What You Get - Frequently Asked Questions
What does a fractional CMO do for companies in this market?
A fractional CMO acts as your Chief Marketing Officer on a part-time basis -- typically 2-3 days per week -- with full executive accountability for strategy, team leadership, budget, and revenue outcomes. They own your entire marketing function and are accountable for pipeline generation and revenue attribution, not just deliverables.
How quickly will I see results?
Most engagements produce measurable outputs within 30 days: a GTM strategy, ICP definition, messaging architecture, and demand generation plan. Pipeline movement typically appears in 60-90 days as campaigns launch. Long-term compounding results build over 6-12 months.
Is there a long-term contract required?
No. Every MarkCMO engagement is month-to-month. There are no long-term contracts, no cancellation fees, and no lock-in. You stay because the results justify it. We offer a free GTM diagnostic before you commit to any paid engagement.
Do I have to sign a long-term contract?
No. Every MarkCMO engagement is month-to-month. There are no long-term contracts, no cancellation fees, and no lock-in clauses. You stay because the results justify it -- not because you are contractually obligated. We offer a free GTM diagnostic before you commit to any paid engagement so you can validate fit before spending a dollar.
How does the engagement start?
Step one is a free 30-minute GTM diagnostic call. We review your current situation, revenue goals, team structure, and the biggest gap between where you are and where you need to be. If there is a clear fit, we outline a 30-60-90 day plan and agree on scope. Most engagements are live within 5-7 business days of the diagnostic call.
