Fractional head of growth vs an agency: which one a startup needs
Updated 9 November 2026 · Written by Reyansh Juneja and Naman Dhiman, the co-founders of SOVE7GN, who run inbound, midbound and outbound for founders
A fractional head of growth sets strategy and manages the people doing the work, usually for 10 to 20 hours a week. That fits a startup that already has people executing; if nobody on your team posts, follows up or sends outreach every day, a fractional leader will write a good plan that nobody runs, and what you need first is a team that executes daily.
Short answer: hire a fractional head of growth or fractional CMO when you have two or more people doing growth work who need direction, or when you need positioning and channel decisions made before a full-time hire. Hire an execution team when the work itself is not getting done. MarketerHire, which places fractional marketers, puts fractional CMO retainers at $3,000 to $15,000 a month, with $5,000 to $10,000 typical for Series A to B companies.
What does a fractional head of growth do?
A good one does the thinking a startup without a growth leader skips:
- Picks the buyer and the two or three channels worth trying.
- Sets the targets: calls, pipeline, cost per meeting.
- Writes or approves positioning and messaging.
- Hires and manages the people or agencies doing the work.
- Reviews results every week and moves budget.
- Reports to the founder and the board.
What they usually do not do is the daily work itself: writing today's posts, replying to comments, emailing the person who just visited your pricing page, sending fifty personal cold messages. At 10 to 20 hours a week, there is no room for it.
How much does a fractional CMO or head of growth cost?
We could not find a published survey of fractional head of growth rates specifically. The closest data is for fractional CMOs, and most of it comes from firms that sell fractional services. The clearest example, checked November 2026:
| Measure | Figure | Source |
|---|---|---|
| Monthly retainer | $3,000 to $15,000 | MarketerHire, April 2026 |
| Typical for Series A to B | $5,000 to $10,000 a month | Same |
| Hourly rate | $150 to $350 | Same |
| Hours per week on retainer | 10 to 20 | Same |
Treat these as one vendor's view of its own market. Then add the cost of whoever executes the plan. If that is a new SDR, the Bridge Group's 2025 report puts median on-target earnings at $80K a year, before benefits and tools. We break that down in how much an SDR costs.
Fractional head of growth vs agency: what is the real difference?
The difference is not seniority or price. It is who does the daily work.
| Growth work | How often it must happen | Fractional head of growth | Execution team or agency |
|---|---|---|---|
| Choosing buyer and channels | Once, then each quarter | Yes | Input only |
| Setting targets and budget | Monthly | Yes | Input only |
| Writing founder posts | Daily | Rarely | Yes |
| Answering comments and DMs | Daily | No | Yes |
| Emailing warm interest within minutes | Several times a day | No | Yes |
| Building lists and sending outbound | Daily | No | Yes |
| Handling replies and booking calls | Daily | No | Yes |
| Weekly review and changes | Weekly | Yes | Yes |
| Managing other hires | Ongoing | Yes | No |
Read the "how often" column. Most of the work that books calls happens daily. A fractional leader covers the monthly and quarterly rows well and the daily rows not at all. That is fine if you have people for the daily rows. It is a problem if you do not.
When is a fractional head of growth the right call?
Be fair to the option. It is the right call when:
- You have two or more people doing growth or marketing work with no one directing them.
- You are about to hire a full-time head of growth and want someone to set the plan and help hire.
- Positioning is the real problem: buyers do not understand what you sell.
- Your board wants a growth plan and you have no one senior to write it.
- You already use agencies and need someone to manage them. If you are still choosing one, the questions in how to vet a B2B lead generation agency are the ones a good fractional lead would ask on your behalf.
It is the wrong call when you are a founder-led startup with no SDRs, no marketer and nobody posting. Then the plan is not the gap. The hours are.
Can you combine a fractional leader and an execution team?
Yes, and for a startup that has raised a Series B with a few marketers, that can be the best setup: a fractional leader sets direction and an execution team runs it. For a smaller seed or Series A team where the founder still sells, the founder usually plays the strategy role already. What is missing is the daily execution.
That is what SOVE7GN GTM does. We run inbound (daily founder posts on X and LinkedIn), midbound (warm interest answered within minutes) and outbound (personal cold messages on email, X and LinkedIn) and book the calls. The founder approves posts in Slack and keeps the strategy. If you are comparing this with a fractional quote, book a 30-minute call and we will share pricing there.

What should you ask a fractional head of growth before hiring?
- Who will do the daily work you plan, and how many hours a week will you personally put in?
- Which channel would you cut first for a company like ours, and why?
- What would you measure in week 2, week 6 and week 12?
- Have you run outbound and founder content for a B2B startup at our deal size, and can we speak to that founder?
- What do you hand over when you leave?
Questions people ask
What does a fractional head of growth do?
They set growth strategy part-time: choose the buyer and channels, set targets, approve messaging, manage the people or agencies doing the work, and review results weekly. They usually work 10 to 20 hours a week and do not do the daily posting, follow-up or outreach themselves.
Is a fractional CMO worth it for a SaaS startup?
It is worth it when you have people executing who need direction, or when positioning is unclear. It is less useful for a founder-led startup with no one doing the daily work, because the plan will not get run.
Fractional head of growth vs agency: which should I choose?
Choose by who does the daily work. If you have people for it, a fractional leader can direct them. If you do not, an execution team or agency fills the bigger gap, and the founder can keep the strategy.
How much does a fractional head of growth cost?
There is little published data for the head of growth title. For fractional CMOs, MarketerHire puts retainers at $3,000 to $15,000 a month and $5,000 to $10,000 for Series A to B companies.
How many hours does a fractional head of growth work?
Retainers are typically 10 to 20 hours a week, according to MarketerHire. That is enough for planning, managing and reviewing, but not for daily execution.
