ChangeSignal

ChangeSignal is the viral, no-guesswork tool that is rewriting the rules on how sales teams, founders, and growth pros hunt down buying intent. Forget cold calling into the dark. ChangeSignal reads the public signals that companies cannot hide: who they are hiring. The premise is brutally simple and incredibly effective. When a company suddenly posts a flood of sales roles, they are scaling their go-to-market team and need tools to support it. When they list machine learning platform engineers, they are making a massive AI investment. When they need partner managers, they are building a channel strategy. ChangeSignal automatically collects these job postings from major applicant tracking systems like Greenhouse, Lever, and Ashby. It then analyzes the patterns to detect meaningful shifts in strategy. For every change, it classifies the signal into specific buying-intent categories like Sales Expansion or AI Investment. Each signal comes with a ready-to-send outreach angle and a direct link to the source posting for verification. The product is built for founders, SDRs, AEs, and entire growth teams who live and die by outbound. You can browse every signal for free and subscribe for alerts via email, Slack, or Discord. For the real power move, the Pro plan at $29 per month unlocks the full intent and outreach layer on every company, giving you the exact words to start a conversation that actually matters. But ChangeSignal is not just about hiring. It has evolved. The platform now also tracks verified local buying-intent, specifically for San Francisco restaurants. By cross-checking two independent public filings (a new business registration and a California ABC liquor license at the same address), ChangeSignal surfaces real venues opening in SF months before any directory lists them. With 83 corroborated openings and nearly 2,000 live signals, it is the ultimate early warning system for anyone selling to new businesses. This is not a scraped list. This is verified, high-confidence evidence that a business is about to spend money.

Intent-Based Hiring Signal Detection

ChangeSignal does not just scrape job boards; it analyzes them for strategic intent. The tool automatically monitors job postings from major ATS platforms like Greenhouse, Lever, and Ashby. It detects meaningful changes in hiring patterns, such as a sudden burst of sales roles or a wave of engineering requisitions. Every detected change is then classified into specific buying-intent categories like Sales Expansion, AI Investment, or Customer Operations. This classification is not just a label; it includes a detailed explanation of the likely business need and a ready-to-send outreach angle, backed by a direct link to the source posting for complete verification.

Corroborated Local Business Openings

This feature is a game-changer for local sales. ChangeSignal cross-checks two independent public filings: a new business registration and a California ABC liquor license at the same address. This corroboration process confirms a real venue is opening in San Francisco, often months before it appears on any directory. Every lead ships with the exact address, the filing dates, and direct links to both source records as irrefutable evidence. This eliminates false leads and provides a verified, high-confidence signal that a business is about to invest in POS systems, payments, insurance, and marketing.

Real-Time Multi-Channel Alerts

Never miss a critical buying signal again. ChangeSignal allows users to subscribe to receive alerts instantly via their preferred communication channels. Whether you prefer email, Slack, or Discord, the tool pushes notifications the moment a high-intent signal is detected. This ensures that sales teams are the first to know when a company starts hiring for roles that indicate a need for their product. The speed of these alerts provides a massive competitive advantage, allowing for immediate outreach before competitors even know the opportunity exists.

Signal Scoring and Evidence Links

Not all signals are created equal, and ChangeSignal knows it. Each detected signal is assigned a score out of 100, indicating the strength and reliability of the buying intent. This scoring system helps users prioritize their outreach efforts on the hottest leads. Every signal is also accompanied by direct evidence links to the source job posting or the corroborated public filings. This transparency builds trust and allows sales professionals to verify the data themselves, ensuring they are always working with accurate and actionable intelligence.

Prospecting for B2B SaaS Sales Teams

For B2B SaaS companies, hiring is the ultimate leading indicator. A sales team can use ChangeSignal to find companies that are posting multiple sales development representative (SDR) or account executive (AE) roles. This is a clear signal that the company is scaling its go-to-market engine and will soon need sales engagement platforms, CRM tools, and data enrichment services. The ready-to-send outreach angles provided by ChangeSignal allow SDRs to craft hyper-personalized emails that reference the specific hiring change, dramatically increasing response rates and booking more meetings.

Targeting Companies with AI and Tech Investments

When a company posts roles like Machine Learning Engineer, AI Platform Architect, or Data Scientist, it is a massive red flag for investment. ChangeSignal classifies these as AI Investment signals. Vendors selling cloud infrastructure, GPU compute, data storage, or AI development tools can use this feature to identify potential customers who are actively building out their AI capabilities. The detailed explanation of the likely need helps sales reps position their product as the perfect solution for the company's immediate technical requirements.

Local Business Sales for Restaurants and Retail

This is where ChangeSignal shines for local vendors. A company selling POS systems, business insurance, payroll software, or local marketing services can use the SF Restaurant openings feature. When a new venue like "Song Wat" or "Kiku Sushi" is detected via corroborated public filings, the sales rep knows exactly where to go and what to sell. The suggested outreach angle tells them to pre-sell before the directory lists the business. This gives them a massive first-mover advantage over competitors who are still waiting for the business to appear on Yelp.

Strategic Account Research for Founders

Founders need to know where the market is going. By monitoring hiring signals across their target industry, founders can identify emerging trends and potential strategic partners or acquisition targets. For example, seeing a competitor hiring heavily for partner manager roles signals a new channel strategy. ChangeSignal provides the raw data and the analysis, allowing founders to make smarter decisions about product development, partnerships, and competitive positioning without having to manually scrape job boards or public records.

How does ChangeSignal determine buying intent from job postings?

ChangeSignal uses an automated analysis engine that monitors job postings from major applicant tracking systems like Greenhouse, Lever, and Ashby. It looks for meaningful changes in hiring patterns, such as a sudden increase in specific role types. It then classifies these changes into categories like Sales Expansion, AI Investment, or Customer Operations. This classification is based on the logical business need that typically follows such hiring patterns. For example, hiring sales reps usually indicates a need for sales tools, while hiring AI engineers indicates a need for AI infrastructure.

Is the data on ChangeSignal verified and reliable?

Yes, the data is highly reliable. For the hiring signals, ChangeSignal provides a direct link to the source job posting, allowing users to verify the information themselves. For the local restaurant openings in San Francisco, the verification process is even more rigorous. ChangeSignal cross-checks two independent public filings: a new business registration and a California ABC liquor license at the same address. Only when both records match and resolve to the same business is a signal generated. This corroboration process ensures that the leads are real and accurate.

Can I use ChangeSignal for free, and what are the limitations?

Yes, you can browse every signal on ChangeSignal for free. This includes viewing the list of companies hiring and the detected changes. You can also subscribe to receive alerts via email, Slack, or Discord to stay updated on new signals. The free tier is excellent for getting a feel for the data. The main limitation is that the full intent and outreach layer on every company is locked behind the Pro plan. This means the detailed explanation of the likely need and the ready-to-send outreach angle are only available to Pro subscribers.

What is the difference between the hiring signals and the restaurant signals?

The hiring signals focus on B2B buying intent, monitoring job postings from companies to predict their software and service needs. This is ideal for SaaS sales, tech vendors, and growth teams. The restaurant signals are a specialized local business feature currently focused on San Francisco. They use public business and liquor license filings to identify new restaurant openings before they are publicly listed. This is perfect for local vendors selling POS systems, insurance, payroll, and marketing services. Both are powered by the same core philosophy of using public data to predict buying intent.

ChangeSignal offers a free tier that allows users to browse all signals and subscribe to alerts via email, Slack, or Discord. For deeper insights, the Pro plan is available at $29 per month. This unlocks the full intent and outreach layer on every company, providing the exact words needed to start a conversation that matters.
