Fractional CMO in the United States: when it makes sense and how to choose



"Fractional" is the standard American word for a senior executive who works for a company a fraction of the week. It belongs to the vocabulary of international, VC-backed, English-speaking companies. In France the same model is called Part-time CMO, and iytro created it there in 2019. For days, prices and logistics, read part-time CMO in the United States. This page is about the decision.
A fractional CMO is a member of the leadership team. They own strategy, budget, team and results. What changes compared with a full-time CMO is the number of days, and the fact that you can adjust it.
Full-time CMO. The right choice when the company needs a marketing executive five days a week and can wait for the search. In the US that means a competitive talent market and a package with salary, bonus and usually equity. A fractional CMO starts sooner, you pay only for the days you use, and there is no long-term commitment.
Agency. The US has agencies for every channel and every budget. An agency works to a brief. Sitting in your leadership team, arbitrating between channels and managing your people are outside its role. A fractional CMO writes the brief and holds the agency to it.
Freelancer. A freelancer is usually a specialist in one discipline, hired for a defined output. A fractional CMO is accountable for the whole function. With iytro there is also a range of senior profiles behind the engagement: CMO, Head of Growth, Brand Director, Product Marketing, CRM, Content, Field and Partner Marketing, Marketing Ops.
For a European company, there is a fourth option: running the US from head office. It tends to work until the time difference and the distance from American buyers start slowing decisions. For how one leader covers several home markets, see fractional CMO in Europe, written for European companies expanding to the US and beyond.
An iytro leader is embedded in your team 1 to 3 days per week, or as an interim. The day rate is €1,100 to €1,500, stated in euros. Two days a week is about €10,000 to €12,000 per month. There is no long-term commitment and the volume is adjusted month by month. The model is described on the part-time CMO page.
A typical plan runs in three stages:
iytro has offices in Paris, Barcelona and New York. Its US office is in New York and it has no other office in the country. Elsewhere in the United States, leaders work from New York, on site when needed and remotely otherwise.
iytro has worked with 400+ clients since 2019, 86% of clients recommend it, and it is B Corp certified. Two case studies show the model at work: Qovoltis and Lifen.
Yes. Fractional is the American term. Part-time CMO is the name iytro gave the same model when it created it in France in 2019.
A fractional CMO fits the first phase, when the market has not yet answered and the need is 1 to 3 days a week. A full-time hire makes sense once US marketing needs five days.
iytro has an office in New York and no other US office. Elsewhere in the country, its leaders work on site when needed and remotely otherwise.
