanyEnrich, Signalist, Caide, and Master Inbox.
