ChangeSignal

ChangeSignal is a specialized intent data platform engineered to transform how sales teams, founders, and growth professionals identify and act on buying intent. Unlike traditional intent data providers that rely on opaque behavioral signals or third-party cookie data, ChangeSignal leverages two distinct and publicly verifiable data sources to surface high-confidence sales opportunities. The primary mechanism monitors job postings from major applicant tracking systems including Greenhouse, Lever, and Ashby. By analyzing the specific roles a company is hiring for, ChangeSignal reveals where that organization is planning to invest its resources. For example, a surge in sales requisitions indicates go-to-market scaling, while machine learning platform roles signal AI infrastructure investment. The secondary mechanism, specifically for San Francisco restaurants, cross-checks new business registrations against California ABC liquor license filings at the same address to identify venues opening months before they appear on any directory. Each detected signal is classified into specific buying-intent categories with detailed explanations of the likely need and a ready-to-send outreach angle. Every signal includes direct links to source documents for verification. The product serves a broad audience including founders, SDRs, AEs, and entire growth teams. Users can browse all signals for free and subscribe to alerts via email, Slack, or Discord. The Pro plan at $29 per month unlocks the full intent and outreach layer on every company, providing exact conversation starters.

Job Posting Intent Analysis

ChangeSignal continuously monitors and ingests job postings from major applicant tracking systems including Greenhouse, Lever, and Ashby. The system analyzes posting volumes, role types, and departmental distribution to detect meaningful changes in a company's hiring patterns. For each detected change, the platform classifies the signal into specific buying-intent categories such as Sales Expansion, AI Investment, or Customer Operations. Each classification includes a detailed explanation of the likely underlying business need and a ready-to-send outreach angle, along with a direct link to the source job posting for independent verification.

Corroborated Public Filing Cross-Reference

For the San Francisco restaurant vertical, ChangeSignal employs a dual-source verification methodology. The system cross-references two independent public filings: a new business registration with the city and a California ABC liquor license application at the same physical address. This corroboration process ensures that every restaurant lead represents a real venue opening, not a scraped listing or speculative data point. Each lead ships with the exact address, filing dates, and direct links to both source records as evidence, providing sales teams with actionable leads months before traditional directories capture them.

Real-Time Signal Classification and Scoring

Each detected signal receives an automated confidence score from 0 to 100, indicating the strength and reliability of the buying-intent signal. The scoring algorithm considers factors such as the number of corroborating sources, the recency of filings or postings, and the specificity of the role or license type. Signals with scores above 90 are flagged as high-confidence opportunities. The system also automatically tags each signal with relevant buying-intent categories such as POS and payments, business insurance, payroll and scheduling, equipment financing, and local marketing and SEO.

Multi-Channel Alert Delivery

ChangeSignal supports real-time notification delivery across three communication channels: email, Slack, and Discord. Users can configure custom alert filters based on signal type, geographic location, company size, or buying-intent category. The alert system pushes new signals as they are detected, ensuring sales teams can act on opportunities within hours of the public filing or job posting. Each alert includes the signal summary, confidence score, suggested outreach angle, and direct links to source evidence for immediate verification and action.

Outbound Sales Prospecting for SaaS Companies

Sales development representatives and account executives can use ChangeSignal to identify companies actively building teams in specific functional areas. For example, a company posting multiple sales development roles signals an imminent need for sales engagement platforms, CRM tools, and lead generation software. The platform provides ready-to-use outreach angles based on the specific roles being hired, allowing SDRs to initiate conversations with relevant context and higher conversion rates. The direct links to job postings enable reps to verify the signal and tailor their messaging to the specific team being built.

Founder-Led Sales and Business Development

Startup founders and early-stage CEOs can leverage ChangeSignal to identify strategic partners and potential customers based on hiring signals. A company hiring partner manager roles indicates they are building out a channel strategy, presenting an immediate opportunity for partnership discussions. Similarly, companies investing in machine learning platform engineers represent potential customers for AI infrastructure, data labeling, or model deployment tools. The platform's detailed intent classifications help founders prioritize outreach to companies with the highest alignment to their product offering.

Local Business Sales for San Francisco Restaurants

Sales teams targeting the San Francisco restaurant market can use the corroborated openings feed to identify venues that are confirmed to be opening but not yet listed on any directory. This provides a critical time advantage for selling POS systems, payment processing, business insurance, payroll and scheduling software, equipment financing, and local marketing or SEO services. Each lead includes the exact address and filing dates, enabling sales teams to contact decision-makers during the pre-opening phase when purchasing decisions are being made.

Growth Team Market Intelligence

Growth and marketing teams can use ChangeSignal to monitor hiring trends across their target account list. By tracking which companies are expanding specific departments, growth teams can time their outbound campaigns to coincide with periods of organizational investment. The platform's signal classification enables automated lead scoring and routing, ensuring that high-intent signals are surfaced to the appropriate sales team members. The multi-channel alert system allows growth teams to set up automated workflows that trigger personalized outreach sequences based on specific signal types.

ChangeSignal offers a free tier that allows users to browse all detected signals and subscribe to basic alerts via email, Slack, or Discord. The Pro plan is available at $29 per month, which unlocks the full intent and outreach layer on every company. This includes detailed buying-intent classifications with explanations, suggested outreach angles, and the exact conversation starters needed to initiate high-relevance sales conversations. The Pro plan is designed for individual SDRs, AEs, founders, and growth team members who require deeper insights for their outbound sales efforts.

What data sources does ChangeSignal use to detect buying intent?

ChangeSignal uses two primary data sources. The first is job postings from major applicant tracking systems including Greenhouse, Lever, and Ashby. The platform monitors these systems for new postings and analyzes the specific roles, departments, and volumes to detect meaningful hiring pattern changes. The second data source, specifically for San Francisco restaurants, is public business registration filings and California ABC liquor license applications. The platform cross-references these two independent filings at the same physical address to confirm new venue openings.

How does ChangeSignal classify buying-intent signals?

Each detected signal is automatically classified into specific buying-intent categories based on the roles being hired or the type of filing detected. For job posting signals, categories include Sales Expansion, AI Investment, Customer Operations, and others based on the department and role types. For restaurant openings, categories include POS and payments, business insurance, payroll and scheduling, equipment financing, and local marketing and SEO. Each classification includes a detailed explanation of the likely business need and a suggested outreach angle for sales conversations.

Can I verify the signals myself?

Yes, every signal on ChangeSignal includes direct links to the source documents. For job posting signals, the platform provides a link to the original job posting on the company's applicant tracking system. For restaurant opening signals, the platform provides links to both the new business registration filing and the California ABC liquor license application. This transparency allows users to independently verify the accuracy and recency of every signal before taking action.

What notification channels does ChangeSignal support?

ChangeSignal supports real-time alerts via email, Slack, and Discord. Users can configure custom filters to receive notifications only for specific signal types, geographic locations, companies, or buying-intent categories. The alert system is designed to push new signals as they are detected, typically within hours of the public filing or job posting being made. Users can browse all signals for free without subscribing to alerts, and can upgrade to the Pro plan for deeper intent analysis and outreach assistance.
