ChangeSignal

ChangeSignal is an automated buying-intent detection platform that transforms how sales teams, founders, and growth professionals identify companies ready to purchase their products. Instead of relying on guesswork or outdated lead lists, ChangeSignal monitors clear, public signals to surface high-intent prospects before your competitors reach them. The core product analyzes job postings from major applicant tracking systems like Greenhouse, Lever, and Ashby. The logic is straightforward: the roles a company posts publicly reveal exactly where it plans to invest resources next. A sudden burst of sales job requisitions indicates a company is scaling its go-to-market team. Multiple machine learning platform roles signal a major artificial intelligence investment. New partner manager roles show a company is building out a channel strategy. ChangeSignal automatically collects these postings, detects meaningful changes in hiring patterns, and classifies each signal into specific buying-intent categories such as Sales Expansion, AI Investment, or Customer Operations. Every signal includes a detailed explanation of the likely need, a ready-to-send outreach angle, and a direct link to the source job posting for verification.

Beyond hiring signals, ChangeSignal has expanded into verified local buying-intent data. For San Francisco restaurants specifically, ChangeSignal cross-checks two independent public filings: a new business registration and a California ABC liquor license at the same address. This corroboration process surfaces real venues opening in the city months before they hit any directory. Each restaurant lead ships with the address, filing dates, and links to both source records as evidence. The platform currently tracks 83 corroborated openings and 1,939 live SF restaurant signals. Every signal comes with a signal strength score out of 100, detected date, likely buying intent categories, and a suggested outreach angle. Users can browse every signal for free and subscribe to receive alerts via email, Slack, or Discord. For deeper insights, the Pro plan at 29 dollars per month unlocks the full intent and outreach layer on every company. ChangeSignal serves founders, SDRs, AEs, and entire growth teams who rely on outbound sales to drive revenue. The platform streamlines the entire workflow from signal detection to outreach execution, eliminating manual research and guesswork.

Automated Job Posting Monitoring

ChangeSignal automatically collects job postings from major applicant tracking systems including Greenhouse, Lever, and Ashby. The platform continuously scans these sources to detect new postings and changes in hiring patterns. When a company posts multiple roles in a specific department or function, ChangeSignal flags this as a buying-intent signal. The automation eliminates the need for manual job board monitoring and ensures you never miss a critical hiring shift. Every detected change includes a direct link to the source posting for instant verification, so you can confirm the signal before taking action.

Buying Intent Classification with Outreach Angles

Every detected change receives automatic classification into specific buying-intent categories such as Sales Expansion, AI Investment, Customer Operations, or POS and payments. This classification is not just a label. Each signal comes with a detailed explanation of the likely business need driving the hiring activity. More importantly, ChangeSignal generates a ready-to-send outreach angle tailored to that specific signal. For example, a restaurant opening signal includes suggested outreach for POS systems, business insurance, payroll scheduling, equipment financing, and local marketing. This feature eliminates the time spent crafting personalized messages and ensures your outreach is relevant and timely.

Corroborated Local Business Openings

ChangeSignal has developed a unique verification system for local business intelligence, starting with San Francisco restaurants. The platform cross-checks two independent public filings: a new business registration and a California ABC liquor license at the same address. When both filings align within weeks of each other, ChangeSignal confirms a real venue opening months before any directory lists it. Each lead ships with the address, filing dates, and links to both source records as evidence. A signal strength score out of 100 indicates the confidence level of the corroboration. This feature provides verified, actionable leads that traditional scraping tools cannot match.

Multi-Channel Alert Subscriptions

Users can subscribe to receive alerts for new signals through multiple channels including email, Slack, and Discord. The alert system delivers real-time notifications when ChangeSignal detects a new buying-intent signal matching your criteria. You can filter alerts by signal type, company size, location, or specific intent categories. This multi-channel approach ensures you never miss a critical signal regardless of where you work. The free tier allows browsing all signals, while Pro subscribers receive enhanced alerts with full intent and outreach details. The alert system integrates directly into your existing workflow without requiring additional tools or platforms.

Outbound Sales Prospecting for SDRs and AEs

Sales development representatives and account executives can use ChangeSignal to identify companies actively building teams that need their products. When a company posts multiple sales roles, it signals an expanding go-to-market operation that likely needs CRM tools, sales engagement platforms, or training services. Similarly, machine learning engineering roles indicate AI infrastructure investments that require cloud services, data pipelines, or specialized hardware. Instead of cold calling random companies, SDRs and AEs can target organizations with verified hiring intent and use the provided outreach angles to start conversations that matter. This approach dramatically increases response rates and shortens sales cycles.

