The answer depends on three questions. Is the need acute and time-limited? Is it clear what the marketing function should look like permanently? And does the volume of work support a full-time role? If all three answers are yes, hire permanently. In every other case, an interim CMO or a fractional CMO is often the better choice.
I have filled all three roles myself: as Senior Marketing Director in a permanent position, as an interim manager, and as a fractional leader. That is why I know where each format holds up and where it does not.
A permanent hire is right when the company needs a long-term, stable marketing function and already knows what it should look like. The problem is time and risk. A CMO search takes four to six months. A mis-hire at this level costs €250–350K, including severance and lost time. The risk rises when the company cannot yet say exactly what the role should deliver. Then it searches for a person to fit a requirements profile that is no longer right after three months.
An interim CMO fits when the need is acute and the window is fixed: market entry, integration after an acquisition, the launch of a new product category, a go-to-market realignment. The interim takes over the function with a full mandate, typically for six to eighteen months. The interim decides, builds the team, and executes. The difference to a consultant: the interim is accountable for the result.
An example from my work: at a premium tea brand with more than 200 years of history, I led product management for 15 months. After two months an innovation pipeline was in place, and in the end a Senior Product Manager took over. The build-up was time-limited. The permanent role could then be staffed more narrowly than at the start of the search. I documented the full case.
Fractional fits when the challenge is real but does not fill a full-time role. Two to three days per week, mostly three to six months, with a fixed rhythm and clear outputs. There are three situations I know particularly well. Growth comes from the founder team and no longer scales, and a strategic GTM framework is missing. Or an interim engagement has ended and the internal team still needs a phase of support. Or a single area needs leadership, such as a product line, a new market, or a channel.
At a premium nutritional supplement brand with double-digit growth, three months of fractional work were enough: a brand key, a three-year product roadmap, and a tracking system that the team runs on its own afterwards.
The line between interim and fractional is intensity, not quality. Methodology and depth are the same. Interim fits systemic problems, vacancies, and PE transactions. Fractional fits a bounded need.
The check I suggest has three steps. Can the role be described in one sentence, and will the sentence still be right in a year? Then hire permanently. Does the answer depend on a transformation with a beginning and an end? Then interim. Is what is missing mainly a framework that the team will carry afterwards? Then fractional. And if it is unclear where the real problem sits, the diagnostic comes before any staffing decision, for example with Clear Focus in a few weeks.
All three formats are legitimate. It gets expensive when the format does not fit the question.
