What is a signal, and why does it matter?
A signal is any observable event that suggests a prospect might be in-market, experiencing pain, or open to a conversation right now. Not eventually. Now.
The difference between a cold call that lands and one that doesn't is usually whether the rep had a reason to call — something specific, timely, and relevant to that prospect's world. Signals are that reason.
Without signals, outreach defaults to: "We help companies like yours with X." Which is what every other rep is also sending. With signals, it becomes: "I saw you just opened an office in Manchester — that usually means you're scaling headcount fast. Is the research side of outbound keeping up?"
Same product. Different conversation.
The 7 signal types that drive the most responses
Funding rounds
A company raising money is a company about to spend it. Series A and B are the sweet spots — enough runway to buy, enough pressure to act fast. Series C+ means they're scaling, which usually means headcount and tooling decisions being made centrally.
Hiring activity
Job postings are public strategy documents. A company hiring 10 SDRs is about to need your sales tech stack. A company hiring a "Head of Revenue Operations" is about to rethink their processes. A company posting for roles in a new market is about to expand there.
Executive changes
New leaders buy new things. A new VP of Sales in month one is evaluating every tool their team uses. A new CFO means budget reviews. New CMO means agency and tech stack audits. The window is roughly 90 days from start date — after that, they've inherited the status quo.
Product launches and expansions
A new product launch means new go-to-market motion, new personas, new outbound lists. A new market expansion means they need local tools, local knowledge, or local support. These events create immediate work — and immediate openings.
Tech stack signals
What tools a company uses tells you what they value, what gaps they have, and what they're likely to buy next. A company using Salesforce but no outreach tool is a gap. A company on HubSpot Starter who just crossed 50 employees is about to upgrade. Technographic data is the map.
Growth indicators
Headcount growth on LinkedIn, Glassdoor reviews mentioning rapid growth, office expansions announced publicly — these all point to a company that's scaling and likely buying. Headcount growth above 20% YoY is a strong indicator of budget availability.
News and intent signals
A company in the news — positive or negative — has something going on. Positive: they're growing, winning awards, or launching. Negative: they've had a public incident, regulatory scrutiny, or leadership controversy. Both create openings if your solution is relevant.

The honest truth: free sources cover 70–80% of the signals you need. Paid tools help you move faster and go deeper, but they don't replace the judgment call about whether a signal is actually relevant to your pitch.
Building a repeatable workflow
The goal is not to spend an hour researching each prospect. The goal is to spend 5 minutes and find the one signal that makes your outreach specific. Here's how to structure that:
-
Set up passive signal capture
Create Google Alerts for each target company name + key triggers ("funding", "hiring", "acquired"). Check LinkedIn company pages 1x/week. This surfaces signals without active searching.
-
Run active signal checks before outreach
Before any first touch, spend 3–5 minutes checking: LinkedIn activity (last 30 days), company news, job postings, and homepage. You're looking for one specific, timely hook — not a comprehensive report.
-
Map signals to your ICP triggers
Not all signals are relevant to every product. Map which signal types are meaningful for your specific solution. If you sell CRM software, hiring SDRs is a strong signal. If you sell logistics software, new warehouse locations are stronger. Build a signal → relevance map for your team.
-
Translate signals into hooks
A signal alone is not a hook. "I saw you raised a Series B" is not a hook — it's just acknowledgement. The hook is the implication: "...which usually means you're scaling the outbound team fast. Is your reps' research keeping pace?" Signal + relevant implication + question = hook.
-
Log and share what's working
The best signal → hook combinations get results. Build a team swipe file of which signal types are producing responses for your product and ICP. Review it monthly and prune what isn't working.
How to train reps to use signals
The hardest part is not finding signals — it's training reps to use them properly. Most reps, when told to "personalise", add the company name to the subject line and consider it done. That's not personalisation. That's mail merge.
The three personalisation tests
- Could this have been sent to 100 people? If yes, it's not personalised enough.
- Is the signal timely? A funding round from 18 months ago is not a hook. Last month is. Last week is better.
- Does the signal connect to your pitch? "I saw you just launched a new product" is noise unless your product helps them go to market for new products.
Signal review in team calls
Build signal review into pipeline meetings. Ask reps: "What signal made you reach out to this prospect?" If they can't answer, the outreach was based on fit alone — which is fine, but it sets expectations. A signal-driven outreach should convert at a meaningfully higher rate. Track it.
A simple calibration exercise
Take 10 recent prospects. Have each rep find one signal per prospect in under 5 minutes. Then compare what they found. You'll quickly identify who knows where to look and who's defaulting to "they're on our ICP list." That gap is trainable.
The prep principle: You don't need to know everything about a prospect. You need to know one specific thing that makes your outreach feel like it was written for them, not for your quota. One good signal beats five minutes of generic context.
Common mistakes
Using signals as filler instead of substance
Mentioning a signal in the subject line to get opens, then writing a generic pitch in the body. The prospect opened because of the signal. If the email doesn't deliver on the implication, they'll feel tricked. Signal → relevance → question, all the way through.
Researching too deep before first contact
Spending 30 minutes on a prospect who has a 10% chance of responding is a bad trade. Do enough research to find one strong signal, then reach out. If they respond, go deeper before the next touch.
Using the same signal for every prospect at a company
If you're targeting five people at the same company, don't send all five the same "I saw you just raised a round" hook. Use the company-level signal for one touchpoint, then differentiate by individual — their specific role, their LinkedIn activity, their tenure.
Ignoring negative signals
Layoffs, leadership departures, missed earnings, and public complaints are signals too — they tell you not to prioritise this account right now, or they point to a different type of conversation entirely. Not every signal is a green light.
