A funding signal fires when a company announces it has raised capital. It tells you spending capacity now exists and that someone wrote a plan for that capacity during the raise. It does not tell you your category is in the plan, which is the distinction most funding-triggered outbound gets wrong.
What it actually predicts
Two things, reliably.
Capacity. Money that was not there is there now. For a seed or Series A company this often means the first real budget for anything beyond salaries.
A written plan. Nobody raises without a use-of-funds story. That story was argued over for weeks and it names the functions that will grow. If your product serves one of those functions, you are selling into a decision that has already been half made.
The second point is why the use-of-funds language in the announcement is worth more than the amount. "Expanding go to market" is a different prospect from "extending our runway", and both come with the same headline number.
What it does not predict
That anyone there wants your product. A round is money plus a plan, and your category is either in the plan or it is not.
It also does not predict availability. In the fortnight after an announcement the team is fielding press, recruiters, and every vendor whose news feed caught the same event you did. A funding signal is the single cheapest signal to acquire, which means it is the most crowded one to act on.
And it says nothing about who decides. A round frequently arrives before the person who would buy from you has been hired. Half the value of a funding signal is knowing to wait for the hire.
Freshness and where the data comes from
Funding is event-dated, which makes it one of the better-behaved signals. Signl stores when the round was announced and, separately, when we first detected it, so you can see the lag rather than trust a freshness claim.
The underlying sources are public: funding announcements and regulatory filings, resolved from a company name to a domain. That resolution step is where funding data usually goes wrong. Two companies share a name, one of them raised, and a naive pipeline attaches the round to the wrong domain. Treat any funding record with no domain on it as unverified.
How to score it
Weight three things independently, and do not multiply them into one number:
| Dimension | What to look at |
|---|---|
| Recency | Days since announcement. Score the three-to-eight week band highest, not day zero |
| Stage fit | Does the stage match where your closed-won deals actually clustered? |
| Use of funds | Does the announcement name a function you sell to? |
A round with no stage attached is common and is not a reason to discard the record. It usually means the source did not publish one, not that the raise was small.
Which ICPs it matters for
Strongest where the purchase is discretionary and the buyer is early: sales tooling, developer tooling, marketing infrastructure, recruiting, anything a company buys once it has decided to grow a function.
Weakest where the purchase is driven by regulation, headcount thresholds or contract renewal dates. A compliance product does not care that a company raised. It cares that they crossed an employee count or entered a market.
The outreach angle it justifies
Not "congratulations on the round", which every other sender opened with.
The angle is the plan, not the money. Reference the specific thing the round is for, and connect it to the problem that shows up when a company does that thing. If the announcement talks about doubling the sales team, the interesting sentence is about what breaks in month two of doubling a sales team, not about the raise itself.
How to query it in Signl
Funding stage and recency are answered together in one search when both are set:
Find UK fintechs that raised a Series A in the last 60 days,
under 200 employees, ranked by ICP score.Behind that, your agent calls:
search_signals({
signalType: "funding",
fundingStage: "series_a",
fundedWithinDays: 60,
country: "GB",
industry: "fintech",
employeeCountMax: 200
})fundingStage accepts values like seed, series_a, series_b, growth and private_equity. fundedWithinDays maxes at 365. country is an ISO-3166 alpha-2 code. Searching costs nothing on any plan.
