What is an interim CEO?
The definition, the actual authority, what the role covers week by week, how long mandates run, and where the model does not work.
Direct answer
An interim CEO is an experienced executive appointed to run a company full-time for a defined period, usually three to twelve months, with the same authority as a permanent CEO. The board or controlling shareholder appoints them, and the mandate ends on an agreed date, normally when a permanent successor starts.
The role in practice
What the job looks like.
01
Days 1-14
Cash position, customer concentration, top team assessment, board expectations written down. No restructuring announcements yet.
02
Days 15-45
Stop the losses. Fix the reporting pack so the board sees the same numbers weekly. Decide what gets cut and who stays.
03
Days 46-90
Execute. Commercial engine, pricing, key hires, supplier renegotiation. First measurable movement in the numbers.
04
Final 30 days
Handover pack, successor briefed, open items documented, exit on the agreed date. No trailing dependency on the interim.
Where it does not work
Honest limits.
- The board wants a strategy document, not someone accountable for delivering it.
- Shareholders cannot agree what outcome the mandate is supposed to produce.
- The real gap is a COO or CFO and the board is mislabelling the seat.
- The company needs a decade of relationship building, not a defined outcome.
FAQ
Interim CEO. Definitions and duration.
What is an interim CEO?
An interim CEO is an experienced executive appointed to run a company full-time for a defined period, usually three to twelve months, with the same authority as a permanent CEO. The appointment is made by the board or controlling shareholder and ends on an agreed date, normally when a permanent successor starts.
What does interim CEO mean on an org chart?
It means the person holds full CEO authority but the appointment is time-boxed. In Italy the filed title is usually Amministratore Delegato with powers registered at the Registro delle Imprese. Nothing about the powers is provisional: only the duration is.
What does an interim CEO actually do in the first 100 days?
Weeks one and two: cash, customers, top team, board expectations. Weeks three to six: stop the bleeding, fix reporting, decide what gets cut. Weeks seven to twelve: execute the agreed plan and build the second line. Throughout: a written weekly update to the board so nobody is surprised.
How long do interim CEOs last?
Three to twelve months is the normal range. Under three months there is not enough time to change any number. Past twelve months the role should be made permanent or handed to a hired successor. A gap mandate typically runs six to nine months, matching the length of a permanent CEO search.
Can an interim CEO become the permanent CEO?
Sometimes, and it should be declared up front. If the interim wants the permanent seat they are a candidate, not a caretaker, and will make decisions accordingly. A clean interim mandate states explicitly whether the incumbent is in the running. Mine states that they are not.
What is the difference between a CEO and an interim CEO?
Authority is identical. The difference is tenure, incentive and mandate. A permanent CEO builds a multi-year agenda and owns their own succession. An interim CEO is hired to deliver a specific outcome by a specific date, has no internal career to protect and can therefore make unpopular decisions faster.
Are interim CEOs just caretakers?
Caretaker mandates exist, where the board only wants stability until a successor arrives. Most are not. The typical brief is cash, cost, a stalled integration or a broken commercial engine, all of which require decisions a caretaker would avoid. Agree which of the two you are buying before you sign.
