Follower growth ran sharply above the company's recent baseline.

## When it fires

<Card title="Trigger condition" icon="bolt">
  Current-crawl follower growth rate ≥ 3× the rolling average of the previous 6 crawls.
</Card>

## Magnitude

By definition a high or hyper event, the 3× threshold filters out ordinary growth.

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

## Why it matters

A spike usually means a launch, a viral moment, or a funding announcement worth investigating. It's the sharp, anomalous version of followers\_growth, and it's far more actionable because it marks a specific moment in time rather than a trend.

  <Card title="Time-sensitive">
    The attention window is short, reach out while the company is still in the spotlight.
