Definition
What is a Fractional CMO?
A Fractional CMO (Chief Marketing Officer) is a seasoned marketing executive who works with your company on a part-time or project basis—typically 1-3 days per week. You get senior-level marketing leadership, strategic expertise, and proven execution frameworks without the £150,000-£250,000 annual commitment of a full-time CMO.
Think of it as "marketing leadership as a service." Fractional CMOs bring 15+ years of experience scaling companies like yours. They've built marketing engines, hired teams, launched products, and driven millions in revenue. Now they work with 2-4 companies simultaneously, sharing that expertise at a fraction of the cost.
💡
The fractional model works because most companies don't need a CMO five days a week.
Strategic decisions happen weekly, not daily. A fractional CMO spends 2 days per week setting direction, building systems, and coaching your team—then your team executes during the other 3 days. You get the expertise when it matters, without paying for downtime.
Fractional vs Full-Time vs Agency
Understanding the difference is critical to making the right hire:
Fractional CMO
- ✅ Strategic leadership
- ✅ Team building & management
- ✅ Embedded in your company
- ✅ Accountable for results
- ✅ 1-3 days/week commitment
- ✅ £70k-£140k annual cost
Full-Time CMO
- ✅ Strategic leadership
- ✅ Full-time availability
- ✅ Deep company integration
- ✅ Equity alignment
- ❌ £150k-£250k+ annual cost
- ❌ 3-6 month hiring process
Marketing Agency
- ✅ Tactical execution
- ✅ Specialized capabilities
- ❌ Not strategic leadership
- ❌ Vendor relationship
- ❌ Doesn't manage your team
- ❌ Not accountable for strategy
Key insight: Marketing agencies execute tactics (run ads, create content, manage social). Fractional CMOs lead (set strategy, build teams, own results). Many successful companies use both: a fractional CMO to lead, with agencies handling specialized execution.
When to Hire
7 Signs Your Business Needs a Fractional CMO
Not sure if you're ready? Here are the telltale signs it's time to bring in marketing leadership.
1
💸
Marketing Spend with No Clear ROI
You're spending £10k-£50k/month on marketing—ads, agencies, tools—but can't articulate what's working or tie it to revenue. You need strategic oversight to optimize spend and prove ROI.
2
🚧
Founder-Led Marketing Has Hit a Wall
The CEO or founder has been "doing marketing" between product and fundraising calls. It worked for early traction, but now growth has plateaued and the founder needs to focus on their actual job.
3
🎯
You Have a Marketing Team But No Strategy
You've hired 2-4 marketers—maybe a content person, performance marketer, designer—but they lack direction. They're executing tactics without a cohesive strategy or someone making the hard prioritization calls.
4
📈
Post-Product-Market Fit Growth
You've validated PMF and raised Series A or B. Now you need to scale customer acquisition systematically. This is the classic fractional CMO moment: build the marketing engine that takes you from £1M to £10M ARR.
5
🌍
Launching in a New Market or Vertical
Expanding to a new geography (e.g., UK to US), audience segment, or product line. You need someone who's done it before to lead GTM strategy, positioning, and messaging.
6
🤝
Marketing Agencies Aren't Delivering
You've hired agencies for SEO, paid ads, PR—but they operate in silos without strategic alignment. A fractional CMO acts as the "client-side quarterback" to coordinate agency work and drive accountability.
7
💰
You Can't Justify a £200k+ Full-Time CMO
You need senior marketing leadership but don't have the budget, headcount, or workload to justify a full-time executive hire. Fractional gives you 80% of the value at 40% of the cost.
Rule of thumb: If you checked 2+ boxes above, you should be talking to fractional CMOs this week. If you checked 4+, you're already late—marketing leadership should have been your last hire.

Questions to Ask in Interviews
These questions separate strategic CMOs from tactical marketers:
🎯 Strategy & Experience
- • "Walk me through how you scaled marketing at [previous company]. What worked? What didn't?"
