A fractional CRO is a senior revenue leader who works part-time — typically 2–3 days per week — providing Chief Revenue Officer-level strategic direction and execution leadership. They own the revenue number, align sales and marketing, build the commercial infrastructure, and drive growth. The difference is they do it across multiple companies simultaneously, giving each business access to C-level expertise at a fraction of the full-time cost.
What Does a Fractional CRO Actually Do?
- Revenue strategy — Define the GTM strategy, target market segmentation, and commercial model
- Sales and marketing alignment — Ensure both functions work from the same ICP, messaging, and handoff processes
- Pipeline management — Build and optimise the pipeline generation engine across inbound and outbound
- Team leadership — Coach sales leaders, run pipeline reviews, and set performance standards
- Revenue operations — Ensure CRM hygiene, reporting accuracy, and data-driven decision making
- Board reporting — Provide clear commercial metrics and forecasts to the board and investors

When to Hire a Fractional CRO
- You're between £3M and £30M in revenue and can't justify a £200K+ full-time hire
- You've just raised Series A or B and need to professionalise your commercial function
- Your CEO is still running sales and needs to step back
- You're post-acquisition and need to integrate or restructure the revenue team
- You're between CROs and need interim leadership while you recruit
- Your current sales leader is strong tactically but needs strategic support
How to Find the Right Fractional CRO
The most important factor is fit — not just skills, but experience with your stage, industry, and commercial model. A fractional CRO who's scaled SaaS companies from £5M to £20M is different from one who's restructured enterprise sales teams. Look for:
- Direct experience at your revenue stage and in your industry
- Specific case studies with measurable outcomes
- A structured approach to diagnosis before prescription
- References from CEOs and boards, not just peers
