Choosing a Model
Fractional CMO vs. Agency vs. Full-Time CMO
The three common ways to get senior marketing help are a fractional CMO, a marketing agency, and a full-time CMO. A fractional CMO gives you senior leadership and strategy part-time, at a fraction of full-time cost. An agency executes campaigns but doesn't own your strategy. A full-time CMO gives you a dedicated leader but costs $250K+ plus equity. For most founder-led startups and SMBs, a fractional CMO is the best fit — and often leads the agencies too.
How the three models compare
Fractional CMO — a senior marketing leader, part-time. Owns strategy and execution oversight, leads your team and vendors, scoped to outcomes. Best when you need seniority without full-time cost.
Marketing agency— an outside team that executes campaigns (paid, creative, content). Good for production capacity, but it doesn't own your strategy and its priorities are its own. Usually staffed with junior-to-mid talent.
Full-time CMO — a dedicated executive fully inside your business. The right call at scale, but $250K+ in salary plus benefits and equity, and often overkill before you have a marketing team to lead.
Cost, seniority, and ownership at a glance
- → Cost:Fractional and agency are both a fraction of a full-time CMO; a fractional CMO adds senior strategy that an agency doesn't.
- → Seniority: Fractional CMO and full-time CMO are senior leaders; agencies vary and usually skew junior on the day-to-day.
- → Ownership: A CMO (fractional or full-time) owns your marketing strategy; an agency owns its deliverables, not your business outcomes.
- → Speed to value: A fractional CMO starts fast and flexes with you; a full-time hire takes a search; an agency needs onboarding and management.
How to choose
Choose a fractional CMO when you need senior direction and someone to lead the work, but aren't ready for a full-time executive — the most common case for founder-led startups and SMBs.
Add an agency when you have strategy and need production capacity in a specific channel. Ideally your fractional CMO manages it.
Hire full-time once marketing is large and central enough to need a dedicated executive building and leading a team every day.
The AI-native wrinkle
One thing has changed the math: an AI-native fractional operator now covers far more ground than the model used to. Matt is genuinely AI-native — he solo-built a live production app (BetLoopr, 60,000+ lines of code) and ranks top 10% globally on Lovable — so a single fractional engagement delivers content at scale, faster experimentation, and custom tooling that used to require a whole team plus an agency.
Frequently asked questions
- Is a fractional CMO better than an agency?
- They do different jobs. A fractional CMO is a senior leader who owns your marketing strategy and can lead the agencies executing against it; an agency is a vendor that executes campaigns. If you need senior direction and ownership, a fractional CMO is the better fit — and often manages the agency too.
- How much does a fractional CMO cost vs. a full-time CMO?
- A full-time CMO typically costs $250K+ in salary plus benefits and equity. A fractional CMO is a fraction of that, scoped to a monthly retainer or a defined outcome, because you're buying part of a senior leader's time rather than a full-time hire.
- When should a startup switch from a fractional to a full-time CMO?
- When marketing has grown large and central enough to need a dedicated executive leading a full team day-to-day. Until then, a fractional CMO usually delivers the seniority you need without the fixed overhead — and can help you hire and onboard the eventual full-time leader.
- Can a fractional CMO also manage our existing agencies?
- Yes — that's one of the most common reasons to hire one. A fractional CMO sets the strategy and directs the agencies and internal team executing against it, so the spend is coordinated toward a clear outcome instead of running in silos.
