When finance and recruiting report different headcount numbers, the real cost isn't the discrepancy. It's the credibility both teams lose in the room where it surfaces.
Finance freezes 10 roles in March and doesn't tell recruiting. Recruiting works the pipeline anyway, gets shut down, then the roles unfreeze in May, and the pipeline is cold.
Cold-starting adds a month to the hire cycle. That's the tax a recruiting tracker can't see coming.
AI is genuinely replacing people in one function: customer support, where the work is finite. Even there, Klarna reversed course 15 months later. Everywhere else, the work is infinite, and five of the six major tech companies grew. The headline hides a reshape, not a cut.
"We already built this" is the most common objection to a headcount planning platform. It is usually true, and the model is usually good. That isn't the part that fails.
