What is a Fractional CMO?
A fractional CMO is a part-time chief marketing officer who provides senior marketing leadership on a flexible, contracted basis - typically 10-20 hours per week. Unlike full-time CMOs who command $300,000+ annual salaries plus equity, a fractional CMO delivers the same executive-level strategy and oversight at a fraction of the cost.
Growth-stage startups, SMBs, and companies in transition use fractional CMOs to access senior marketing expertise without the full-time commitment.
How Does a Fractional CMO Work?
The mechanics of a fractional CMO engagement vary by provider and company needs, but the core structure is consistent across the industry.
Retainer-Based (Most Common)
You pay a monthly retainer for a set number of hours - typically 40-80 hours per month. This provides predictable costs and ensures dedicated attention to your business. Retainers range from $5,000-$15,000/month depending on experience and scope.
Project-Based
Some companies engage fractional CMOs for specific initiatives: launching a new product, building a marketing team, or developing a go-to-market strategy. Projects typically run 3-6 months with defined deliverables.
Hourly (Rare)
Hourly arrangements exist but are less common. They work for advisory relationships where the company needs occasional strategic input rather than ongoing leadership.
Time Commitment
Most fractional CMO engagements involve 10-20 hours per week of active work. This includes:
- 2-4 hrs/week Strategy sessions with leadership
- 2-4 hrs/week Team management and 1:1s
- 4-8 hrs/week Hands-on work on priority initiatives
- 2-4 hrs/week Vendor and agency oversight
The key insight: effective marketing leadership is about quality decisions, not quantity of hours. A skilled fractional CMO makes more impact in 15 focused hours than an average full-time hire makes in 50.
What Does a Fractional CMO Actually Do?
The scope varies by company stage and needs, but fractional CMOs typically own these responsibilities.
Strategic Planning & Roadmap
Assesses your current marketing state, identifies gaps, and develops a 6-12 month roadmap aligned with business goals.
- - Market positioning and messaging
- - Channel strategy and budget allocation
- - Goal setting and OKRs
- - Competitive analysis
Team Building & Management
Builds your first real marketing team. This is often the highest-leverage work - hiring the right person multiplies impact for years.
- - Defining roles and writing job descriptions
- - Recruiting and interviewing candidates
- - Onboarding new hires
- - Performance management and coaching
Marketing Operations & Systems
The unglamorous infrastructure that makes everything else work. Companies without marketing ops spend 40% of their time on administrative chaos.
- - CRM and marketing automation setup
- - Analytics and attribution implementation
- - Reporting dashboards and KPIs
- - Process documentation
Performance Optimization
Once systems are in place, focuses on optimization. Individual channel managers optimize their channels. A CMO optimizes the entire portfolio.
- - Campaign performance analysis
- - A/B testing frameworks
- - Budget reallocation based on ROI
- - Conversion rate optimization
Vendor & Agency Management
Most companies work with external agencies for specialized functions. We've seen companies overpay for underperforming agencies for years because no one was watching.
- - Evaluates and selects the right agencies
- - Sets expectations and KPIs
- - Reviews performance and holds agencies accountable
- - Decides when to bring functions in-house
Board & Investor Communications
For venture-backed companies, marketing needs representation in board meetings. This often surprises founders.
- - Prepares marketing metrics for board decks
- - Presents strategy and progress to investors
- - Supports fundraising with marketing materials
- - Translates marketing results into business impact
Fractional CMO vs. Full-Time CMO
This is the core decision. Here's how we advise companies.
| Factor | Fractional CMO | Full-Time CMO |
|---|---|---|
| Monthly Cost | $5,000-$15,000 | $25,000-$35,000+ |
| Annual Cost | $60,000-$180,000 | $300,000-$500,000+ |
| Commitment | Month-to-month or quarterly | 2+ year expectation |
| Flexibility | Scale up/down as needed | Fixed overhead |
| Expertise | Often more diverse (multiple companies) | Deep in one domain |
| Availability | 10-20 hours/week | 50+ hours/week |
| Culture Fit | Less integrated | Deeply embedded |
When Fractional Makes Sense
- You're pre-Series B with under 50 employees
- Marketing budget is under $500K/year
- You need senior expertise fast - hiring takes 3-6 months
- You're in transition - post-acquisition, pivoting, or testing new markets
- Marketing is important but not existential
When Full-Time Makes Sense
- Marketing is your primary growth lever and needs constant executive attention
- You have a large team (10+ marketers) that needs daily leadership
- Board/investors expect a dedicated CMO for credibility
- You've validated the strategy and need someone to own execution at scale
Most companies should start fractional and graduate to full-time when the evidence supports it. We've helped multiple clients hire their full-time CMOs - and stayed on to support the transition.
Fractional CMO vs. Agency vs. Consultant
These three options get confused constantly. Here's the breakdown.
| Factor | Fractional CMO | Marketing Agency | Marketing Consultant |
|---|---|---|---|
| Role | Strategic leadership | Execution | Advisory |
| Ownership | Owns outcomes | Owns deliverables | Owns recommendations |
| Integration | Part of your team | External partner | External advisor |
| Scope | Full marketing function | Specific channels/services | Specific problems |
| Typical Cost | $5K-$15K/month | $3K-$50K/month | $200-$500/hour |
| Team Building | Yes | No | No |
The Hybrid Approach
The most effective model for many companies combines a fractional CMO with specialized agencies:
- 1. Fractional CMO sets strategy, manages vendors, and handles high-level decisions
- 2. Agencies execute on specific channels (paid media, PR, content production)
- 3. In-house team (if any) handles day-to-day operations and company-specific work
At Novastacks, we often work this way. We serve as the fractional CMO and bring in specialized partners for channels where dedicated expertise beats generalist execution.
How Much Does a Fractional CMO Cost?
Pricing varies significantly based on experience, hours, and scope. Here's what we see in the market.
Entry
/month
20-30 hours/month
10-15 years experience, strong in one domain
Mid-Market
/month
30-50 hours/month
15-20 years experience, multiple company successes
Senior
/month
40-60 hours/month
20+ years experience, enterprise/IPO track record
Cost vs. Full-Time CMO
| Item | Full-Time CMO | Fractional CMO |
|---|---|---|
| Base Salary | $250,000-$350,000 | - |
| Equity | 0.5-1.5% | - |
| Benefits | $30,000-$50,000 | - |
| Recruiting Costs | $75,000-$100,000 | - |
| Retainer | - | $60,000-$180,000/year |
| Total Year 1 | $400,000-$600,000+ | $60,000-$180,000 |
You're looking at 3-5x cost savings - and that's before accounting for the flexibility to scale up or down as business needs change.
Signs Your Company Needs a Fractional CMO
Not every company needs senior marketing leadership. Here's how to know if you're ready.
You Need a Fractional CMO If:
- Marketing spend is growing but results aren't keeping pace
- You're hiring marketers but don't know who to hire first
- Agencies are running unsupervised and you're not sure if they're performing
- Product is strong but messaging and positioning feel wrong
- CEO is spending 10+ hours/week on marketing decisions
- You have marketing channels working but can't prioritize investment
- Fundraising is coming up and marketing metrics aren't investor-ready
You Don't Need a Fractional CMO If:
- You're pre-product-market-fit - focus on product, not marketing leadership
- Marketing budget is under $100K/year - invest in execution, not strategy
- You already have a strong marketing leader - don't add overhead
- You want someone to run Facebook ads - hire a specialist, not a CMO
Company Stage Triggers
| Stage | Signal | Fractional CMO Fit |
|---|---|---|
| Seed | Finding PMF | Usually too early |
| Series A | Scaling initial traction | Good timing - set foundations |
| Series B | Building repeatable growth | Ideal - build team and systems |
| Series C+ | Scaling proven playbook | May need full-time CMO |
How to Hire a Fractional CMO
The hiring process matters. Here's what to look for and how to evaluate candidates.
What to Look For
Experience Alignment
- - Have they worked at companies similar to yours (stage, industry, business model)?
- - Do they have a track record of the specific results you need?
- - Have they managed teams and budgets at your scale?
Working Style Fit
- - Are they strategic or hands-on (or both)?
- - How do they communicate - async, meetings, Slack?
- - Can they work at your pace?
Availability
- - Do they have capacity for your needs?
- - How many other clients do they serve?
- - What's their response time commitment?
Red Flags to Avoid
- Overpromising - "I'll double your leads in 90 days" without knowing your business
- No recent experience - The marketing landscape changes fast
- Too many clients - If they have 10 clients, you're getting 4 hours/week
- No execution mindset - Strategy without execution is just consulting
- Poor references - Always check references with former clients
Onboarding Best Practices
The first 30 days determine success:
Week 1: Immersion

