What ChangeSignal is
ChangeSignal is a web service for sales and prospecting teams that turns changes in public data into evidence-linked buying signals. Its feeds cover hiring, funding, expansion, technology adoption, and other company and local developments. Hiring records track roles opened, closed, or reposted on public job boards; funding signals draw on SEC Form D filings and press wires. Expansion signals can reflect new regional subdomains, product launches, pricing changes, customer logos, and partner additions. The service also lists advertising, leadership, government contracts, app activity, incidents, new businesses, permits and licenses, local changes, and layoffs. Composite signals combine independent sources that align for a company within a short period, while company changes appear as dated records linked to evidence. One local example is San Francisco restaurant openings: ChangeSignal matches business registrations with California ABC liquor licenses by street address, even when names differ or have typos. Email alerts are available for these openings, with Slack or Discord webhooks for team visibility. The service is web-based and has a free plan.
