A previously missing founded year was populated.

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

## Why it matters

Often a data cleanup, but worth flagging. Adding a founded year is typically profile maintenance rather than a strategic event, low intensity, but it can indicate someone is actively grooming the company page.

## How to read it

<CardGroup cols={1}>
