The signals that hold up
Ranked roughly by how reliably they precede a purchase, and by how checkable they are:
- A cluster of roles in one function. Several openings in one team within a fortnight means a budget was approved and a deadline exists. It is the clearest statement of intent a company makes in public.
- A new function head. Someone arriving to run a department reconsiders its tools early, and the change is usually announced.
- A funding round. New capital is followed by spending, and the round is public in most jurisdictions.
- A regulatory deadline that applies to them. A rule with an effective date creates work with a date attached, which is a rare kind of certainty.
- A technology change visible in their own job postings. A company hiring for a stack it did not use last year is migrating, and migrations buy things.
- Expansion into a new location, stated in postings or announcements.
The signals that mostly do not
Website visits from a company IP, generic news mentions, social engagement and most third-party intent scores share a problem: they are consistent with a dozen explanations, only one of which is a purchase. Somebody reading your blog might be a buyer, a competitor, a candidate or a student.
This does not make them worthless. It makes them a tiebreaker rather than a trigger. Use them to order a list you built from harder evidence, not to create the list.
A signal is not an opening line
The most common mistake with buying signals is quoting them back. "I saw you are hiring three data engineers" is not an insight; the recipient posted those roles and is aware of them. The signal tells you who to contact and when. The message still has to say something useful about their situation.
Better: use the signal to choose the subject, not to be the subject. If they are hiring data engineers, the message is about the problem those engineers will hit in month three, and the signal never has to be mentioned.
Timing, and the window
Signals decay. A hiring cluster is most actionable in the first few weeks, while the budget is being spent and before vendors are shortlisted. A funding round has a longer window, typically a quarter or two, because the spending follows the announcement rather than accompanying it. A regulatory deadline works backwards from the date: the useful contact happens when the work is being scoped, not when it is due.
