Open job postings jumped sharply above the recent baseline.

## When it fires

<Card title="Trigger condition" icon="bolt">
  `job_count` ≥ 2× the rolling average of the previous 4 crawls.
</Card>

## Magnitude

High by design, the 2× threshold excludes routine hiring.

<Note>
  For the full bucket definitions used across percentage-based signals, see [Magnitude buckets](/buying-signals/concepts/magnitude-buckets).
</Note>

## Why it matters

A hiring spike is one of the strongest near-term budget indicators you'll find. Doubling open roles in a single window signals an aggressive growth push, often funded by a recent raise or a new strategic mandate.

## How to read it

<CardGroup cols={1}>
  <Card title="Aggressive growth">
    Sudden doubling means a company is scaling fast and deliberately.
  </Card>

  <Card title="Often post-funding">
    Hiring spikes frequently follow funding rounds, check for a recent raise.
  </Card>

  <Card title="Equip the wave">
    New hires at scale need onboarding, tooling, and enablement, all budget lines.
  </Card>
</CardGroup>

## Outreach playbook

<Tip>
  High-priority alert. Look for a co-occurring funding signal to confirm the budget source.