Founder-Led Sales for Early-Stage Startups

Founders of early-stage startups can leverage ChangeSignal to find their first customers without expensive sales teams or data subscriptions. The free browsing tier allows founders to manually review signals and identify companies that match their ideal customer profile. For example, a founder selling restaurant POS systems can monitor the San Francisco restaurant openings feed and contact venues before they even sign a lease. The suggested outreach angles provide ready-to-use messaging that resonates with the specific buying intent. This use case enables resource-constrained founders to generate pipeline without traditional outbound sales infrastructure.

Growth Team Pipeline Generation

Growth teams responsible for top-of-funnel activities can use ChangeSignal to automate lead generation across multiple verticals. The platform surfaces signals for different buying-intent categories simultaneously, allowing growth teams to run parallel outbound campaigns. For instance, a growth team can target companies hiring for sales expansion, AI investment, and customer operations all from the same dashboard. The classification system helps prioritize leads based on signal strength and relevance. Growth teams can set up Slack or Discord alerts to distribute leads instantly to the right reps, ensuring fast response times on time-sensitive opportunities.

Local Business Service Provider Targeting

Service providers targeting local businesses can use ChangeSignal's corroborated opening data to reach new venues before competitors. A POS provider can contact every new San Francisco restaurant opening before they select a payment system. A business insurance agent can pitch policies to restaurants that just filed their business registration. A local marketing agency can offer SEO services to venues that have not yet established an online presence. The verified filing dates give service providers a critical timing advantage. Each lead includes the exact address and links to source records, enabling immediate follow-up with accurate information that builds credibility.

ChangeSignal offers a free tier that allows users to browse every signal for no cost. The free tier includes access to all detected hiring intent signals and local business openings with basic signal details. For users who need deeper insights, the Pro plan is available at 29 dollars per month. The Pro plan unlocks the full intent and outreach layer on every company, providing detailed classification explanations, ready-to-send outreach angles, and enhanced alert configurations. Pro subscribers also receive priority access to new signal categories and features as they launch. There is no annual commitment required for the Pro plan, and users can upgrade or downgrade at any time.

What sources does ChangeSignal monitor for job posting signals?

ChangeSignal automatically collects job postings from major applicant tracking systems including Greenhouse, Lever, and Ashby. These platforms cover thousands of companies across all industries. The platform continuously scans these sources for new postings and changes in hiring patterns. For local business openings, ChangeSignal monitors new business registrations and California ABC liquor license filings from public government databases. The combination of these sources provides comprehensive coverage of buying-intent signals across both technology companies and local businesses.

How does the signal classification and outreach angle system work?

When ChangeSignal detects a meaningful change in hiring patterns, it automatically classifies the signal into specific buying-intent categories such as Sales Expansion, AI Investment, Customer Operations, or POS and payments. The classification is based on the roles being hired and the department those roles belong to. For each classification, ChangeSignal generates a detailed explanation of the likely business need driving the hiring activity. The system then creates a ready-to-send outreach angle that addresses that specific need. For example, a restaurant opening signal generates outreach angles for POS systems, business insurance, payroll scheduling, equipment financing, and local marketing. This automation eliminates the need to research and craft personalized messages for each prospect.

Can I use ChangeSignal for free and what does the free tier include?

Yes, you can browse every signal on ChangeSignal for free without any subscription. The free tier gives you access to browse all detected signals across hiring intent and local business openings. You can view signal details including the signal strength score, detected date, likely buying intent categories, and suggested outreach angles. The free tier also includes access to the evidence links for verification. For users who want deeper insights, the Pro plan at 29 dollars per month unlocks the full intent and outreach layer on every company, giving you the exact words to start a conversation that matters.

How does the corroboration process for restaurant openings work?

ChangeSignal cross-checks two independent public filings to confirm a new restaurant opening. The platform compares a new business registration filing with a California ABC liquor license application at the same address. When both filings appear within weeks of each other and resolve to the same business entity, ChangeSignal confirms the opening as a real venue. This corroboration process eliminates scraped listings and false positives. Each confirmed opening includes a signal strength score out of 100, the exact address, filing dates for both documents, and direct links to the source records. This verification process provides leads months before any directory or review site lists the venue.
