ChangeSignal

Alright, let's be real for a sec. You're tired of shooting arrows in the dark with your sales outreach, right? Cold emailing companies that have zero interest in what you're selling is basically digital spam, and you know it. Enter ChangeSignal, the tool that's basically a cheat code for finding companies that are literally screaming "we need your product." How? By stalking their job postings like a pro. Yeah, seriously. When a company suddenly posts five sales roles, they're scaling their go-to-market team and probably need CRM tools, sales enablement, or recruitment software. When they drop a machine learning engineer req, they're about to drop serious cash on AI infrastructure. ChangeSignal scrapes job boards from Greenhouse, Lever, and Ashby, then analyzes those postings to detect meaningful hiring shifts. Every signal comes with a buying intent category, a detailed explanation of what they probably need, and even a suggested outreach angle so you don't have to think. It's built for founders, SDRs, AEs, and growth teams who live and die by outbound. You can browse everything for free, subscribe to alerts via email, Slack, or Discord, and if you want the full sauce, the Pro plan unlocks the intent layer for every company. But wait, there's more. They also do this wild thing for San Francisco restaurants where they cross-check two independent public filings — a new business registration and a liquor license — to find venues opening months before anyone else. That's next-level intel for anyone selling POS systems, insurance, or marketing to restaurants. Basically, ChangeSignal turns public data into your personal sales crystal ball. No cap.

Hiring Signal Detection

This is the bread and butter. ChangeSignal automatically pulls job postings from major applicant tracking systems like Greenhouse, Lever, and Ashby. It doesn't just grab them though — it analyzes the patterns to detect real, meaningful changes. If a company that usually posts one engineering role a month suddenly drops five sales roles, that's a signal. The tool classifies these into specific buying-intent categories like Sales Expansion, AI Investment, or Customer Operations. Each signal comes with a detailed breakdown of what the company likely needs and a ready-to-send outreach angle. You also get a direct link to the source job posting so you can verify the intel yourself. It's like having a crystal ball, but legal.

Corroborated Restaurant Openings

This feature is straight fire for anyone selling to restaurants. ChangeSignal doesn't just scrape Yelp or Google Maps for "coming soon" listings. Instead, it cross-checks two independent public filings — a new business registration and a California ABC liquor license at the same address. If both line up, you know a real venue is opening. Each lead ships with the address, filing dates, and links to both source records as evidence. You get a signal score out of 100, and the data is updated in real-time. Right now there are 83 corroborated openings and 1,939 live SF restaurant signals. That's months of early access before any directory lists them.

Buying Intent Classification

This isn't just a dumb label. Every hiring signal gets classified into a specific buying-intent category that tells you exactly what the company is probably shopping for. For example, a sudden burst of sales job requisitions means "Sales Expansion" and suggests they need CRM, sales enablement, or recruitment tools. Multiple machine learning platform roles signal "AI Investment" and a need for AI infrastructure or data pipelines. Partner manager roles indicate "Channel Strategy" and a need for partner management software. The classification comes with a detailed explanation of the likely need and a suggested outreach angle that you can literally copy-paste. It's basically free consulting.

Multi-Channel Alerts

You don't have to sit on the website refreshing all day. ChangeSignal lets you subscribe to alerts via email, Slack, or Discord. That means you can be chilling at your desk, catch a notification that Company X just started hiring for three sales roles, and be the first person to reach out. The alerts are real-time and tied to the signals you care about. You can filter by signal type, company size, or industry so you only get notified about the opportunities that actually matter to your business. No noise, just the good stuff.

Outbound Sales Prospecting for SDRs and AEs

You're an SDR or AE grinding on outbound, and your manager is breathing down your neck for meetings. Stop guessing which companies to target. With ChangeSignal, you get a list of companies that are actively hiring in roles that indicate buying intent. If a company posts a "Head of Sales" role, they're scaling their team and probably need your sales tool. If they post a "Customer Success Manager," they're investing in retention and might need your CS platform. You can browse signals for free, get the outreach angle, and hit them up before your competitors even know they exist. It's like having a radar for revenue.

Founders and CEOs Identifying Early Adopters

You just launched a product and need to find your first 10 customers. Instead of cold emailing random startups, use ChangeSignal to find companies that are hiring for roles that match your product. If you sell a machine learning platform, look for companies posting ML engineer roles. If you sell a sales enablement tool, look for companies scaling their sales team. The Pro plan at $29 per month unlocks the full intent and outreach layer, giving you the exact words to start a conversation that matters. This is how you get your first paying customers without wasting time.

Restaurant Tech Vendors Targeting New Openings

You sell POS systems, business insurance, payroll software, equipment financing, or local marketing services. Your ideal customer is a restaurant that just opened or is about to open. ChangeSignal's SF restaurant feature gives you a list of corroborated openings with addresses, filing dates, and a signal score. You can reach out months before any directory lists them, when they're actively making purchasing decisions. The suggested outreach angle is literally provided for you. No more cold calling random restaurants hoping they're in the market. This is precision targeting.

Growth Teams Building Account Lists

You're on a growth team and need to build a list of high-intent accounts for an upcoming campaign. ChangeSignal lets you filter by signal type (Sales Expansion, AI Investment, Customer Operations, etc.) and export those companies. You can then layer in your own data or run them through your CRM. The alerts feature means you can set up a Slack channel where new signals get posted automatically, so your team is always in the loop. This turns your outbound from a spray-and-pray operation into a sniper rifle.

How does ChangeSignal know a company is hiring?

ChangeSignal automatically collects job postings from major applicant tracking systems like Greenhouse, Lever, and Ashby. These are the systems most tech companies use to manage their hiring. The tool doesn't just grab the job titles though — it analyzes the patterns over time to detect meaningful changes. For example, if a company that usually posts one role a month suddenly posts five, that's a signal. You can click through to the source job posting to verify everything yourself. It's all public data, just organized in a way that actually makes sense for sales.

What kind of buying intent can I detect?

The tool classifies signals into specific categories like Sales Expansion, AI Investment, Customer Operations, and Channel Strategy. Each category comes with a detailed explanation of what the company likely needs and a suggested outreach angle. For example, a "Sales Expansion" signal means the company is scaling its go-to-market team and probably needs CRM, sales enablement, or recruitment tools. An "AI Investment" signal means they're building out machine learning infrastructure and might need data pipelines, GPU compute, or ML platforms. The classification is based on the roles they're hiring for.

Is the San Francisco restaurant data accurate?

Yes, and that's the whole point. ChangeSignal doesn't scrape Yelp or Google Maps. Instead, it cross-checks two independent public filings — a new business registration and a California ABC liquor license at the same address. If both filings line up within weeks of each other, that's a strong signal that a real venue is opening. Each lead includes the address, filing dates, and links to both source records so you can verify the intel yourself. Right now there are 83 corroborated openings and 1,939 live signals in SF. It's the earliest possible window to pre-sell your product.

Can I get alerts in real time?

Absolutely. You can subscribe to receive alerts via email, Slack, or Discord. The alerts are triggered in real-time when a new signal is detected that matches your criteria. You can filter by signal type, company size, or industry so you only get notified about the opportunities that matter to your business. This means you can be the first person to reach out to a company that just started hiring for roles that indicate buying intent. First mover advantage is real, and this is how you get it.

You can browse every signal for free with no credit card required. If you want deeper insights, the Pro plan is $29 per month. This unlocks the full intent and outreach layer on every company, giving you the exact words to start a conversation that matters. The Pro plan also includes access to the detailed buying-intent classifications and suggested outreach angles for every signal. There's no enterprise tier mentioned, so for most sales teams and founders, the Pro plan is all you need.
