Most B2B contact databases are recycled versions of the same LinkedIn-derived data. DataSigma is different — we index verified business contacts directly from the public web, surfacing decision-makers the incumbents don't have. The result: 101M+ contacts, 58% of which don't exist in Apollo and ~50% are not on LinkedIn. That includes 5.6M founders, owners, and managing directors — more than 2x what the largest platforms offer — because the people who actually sign checks are often the ones missing from scraped-profile databases. Every contact comes with a verified email and a source URL, so you can see exactly where the data came from. No black-box enrichment. No stale exports. Who it's for: sales teams, agencies, and data teams that have exhausted the usual databases and need net-new coverage — especially SMB owners, niche industries, and long-tail companies.
