ChangeSignal is a buying-intent intelligence platform that detects real business investments by cross-referencing multiple independent public records — hiring changes, business registrations, liquor licenses, SEC filings, and DNS records — then surfaces verified signals and ready-to-send outreach angles for B2B sales and marketing teams.
What is ChangeSignal?
ChangeSignal monitors public data sources — including Greenhouse, Lever, Ashby job boards, SEC EDGAR, SF business registry, California ABC liquor licenses, certificate transparency logs, and web page diffs — to identify when a company is actively investing in a new initiative. It cross-checks two or more independent filings at the same address or company to confirm real activity, then outputs a dated signal (e.g., “Anju is opening a new location at 206 Valencia St”) with a confidence score, buying-intent categories, and a suggested outreach angle. The product is built by ChangeSignal and offers both a free browse-and-alert tier and a paid Pro tier.
Key Features
- Corroborated signals — Each signal is backed by two separate government records (e.g., a new business registration plus a liquor license at the same address) resolved to one entity, even when names differ or contain typos. Links to both source records are included as evidence.
- Real-time detection — Dates are captured as filings post; listings show “Detected” timestamps (e.g., Jul 10, 2026). Alerts can be delivered via email, Slack, or Discord webhook.
- Buying-intent classification — Every signal includes a list of likely product needs (e.g., POS & payments, business insurance, payroll, equipment financing, local marketing) based on the type of investment detected.
- Outreach angles — Each signal ships with a pre-written, ready-to-send outreach angle that names the specific change and the earliest possible window to sell.
- Multi-signal coverage — Beyond restaurant openings, ChangeSignal covers hiring, funding (SEC Form D), expansion (new subdomains, product launches), tech adoption (DNS switches, job-description tooling), and composite signals (e.g., funding plus hiring burst).
- Free browsing — All live signals are publicly browsable without login. Filters and webhook integration are available at no cost.
Who is it for?
- Founders and SDRs — Use verified restaurant-opening signals to prospect POS systems, payments, insurance, and payroll services to newly formed businesses before any directory lists them.
- AEs and growth teams — Monitor hiring bursts (sales, AI, customer ops) to identify companies scaling their revenue org, then reach out with relevant tooling (CRM, lead data, analytics).
- Sales ops and RevOps managers — Filter signals by buying-intent category (e.g., “growth investment” or “AI investment”) to generate a prioritized list of accounts in-market for specific product categories.
What can you do with ChangeSignal?
- Find restaurant openings months early: Cross-check SF business registry and ABC liquor licenses to surface venues like “Anju” at 206 Valencia St with a confidence score of 97/100. Pre-sell POS, insurance, and marketing before any directory lists them.
- Identify companies hiring for AI/ML roles: Detect when a company posts three new “ML engineer” positions, then reach out with a vector-DB or eval-tooling pitch. Each hiring signal links to the live job posts as evidence.
- Track expansion into new regions: Monitor certificate transparency logs for new subdomains (e.g., “europe.company.com”) combined with regional job postings to spot geographic scaling and offer local compliance or infrastructure services.
