What is a fractional CMO?
A fractional CMO is a senior marketing executive who works with your company part-time, providing the same strategic leadership as a full-time CMO at a fraction of the cost. Engagements typically range from 2 hours/month (advisor) to 2 days/week (part-time CMO) to 3–6 months full-time (interim CMO).
When does a fractional CMO make sense?
Fractional CMOs work best for: post-Seed to Series B startups not yet ready for a full-time CMO; bootstrapped/PE-backed companies that need senior marketing leadership without a $300K+ comp package; companies in transition (between CMOs, post-acquisition, new product launch); and companies that need AI-fluent marketing leadership their current team lacks.
How is David Berkowitz different as a fractional CMO?
David has spent 20+ years building and leading marketing teams across B2B SaaS, hospitality, CPG, and agencies. He runs the 7,000-member AI Marketers Guild, wrote a book on AI marketing, and brings hands-on AI implementation experience — not just strategy decks. He helps companies build AI-native marketing operations that compound.
What does a fractional CMO engagement cost?
Pricing depends on scope. Advisory engagements start at $5K/month. Part-time CMO retainers typically run $10K–$25K/month. Interim CMO engagements are project-priced. We discuss budget on the discovery call so the engagement is structured around your goals — not the other way around.
