Quick answer
An interim CEO steps into a full-time leadership role temporarily — typically during a transition, crisis, or while a permanent CEO is being recruited. A fractional CEO works part-time (often 1–3 days per week) on an ongoing basis, providing senior leadership to companies that do not need or cannot afford a full-time CEO. Both serve companies without permanent CEO leadership, but in very different contexts.
Interim CEOs and fractional CEOs solve different problems. An interim CEO is for acute, full-time leadership gaps that require complete dedication. A fractional CEO is a cost-efficient, ongoing model for companies that need strategic leadership but not a full-time executive. Do not try to use a fractional CEO to fill an interim gap — a company in transition needs full attention, not a part-time arrangement.
