Frequently asked questions
What is a fractional CMO and how does it differ from a full-time hire?
A fractional CMO provides strategic marketing leadership and direction on a part-time or project basis, typically 10-20 hours weekly, without the salary, benefits and overhead of a full-time executive. This model suits growth-stage companies needing senior expertise but lacking the budget or scope for a full-time chief marketing officer.
How much should we expect to pay for fractional CMO services?
Fractional CMO pricing ranges from £3,000-£20,000+ monthly depending on scope, company stage and engagement model. Entry-level services start around £4,000-£5,000/month for early-stage startups, whilst integrated execution or premium networks charge £15,000+/month for mid-market and PE-backed firms.
What metrics should we use to evaluate fractional CMO success?
Track qualified lead generation, customer acquisition cost (CAC), pipeline contribution, marketing-influenced revenue, market positioning improvements and internal team development. Establish baseline metrics before engagement begins and review progress quarterly to ensure alignment with business growth objectives.
