Hiring signals explained: what actually predicts a hire
Job ads, funding rounds, tech-stack changes, leadership hires — which signals actually matter for recruitment BD?
Not all signals are equal
Every BD tool now advertises 'signals'. The word has become meaningless — it covers everything from a company posting a job to a CEO tweeting. If you want reply rates that pay for your tooling, you need to know which signals actually correlate with a placement.
We ranked the six most common signals on 12 months of recruitment outreach data across our customer base.
The tier list
Tier 1 (highest conversion): a live job ad for the exact role, posted in the last 14 days, by a hiring manager you can identify. This is the single strongest signal — nothing else comes close.
Tier 2: multiple open roles in the same team (indicates hiring pressure), a leadership hire in the last 90 days (new leaders always hire their own team), or a recent funding round with allocated hiring budget.
Tier 3: tech-stack detection, new office announcement, press mention of expansion. Useful for warm-up sequences but weak as a standalone trigger.
How to combine them
The best-converting outreach in our dataset combines a Tier 1 signal (a specific role) with a Tier 2 signal (context: funding, expansion, new leader). Something like: 'Saw you posted the Head of Data role two weeks ago, and with the Series B closing in April I imagine building out the analytics team is the priority.' That first line is grounded in three data points a recruiter would previously have spent 20 minutes assembling.
