'Fractional Head of Growth' has become a real category in 2026 — distinct from fractional CMO and fractional CRO, with its own engagement model and price point. Here's what it actually is, who it's for, and how to think about hiring one.
A fractional head of growth is a senior growth operator (typically 8-15 years of PLG, B2B SaaS, or DTC experience) embedded part-time with a company to architect and run their growth motion. Distinct from fractional CMO (which is broader, more strategic) and fractional CRO (which is more sales-focused). Typical engagements: $8K-$20K/month, 12-month commitments, 1-2 days/week. Best fit: $1M-$20M ARR companies with product-market fit who need to scale acquisition without hiring a $300K full-timer.
The fractional head of growth role focuses specifically on the growth function: acquisition, activation, retention, and expansion. It sits between marketing and product, and increasingly between marketing and sales.
Typical scope of a 12-month engagement:
• Growth strategy and prioritization (which channels, which experiments, which segments)
• Acquisition channel architecture (paid, organic, partnerships, content, community)
• Activation and onboarding optimization (especially PLG)
• Retention and expansion programs
• Growth team hiring and structure
• Reporting and dashboards that connect growth work to revenue
What it's NOT: brand work, broad marketing leadership across all functions, sales team management. Those are CMO or CRO scope.
Same level (senior), different scope.
Fractional CMO is broader: positioning, brand, demand gen, content, PR, team leadership, board credibility. Owns all marketing.
Fractional head of growth is narrower and deeper: acquisition and activation mechanics, growth experiments, channel optimization, retention. Often more quantitative.
When to pick which: if your bottleneck is 'we don't have a marketing strategy,' you need a CMO. If your bottleneck is 'we have a strategy but our growth channels aren't working,' you need a head of growth. Many companies eventually need both. Full comparison →
Different functions entirely.
Fractional CRO owns revenue: sales, sales ops, customer success, sometimes marketing. Heavy on sales motion design, comp structure, deal review, pipeline forecasting.
Fractional head of growth owns growth: acquisition and activation. Heavy on channel mechanics, experimentation velocity, conversion optimization.
They overlap in middle-funnel work (pipeline efficiency, lead quality, sales/marketing alignment) but are different jobs. Don't ask a fractional CRO to fix your paid acquisition; don't ask a fractional head of growth to redesign your sales motion.
Three conditions should all be true:
1. You have product-market fit. Pre-PMF, you need product iteration, not growth optimization. A fractional head of growth at the wrong stage will optimize a leaky bucket.
2. You have $1M-$20M ARR. Below that, you don't have the budget or volume for meaningful experimentation. Above that, you usually need a full-time head of growth.
3. Your growth has plateaued or your CAC has crept up. Something stopped working and you can't figure out what. This is where senior growth experience pays for itself.
Fractional head of growth typically runs $8K-$20K/month for 1-2 days/week. Variance drivers:
• Stage: $1M-$5M ARR engagements lean toward $8K-$12K. $10M-$20M ARR engagements lean toward $14K-$20K.
• Scope: Strategy + light execution at the lower end. Strategy + heavy execution + team management at the higher end.
• Industry expertise: Operators with specific PLG, marketplace, or DTC experience charge premium for fit.
Compare to: full-time VP Growth at $250K-$350K base + equity ($350K-$500K all-in). Fractional is 30-50% of full-time cost for senior-level work.
Typical engagement structure for a high-quality fractional head of growth:
• Weeks 1-4: Diagnostic. Audit current growth motion, identify the 2-3 highest-leverage opportunities, write up a 90-day plan.
• Weeks 5-8: Quick wins. Ship 2-3 things that move metrics in 30 days — usually channel optimization, conversion tweaks, or experiment infrastructure.
• Weeks 9-12: Architecture. Set up the systems (experimentation framework, reporting, channel infrastructure) that will keep producing wins after the diagnostic is forgotten.
• Quarter 2+: Compounding work. Channel scaling, team hiring, larger experiments. This is where 12-18 month engagements pay off.
Choose fractional when:
• Pre-$10M ARR (can't justify $400K+ all-in for full-time)
• You need senior judgment for a defined period (6-18 months) and don't want a long-term commitment
• You want a senior operator who's seen multiple growth motions, not just one company's
• Your full-time head of growth left and you need to fill the gap while hiring
Choose full-time when:
• $20M+ ARR and growing
• You need deep institutional knowledge that compounds over years
• Your growth motion is unique enough that contextual knowledge is the limiting factor
• You can afford $350K-$500K all-in
