The short version: A fractional CMO gives you senior strategy part-time ($5,000 to $15,000/mo). A growth agency gives you a full execution team ($3,000 to $15,000/mo). A full-time VP of growth gives you one dedicated internal owner ($200,000 to $300,000/yr fully loaded). They solve different problems: judgment, execution breadth, and dedicated ownership respectively. The common mistake is choosing on cost and ending up with strategy but no hands, or execution with no direction. Many growth-stage companies pair a fractional CMO with an agency and skip the VP until later.
Three options, three different problems they solve, and a lot of confusion about which is which. Here is the clean three-way comparison, including the real cost of each and how they combine.
A conflict to flag: we operate as both a growth agency and, for some clients, a fractional growth leadership engagement. So we sit inside two of these three boxes. The framework below is still the one I would give a founder weighing all three honestly.
Fractional CMO vs Growth Agency vs Full-Time VP: What’s the Difference?
A fractional CMO is a senior marketing leader working part-time for strategy and direction. A growth agency is an external team that executes across paid, creative, conversion, and lifecycle. A full-time VP of growth is one dedicated executive who owns the function internally. The fractional CMO is judgment, the agency is reach, and the VP is ownership.
The mistake is treating them as three prices for the same thing. They are three different capabilities. A fractional CMO with no execution team is direction with no hands. An agency with no internal owner is execution with no accountable strategy. A VP alone is one person’s range against a multi-channel problem.
| Dimension | Fractional CMO | Growth agency | Full-time VP |
|---|---|---|---|
| Brings | Senior strategy, part-time | Execution across channels | Dedicated ownership |
| Typical cost | $5k to $15k/mo | $3k to $15k/mo | $200k to $300k/yr loaded |
| Ramp | Days | Days to weeks | 3 to 6 months |
| Commitment | Flexible | Flexible | Fixed, long-term |
| Best for | Direction gap | Execution gap | Scale with steady workload |
How Much Does Each One Cost?
A fractional CMO costs $5,000 to $15,000 a month depending on time commitment. A growth agency costs $3,000 to $15,000 a month depending on scope. A full-time VP of growth costs $200,000 to $300,000 a year fully loaded. That counts salary, equity, benefits, tools, and a 3-to-6-month ramp. That range tracks the market: salary data from Built In shows a VP of Marketing averages $201,971 in base pay and $251,161 in total compensation, before equity, benefits, tools, and ramp.
The cost shape matters as much as the amount. The fractional CMO and the agency are flexible operating expenses you can scale up or down as needs change. The VP is a fixed commitment with a long ramp. It’s the right bet only when the workload is large, steady, and central enough to justify it. We break the agency-versus-hire side of this down further in growth agency vs in-house hire.

Book a Free Strategy CallWhen Should You Combine a Fractional CMO With an Agency?
Combine a fractional CMO with a growth agency when you need senior direction and execution breadth but cannot yet justify a full-time VP plus an internal team. The fractional leader owns strategy and priorities part-time; the agency runs the channels. Together they cover the whole job for less than a single loaded VP salary.
This pairing is the practical sweet spot for many companies between $5M and $50M in revenue. It avoids the two failure modes of going all-in on one box: a fractional CMO with no team to execute the plan, or an agency running hard with no internal owner setting direction. The key is that both work from one shared plan, not two competing ones.

So Which Should You Hire?
Hire a fractional CMO when the gap is senior direction. Hire a growth agency when the gap is execution. Hire a full-time VP when growth is central, the workload is steady, and you can justify the fixed cost and ramp. When the gap is both direction and execution and the budget is growth-stage, pair a fractional CMO with an agency and revisit the VP later.
One rule to leave with: do not shop these three on price. Shop on which capability you are missing. The cheapest option that solves the wrong gap is the most expensive choice you can make.
