Every founder I know who hired a CFO post-raise describes the same first week. The CFO asks for the cap table, the model, and the board minutes. Then they go quiet for three days then they come back with a look that says they have found something.

They have always found something.

The thing they find is usually the round itself. Wrong price, wrong structure, wrong precedent baked into the next raise before the ink dried. The founder thought they were hiring financial discipline but they hired a forensic accountant for their own crime scene.

This is not a reason not to hire the CFO. It is a reason to hire them before you price the round.
