Intent signals: readiness you can actually detect

An intent signal is an observable event suggesting a company may be entering a buying window: a hiring spree, a new director, a funding round, a change of premises. Most of what is sold as "intent data" is inferred from browsing behaviour you cannot verify; the signals worth building into a list are the public ones you can check yourself. For a UK B2B service firm, detectable beats sophisticated every time.

What actually counts as an intent signal?

Separate two things that get conflated: fit and readiness. Fit is whether a company matches your ideal client profile — the right sub-vertical, headcount, geography. Readiness is whether something is happening inside that company right now that makes your offer timely. Fit is the foundation of any list, and building it properly is covered in the B2B database building guide. Intent signals sit on top: they do not replace fit, they sequence it. A perfectly matched company with no signal is still worth contacting; a signalling company outside your ICP is not.

A useful signal has three properties. It is observable — you can point at the evidence. It is recent — signals age quickly, and like all prospect data they decay month by month. And it is plausibly connected to the problem you solve. A firm hiring its first salesperson is a strong signal for someone selling pipeline systems; it is a weak signal for someone selling office fit-outs.

Which signals can you detect without an enterprise budget?

The signals available to a 5–50-staff firm are mostly free and public:

• Hiring activity. Job postings are the single richest source. A firm advertising for a role tells you what it is investing in, what it is struggling with, and roughly what it will spend.
• Leadership changes. A new managing director or commercial director typically reviews suppliers and systems in their first months. Companies House filings and LinkedIn announcements surface these reliably.
• Filings and registrations. Confirmation statements, new appointments and account filings on the public register signal growth, restructuring or new ownership.
• Funding and expansion. Announced raises, new offices, acquisitions — usually press-released, easy to monitor.
• Website and positioning changes. A relaunch or a new service line commonly precedes a push for growth.

None of this requires paid intent platforms. It requires a process for looking.

How do you build signals into the list process?

The mechanism is a priority queue layered onto a fit-based list. When you define your ICP, then choose two or three signals that plausibly correlate with buying your service — no more, or the checking becomes the job. When a company on your list shows one of those signals, then move it into a priority segment that gets sequenced first. When you write to that segment, then reference the signal once, plainly, in the first email — "you're hiring a second account manager" — and connect it to the problem you solve. When a signal is more than roughly ninety days old, then treat it as expired and return the company to the standard queue.

That is the whole system. The signal changes the order and the opening line; the rest of the campaign runs as normal.

Should you buy third-party intent data?

Mostly no, at this end of the market. Commercial intent platforms aggregate topic-level browsing behaviour — companies allegedly researching a category — and sell it at enterprise prices. The signal is inferred, the methodology is opaque, and you cannot audit a single record. For firms selling into the mid-market and smaller, the coverage is typically thin precisely where you need it. The budget is better spent on list accuracy: Companies House prospecting plus verification will beat an intent feed you cannot inspect.

How much should a signal change your outbound?

Less than the vendors suggest. A signal earns a company earlier contact and one specific sentence — that is all. The offer, the sequence and the follow-up discipline stay the same, because cold email works when the fundamentals work, not because of a clever trigger. And remember what a signal is evidence of: readiness, not identity. Knowing when to contact a company is worth little if you are contacting the wrong companies — which is why signal work pairs naturally with lookalike prospecting, where you establish who to target from the clients you have already won.

Signals are a sharpening stone, not the blade. Get the list right first; then let readiness set the order.
