B2B buying signals: why one signal is rarely enough

A B2B buying signal is an event that suggests a company might be ready to buy: a funding round, a new hire, a leadership change, an acquisition, a former customer turning up at a new company. On its own, one signal rarely tells you enough. Layered together, signals tell your reps who to contact, when, and what to say.

Signals are now a standard part of outbound, and most teams watch the same ones. Funding rounds and job changes show up in every tool, so everyone sees them at the same moment. What makes a signal useful is how it's chosen, what it's combined with, and when your rep acts on it.

Why does timing matter so much?

Most buyers have made up their mind before they talk to anyone. In 6sense's 2025 study of nearly 4,000 B2B buyers, the winning vendor was already on the buyer's day-one shortlist 95% of the time, and four out of five deals went to the vendor the buyer contacted first. Buyers also reached out earlier than the year before, at about 61% of the way through their journey, down from 69%.

Signals are how you get in front of a buyer while that shortlist is still forming, with a reason to reach out that fits what's happening at their company.

Why is one signal rarely enough?

One signal on its own is thin. A company raising money tells you they have budget. It doesn't tell you whether they have the problem you solve, or whether now is when they'll deal with it.

Layering is what gives a signal relevance. A funding round plus a job posting for a role your product supports. A leadership change at an account that has already been on a deal with you. Each extra signal narrows the list and gives your rep a more specific reason to get in touch.

Which signals give the highest return?

On a build for a Series A B2B SaaS team, two signals stood out above everything else.

The first was people who used to be customers and had moved to a new company. They already knew the product and had seen it work, and now they were somewhere that might need it. That was consistently a very good sign.

The second was people who had previously been involved in a deal. They already had context on the product and on the conversation.

The build also picked up signals that were specific to the client's sector. They didn't fire often, and plenty of accounts never matched them. But the ones that did hit were very high quality.

That's where I'd start any team: with the signals that give you the highest return, even if they fire less often.

Do you need a system, or signals built for your industry?

Both. A system gives you the baseline: the common signals, pulled together and delivered consistently so your reps can rely on them.

On top of that, most industries have signals that matter specifically to them, and those are often where the best leads come from. A standard setup won't find them, because they depend on what your product does and who buys it. You build them in on top of the system once you know what they are.

When does funding actually matter?

Funding is the signal everyone watches, and it only really matters in certain sectors, or for certain products. If your product is something companies buy after a raise, it's a strong signal. If it isn't, it's noise.

Funding also means something different at different stages. What a company does with a seed round is different from what it does with a later round, and your messaging needs to reflect that. The same congratulations note sent to every funded company treats very different situations as one.

And funding alone isn't a reason to buy. "You've raised, so spend some of it with us" gives the buyer nothing to respond to. Attach the raise to another symptom the money creates, like a hiring push or a new team being built. That second signal is what makes the outreach relevant.

The same goes for M&A. If acquisitions reliably create the problem your product solves, they're a great signal for you. If they don't, leave them out.

Why shouldn't you pitch a new leader straight away?

Leadership changes are a good signal with a timing trap. When a new leader starts, reps want to reach out immediately. If they're notified that day, they won't wait. They'll send the pitch that day.

A new leader in their first three months is drinking from a fire hose. They're learning the team, inheriting problems, and putting out fires. A pitch in that window is competing with everything else on their plate.

Build the timing into the system. Decide when the AE gets notified, rather than alerting them the moment the change happens, and use those first months to start nurturing the relationship instead of pitching.

Where should an early-stage team start?

Start small, with a few signals chosen for return rather than volume:

• Past relationships first. Former customers at new companies, and people who have been on a deal before.
• Public signals that fit your product. Check whether funding or M&A actually change anything for your buyers before you add them.
• Signals specific to your industry. They'll fire less often, and the hits will be worth more.
• Layers. Wherever you can, pair a signal with a second one before a rep acts on it.
• Timing. For signals like leadership changes, decide when the rep hears about it as well as whether they do.

Signals work when they give your reps a specific, timely reason to talk to someone. The GTM automation page shows how that fits into the wider research, scoring and prep layer that sits in front of your reps.
