Companies listed as a Clay integration

Source: Analysis of Linkedin bios of 140 companies that use Clay Integrations

I noticed that Clay Integrations users are overwhelmingly companies that help other businesses find, contact, and convert customers. These aren't traditional SaaS tools. They're data intelligence platforms, contact enrichment services, sales engagement tools, and GTM enablement companies. They build products that answer questions like "Who should I sell to?" and "How do I reach them?" Companies like Apollo.io, ZoomInfo, and People Data Labs provide contact databases. Others like Autobound and Twain generate personalized outreach. Many, like BetterContact and FullEnrich, aggregate data from multiple sources to improve accuracy.

These companies span the full spectrum, but there's a clear center of gravity around growth stage. I counted numerous Series A through Series C companies with 50-200 employees, like Champify, Ocean.io, and Crossbeam. There are also bootstrapped profitable companies like Close and lemlist, plus a handful of giants like Salesforce and HubSpot. The early-stage companies (seed funded, 2-10 employees) still talk like established players, suggesting the market itself is maturing even as new entrants arrive.
