What ChangeSignal is
ChangeSignal is a web service that turns changes in public data into evidence-linked buying signals for sales and prospecting. Its listed sources include job postings, SEC filings, DNS records, ad libraries, status pages, and government contracts. Feeds cover hiring, funding, expansion, technology adoption, and other company or local changes. Hiring signals track roles opened, closed, or reposted on public job boards; funding signals include SEC Form D filings and press wires. Expansion signals can reflect new regional subdomains, product launches, pricing changes, customer logos, and partner additions identified through certificate logs and webpage differences. Composite signals bring together multiple independent sources that align for a company within a short period. Company changes appear as dated records linked to evidence. For San Francisco restaurants, ChangeSignal matches new business registrations to California ABC liquor licenses at the same street address, even when names differ or contain typos. The restaurant feed offers email alerts for detected openings, and Slack or Discord webhooks can provide team visibility. The restaurant alert signup is free, with an unsubscribe option. Those alerts are aimed at teams seeking to reach new venues early, including providers of POS, payments, insurance, supply, payroll, and equipment financing.
