Signal-based prospecting is the process of prioritizing accounts using observable events—such as funding, leadership changes, or hiring—and researching whether those events create a relevant reason to contact a specific buyer.
Instead of treating every company that matches a filter as equally timely, you ask: what changed, why might it matter, and who could be affected? The event is the start of the research, not the conclusion.
What counts as a buying signal?
A useful signal is specific, observable, and connected to a problem your product solves. Coolie’s Signals Best Practice Guide similarly recommends questions that can be checked against public sources. The examples below are illustrative, not reports of actual companies.
- Funding: a B2B software company announces a new round. It may have resources for expansion, but the announcement does not reveal what it will buy.
- Leadership change: a new VP of Sales joins. They may review the existing process, but there is no basis to assume they want to replace the current stack.
- Sales hiring: several SDR vacancies appear. Research may uncover a ramp-up or account-prioritization challenge.
- Technology change: a company publicly announces a migration. Verify its scope and date before connecting it to your offer.
How do you evaluate a signal?
- Check account fit. Does the company match your market, size, geography, and use case? Timing cannot rescue a poor-fit account.
- Check the evidence. Read the original announcement or job listing. Record what it says, its date, and what remains unknown.
- Form a role-specific hypothesis. Describe a possible problem created by the change. Mark it as a hypothesis until the buyer confirms it.
- Assess freshness and relevance. There is no universal expiry date. A role announcement from yesterday and a multi-quarter transformation need different timing.
- Decide whether outreach adds value. If your only connection is “congratulations,” more research—or no message—may be the better next step.
A worked example: hiring four SDRs
Imagine a workflow SaaS company posting four SDR openings. The observable fact is hiring activity. A plausible hypothesis is that its RevOps leader may need consistent account research as new reps ramp up. Budget, urgency, and dissatisfaction with current tools remain unknown.
Instead of claiming “you need our platform,” ask: “Saw the SDR openings. How are you planning to keep account research consistent as the team ramps?” It links the event to a question the recipient can answer, without pretending you know their priorities.

What are the limitations?
Public information can be stale, incomplete, or interpreted incorrectly. Multiple sellers may respond to the same event. Automated research can introduce errors, and a relevant message still might arrive at the wrong time. Human review is essential.
For US/EU outbound, check the applicable privacy, electronic marketing, and platform requirements before collecting data or contacting people. Public availability alone does not grant unlimited permission to use personal information. This guide is not legal advice.
Common questions
How is a signal different from intent?
A signal is an observation. Intent is an inference about willingness or readiness to buy, sometimes supported by direct behavior. Funding or hiring alone does not establish intent.
Can I use signals alongside a lead database?
Yes. A database can help identify accounts and contacts; signals can add context and prioritization. They can complement each other rather than require an either-or decision.
How do I measure whether this improves outbound?
Use a defined cohort and compare qualified conversations and opportunities with a consistent baseline. Track source freshness and account fit too. Avoid attributing every improvement to signals when targeting or messaging also changed.
