What Does a Fractional CMO Do in the First 90 Days?
The short answer: A fractional CMO spends days 1–30 diagnosing what helps and blocks growth, days 31–60 building foundations (priorities, reporting, operating rhythm), and days 61–90 running the function and strengthening the team.
Key takeaways
- Month one is diagnosis, not campaigns.
- By day 30 you should have a prioritised 90-day roadmap.
- By day 60 you should have a reporting view and operating rhythm leadership trusts.
- By day 90 you should have results, a next-quarter plan and a clear recommendation on what comes next.
What is a fractional CMO?
A senior marketing leader who works part-time or on a defined engagement and owns strategy, budget, team direction and accountability, without a full-time executive cost.
Days 1–30: What gets diagnosed?
- Stakeholder interviews across founders, sales, customer success and finance.
- Positioning, ideal customer profile and messaging.
- Channels, spend and conversion from first touch to closed revenue.
- CRM, lead handling and sales handoffs.
- Data quality, team structure and agency relationships.
Deliverable: a plain-language diagnosis and a ranked 90-day roadmap.
Days 31–60: What gets built?
- Sharper positioning and go-to-market priorities.
- Shared funnel definitions with sales.
- A first dashboard covering pipeline, acquisition cost and conversion.
- A planning, testing and review cadence.
- Channel and budget priorities, and clear team roles.
Deliverable: an operating rhythm the team can run.
Days 61–90: How does the fractional CMO lead?
They run weekly priorities and monthly reviews, manage the team and agencies against outcomes, report to leadership in commercial terms, reallocate budget on evidence, and make the case for the next hire.
Deliverable: results against the roadmap and a plan for next quarter.
How do you know it's working?
Look for leading signs: agreed priorities, consistent reporting, shared marketing and sales definitions, and explainable spend. Pipeline and efficiency gains typically follow.
Frequently asked questions