Week 2: Assessment

- - Identify quick wins and strategic priorities
- - Draft initial observations and recommendations
Week 3-4: Roadmap

FAQ: Fractional CMO Questions Answered
A fractional CMO is an embedded marketing leader who becomes part of your team, owns outcomes, and manages other marketers. A marketing consultant provides external advice on specific problems without ongoing ownership. Fractional CMOs attend leadership meetings, manage budgets, and hire team members. Consultants deliver recommendations and move on.
Most fractional CMO engagements involve 10-20 hours per week, or 40-80 hours per month. This is enough time for strategic leadership, team management, and oversight of key initiatives. The exact hours depend on company needs, team size, and scope of work. Some engagements start at 10 hours and scale up as needs grow.
Yes. Team building is one of the most valuable functions a fractional CMO provides. They define roles, write job descriptions, recruit candidates, conduct interviews, onboard new hires, and provide ongoing management. Many companies engage fractional CMOs specifically to build their first real marketing team before transitioning to a full-time CMO.
SaaS, B2B services, e-commerce, and professional services see the strongest fit. Any industry where marketing is a significant growth driver but the company isn't large enough for a full-time CMO can benefit. Technology startups, healthcare companies, and financial services firms are common users. The model works less well for capital-intensive industries where marketing is a minor function.
Engagements typically run 6-18 months. The first 3-6 months focus on strategy development, team building, and foundational systems. The following months focus on optimization and scaling. Some companies transition to full-time CMOs after 12-18 months; others continue with fractional leadership indefinitely because the model works well for them.
These solve different problems. A fractional CMO provides strategic leadership and manages your overall marketing function. An agency executes specific channels or campaigns. Many companies use both: a fractional CMO sets strategy and oversees agencies, while agencies handle specialized execution (paid media, PR, content production). If you need leadership, hire a fractional CMO. If you need more hands, hire an agency.
Results vary by company situation, but typical outcomes include: clearer marketing strategy and roadmap, improved marketing team performance, better vendor and agency results, more efficient marketing spend, stronger marketing metrics for investors, and foundation for scaling. Most companies see measurable improvement within 90 days. The best predictor of results is the quality of the fractional CMO and the company's commitment to implementing recommendations.
