A fractional CMO is a senior chief marketing officer who works with a business part-time to set marketing strategy, positioning and budgets, and to lead the team or agencies that deliver it. It gives growing businesses board-level marketing leadership without the cost of a full-time CMO.
What it means
A fractional CMO is responsible for marketing outcomes rather than individual campaigns. They define the target market, proposition and brand, build the go-to-market plan, set marketing KPIs linked to pipeline and revenue, and manage the people and agencies who execute.
They work closely with sales leadership so that marketing activity produces qualified opportunities rather than just activity metrics.
When you need one
Businesses usually hire a fractional CMO when growth has plateaued, marketing spend is not clearly linked to revenue, agencies lack direction, or the company is entering a new market or launching a new proposition. Leadership Services provides fractional CMOs from its bench of senior directors, from £1,795 per month.
Frequently asked questions
What is the difference between a fractional CMO and a marketing agency?
An agency delivers specific services such as paid media, SEO or design. A fractional CMO sits inside the leadership team, decides what marketing should achieve, chooses which channels and agencies to use and holds them to account. Many businesses use both, with the CMO directing the agency.
Is a fractional CMO the same as an interim CMO?
Not quite. An interim CMO usually works full-time for a fixed period, often to cover a gap or lead a major change. A fractional CMO works part-time on an ongoing basis. The fractional model suits businesses that need senior leadership but not five days a week.