- • "What's your approach to developing marketing strategy from scratch?"
- • "How do you prioritize channels when you have limited budget?"
- • "Tell me about a time you pivoted strategy mid-execution. What changed and why?"
📊 Metrics & Performance
- • "What marketing KPIs do you track religiously? How do you define success?"
- • "How do you approach attribution modeling and proving marketing ROI?"
- • "What's an example of a campaign that underperformed? How did you diagnose and fix it?"
- • "What CAC and LTV ratios are healthy for a business like ours?"
👥 Team & Leadership
- • "How would you structure our marketing team? What roles would you hire first?"
- • "How do you manage agencies vs in-house teams?"
- • "Tell me about a time you had to coach an underperforming marketer."
- • "How do you balance being fractional with building deep relationships with the team?"
🔍 Company Fit
- • "What's your experience in [our industry]? What unique challenges does it have?"
- • "How many companies are you currently working with? How do you manage time?"
- • "What would success look like for you in the first 90 days here?"
- • "What red flags would make you walk away from this engagement?"
Red Flags to Watch For
- 🚩 Can't articulate measurable results: If they talk in platitudes without concrete metrics, they're not data-driven.
- 🚩 Overcommitted: Working with 5+ companies means you won't get the focus you need.
- 🚩 One-trick pony: Only done one channel (e.g., just SEO or just paid ads) won't have full-funnel perspective.
- 🚩 Never built a team: If they've only been individual contributors, they lack leadership experience.
- 🚩 Defensive about past failures: Great CMOs own their mistakes and explain what they learned.
ROI & Benefits
Why Hire a Fractional CMO?
The business case for fractional marketing leadership is compelling. Here's why companies make the switch.
50%
Average Cost Savings
Cost Efficiency: 40-60% Savings
Access CMO-level expertise at a fraction of full-time cost. A fractional CMO at £1,000/day for 2 days/week costs £104k annually vs £180k-£250k+ for full-time (salary + benefits + equity + overhead). You save £100k+ while getting the strategic leadership you need.
2-4
Weeks to Impact
Speed to Impact: Start in Weeks, Not Months
Recruiting a full-time CMO takes 3-6 months. Fractional CMOs can start within 1-2 weeks and deliver value immediately with proven playbooks. No 90-day ramp period—they've seen your challenges before and know exactly how to solve them.
15-20
Years Experience
Deep Expertise Across Multiple Companies
Fractional CMOs bring 15-20 years of experience scaling companies like yours. Because they work with 2-4 companies simultaneously, they see what works across different models, markets, and stages. You get cross-pollinated best practices and fresh perspectives.
1-5
Days/Week Flexible
Flexibility to Scale Up or Down
Increase days per week for product launches or fundraising. Reduce during steady-state periods. No long-term employment contracts or severance risk. Engagements flex with your business needs and cash flow.
0-0.25%
Equity Typical
No Equity Dilution
Full-time CMOs at startups expect 0.5-2% equity. At a £50M valuation, that's £250k-£1M in ownership you retain. Some fractional CMOs take small advisory stakes (0.1-0.25%), but most work for cash only.
30
Days Notice
Lower Risk: Try Before You Commit
Start with a 3-month trial engagement. If it works, extend. If not, part ways cleanly with 30 days notice. Much lower risk than hiring a £200k full-time executive who may take 6+ months to exit.
Real ROI Example
A Series A SaaS company hired a fractional CMO at £1,200/day, 2 days/week (£125k annual cost). In 12 months, they:
- ✓Reduced CAC from £4,200 to £2,100 (50% improvement)
- ✓Grew MQLs from 120 to 380 per month (3.2x)
- ✓Increased pipeline by £2.4M annually
- ✓Hired and onboarded 3 full-time marketers
- ✓Built repeatable demand gen engine
- ✓Positioned company for successful Series B
ROI: £125k investment → £2.4M incremental pipeline = 19x return in year one.
