Do I need a fractional CMO or a growth marketer for my startup?
If your company has product-market fit and needs to build a repeatable go-to-market motion — you need a fractional CMO. If you have a go-to-market strategy and need someone to execute campaigns — you need a growth marketer. The most common mistake is hiring a growth marketer when you actually need strategic marketing leadership. Growth marketers optimize; fractional CMOs build the strategy they optimize against.
When do investors expect CMO-level marketing?
Most Series A investors expect to see C-suite marketing leadership in place or a clear plan to hire one within 12 months of closing. Series B investors typically require it. A fractional CMO satisfies that requirement immediately while you build toward a full-time hire — and can help you write the job description, run the search, and evaluate candidates when you're ready to make the transition.
What should a fractional CMO deliver in the first 90 days for a startup?
In the first 90 days, a fractional CMO should deliver: a validated ICP with firmographic and psychographic definitions, a positioning and messaging architecture, a prioritized channel strategy with budget allocation, a demand generation calendar, a marketing-sales alignment protocol (SLA, MQL definition, handoff process), and a metrics dashboard tied to revenue. If you don't have these after 90 days, you hired the wrong person.
