Interim management
We do not sell hours: we sell a role. We temporarily assume a management position with full executive authority during the engagement.
When a company loses a director — finance, operations, compliance — and needs months to find the right replacement, the two usual options are both poor: leaving the position vacant or appointing an internal person who is not ready.
The third option is to hire an interim manager: a senior executive who takes on the role with full responsibility for the required period, relieves the team of uncertainty, defines the definitive profile, and trains the successor.
Our typical commitment is 2 to 4 days per week, over 6 to 18 months. The firm commits and the individual assumes professional accountability. This is not advisory consulting from the outside: it is execution from within.
