The CFO view

The math your CFO will actually run

Lower hiring costs, faster ramp-up, and new business sourced through former employees all show up on the bottom line. A managed alumni network makes that return measurable, so you can report it with confidence.

Citations refer to published research and to primary interview studies (Blueshift Research, 2021; IDC, 2020). Some foundational figures date to earlier studies; we refresh them as the literature does.
