Case studies

Six hires,
the same starting point:
no one was responding any more.

Campaigns run by the Ads & HR Lab team between 2023 and 2025, before the self-service launch. The engine is the same; budgets and local areas are specific to each case.

Six hires

The role, the area, the result.

Every campaign with its context and figures. Nothing retouched.

What they have in common

None of these hires started with a job posting.

In all six cases, the candidates weren't looking. They came across an offer for a job they already do, in an area where they already live, and replied in two fields. That's the only thing I do.
