A part-time CMO is a senior marketing leader who sits in your management team for part of the week. They own the marketing strategy, the budget, the team and the numbers, as a full-time CMO would, on 1 to 3 days a week. Many people in the UK call the same model a fractional CMO in London. The two terms describe one way of working.
London makes the case for it quickly. Senior marketing talent is expensive and in demand. Hiring a full-time CMO is a long process, with a notice period at the end of it. Many companies need senior judgement now, without having five days of work to give that person. A part-time CMO closes that gap.
iytro leaders work 1 to 3 days per week inside the client team, or as an interim when a seat is empty. The day rate is €1,100 to €1,500. Two days a week comes to about €10,000 to €12,000 per month. These figures are in euros.
There is no long-term commitment. The volume is adjusted month by month: more days during a launch or a fundraise, fewer once the team runs on its own. As a rule of thumb:
London is a fintech centre and a base for a great deal of B2B software, professional services and consumer brands. The model fits several profiles that are common here:
It suits a company less well when marketing needs an executive in the room every day, or when the real need is execution capacity. For that second case iytro has two other offers: 1+1, a small subscription team, and On Demand, a scoped project delivered as a finished asset.
This needs to be said plainly: iytro has no office in London. Its offices are in Paris, Barcelona and New York. iytro leaders work with London companies from those bases, on site when needed and remotely otherwise.
The rhythm is agreed at the start. A setup that works well:
Paris and London are linked by train and sit one hour apart on the clock, so working days overlap almost entirely. Many London teams already work hybrid weeks, and a leader who is in the office on set days fits into that habit.
If you sell on both sides of the Channel, read part-time CMO in Europe to see how one leader runs marketing across several markets.
It starts with a conversation about your situation: stage, team, targets, what has already been tried. iytro then proposes a leader whose background matches the need. The profiles cover CMO, Head of Growth, Brand Director, Product Marketing, CRM, Content, Field and Partner Marketing, and Marketing Ops.
The first weeks generally go to diagnosis: positioning, funnel data, team, tools, budget. The leader then sets a short list of priorities and runs them with your team. Because the volume is adjusted monthly, you can begin with a heavier setup and reduce it once the plan is in motion.
iytro was founded in 2019 and created the Part-time CMO model in France. It has worked with 400+ clients, 86% of clients recommend it, and it is B Corp certified. To see what an engagement looks like, read the Lixo case study and the Mooncard case study.

Yes. The leader is embedded in your team 1 to 3 days a week and directs the people, agencies and budget, in person on on-site days and remotely on the others.
