Fractional CMO vs marketing agency
A fractional CMO owns marketing strategy, hires the team, and reports to the CEO. A marketing agency executes campaigns and creative under a strategy. Most Series A companies need both — a fractional CMO to set direction, an agency to execute paid, creative, or SEO at scale.
What each does
A fractional CMO sets positioning, allocates budget, hires marketers, owns the funnel, reports to the CEO and board. A marketing agency runs paid media, produces creative, executes SEO, or manages content pipelines — under a strategy that someone else set.
When a fractional CMO wins
You have no marketing leader. Positioning is unclear. You cannot articulate ICP or messaging. You need to hire an in-house team. You need one person accountable for marketing at the board level.
When an agency wins
Strategy and positioning are clear. You need scaled execution — paid, creative, SEO, or content. You already have an internal marketing lead who can brief and QA the work.
The hybrid model most Series A companies run
Fractional CMO at 25 hours per month ($10,000 to $12,000) plus a specialist paid-media agency ($8,000 to $20,000) plus one in-house marketer ($8,000 to $12,000 fully loaded). Total: $26,000 to $44,000 per month for a full marketing function — 40 to 60 percent cheaper than a full-time CMO plus in-house team.
Cost comparison
Fractional CMO: $6,000 to $20,000 per month. Full-service marketing agency: $10,000 to $50,000 per month. Specialist agency (paid, SEO, or creative only): $5,000 to $25,000 per month. In-house senior marketer: $12,000 to $18,000 per month fully loaded.
Common mistakes
Hiring an agency without a strategy — they will execute the wrong things efficiently. Hiring a fractional CMO and expecting them to execute creative — they will manage, not produce. Paying full-CMO rate for a former agency owner who has never held an in-house CMO title.

Frequently asked questions
Can a fractional CMO replace an agency?
For strategy, brand, and leadership: yes. For scaled paid media, creative production, or technical SEO: no. Most companies use both.
Which do I hire first?
The fractional CMO. Strategy before execution. An agency briefed by a founder often produces the wrong output.
