Why it works
A past customer already knows your product, and a new job post for the team that used it says the need is back. That conversation is shorter than one with a new account. On a current customer, the same signal points to a growing team and a chance to upsell.
How to act on it
Trigger win-back, upsell, customer success, or expansion outreach.
