Revenue Doesn't Lie. Find What's Breaking It.
By Mark Gabrielli · Fractional CMO & COO · Last updated: May 2026Scattered marketing. Broken operations. No one connecting the dots. I find what's broken, fix what matters, and build the systems that let you scale — without the $300K+ full-time executive cost.
MarkCMO offers fractional CMO and fractional COO services for growth-stage B2B companies. Engagements are month-to-month with no long-term contracts. The service model covers full marketing strategy ownership -- ICP definition, demand generation, brand positioning, team leadership, and revenue attribution -- at 20 to 40 percent of the cost of a full-time executive hire. First results typically appear within 30 days.
Three Steps. Zero Risk.
Every engagement starts the same way, with radical clarity on what's actually holding your business back.

Fractional C-Suite vs. Every Other Option
Companies at $1M to $50M revenue have four choices for senior strategic leadership. Here is what each actually delivers.
| Fractional C-Suite | Full-Time Executive | Marketing Agency | Consultant | |
|---|---|---|---|---|
| Monthly Cost | $8K - $25K/mo | $20K - $40K/mo + benefits + equity | $5K - $30K/mo | $5K - $25K/mo |
| Time to Start | Days | 3 - 6 months (search + notice) | 2 - 4 weeks (onboarding) | 1 - 2 weeks |
| Accountability | Revenue outcomes | Revenue outcomes | Activity metrics (impressions, clicks) | Deliverables (reports, slides) |
| Commitment | Month-to-month | Permanent hire (severance risk) | 6 - 12 month contracts | Project-based |
| Industry Depth | Multi-industry operator experience | Typically 1 - 2 industries | Varies, often generalist | Narrow specialization |
| Result Timeline | 30 - 60 days first results | 3 - 6 months to productivity | 60 - 90 days to pipeline impact | Report delivered, implementation separate |
What Clients Say About Working With MarkCMO
Results across CMO, COO, and advisory engagements. Measured in pipeline built, operations scaled, and revenue compounded.
"We needed a CMO who could also think like a COO. Mark rebuilt our demand generation system and our operational infrastructure simultaneously. Pipeline went from inconsistent to $1.4M in qualified deals in a single quarter. The ops side saved us 18 hours a week in manual work. I've never worked with anyone who could operate at that level in both domains."
"The diagnostic alone was worth more than our last agency engagement. Within two weeks I had a clear picture of exactly what was broken and why -- the ICP was wrong, the attribution model was a fiction, and we were spending 65% of our budget on channels that generated zero pipeline. That clarity changed everything that happened next."
"We were preparing for a Series B with no CMO and an investor asking hard questions about marketing scalability. Mark came in, built the GTM architecture, activated the demand engine, and produced the investor narrative that got us to the close. We raised $14M. The fractional model gave us a world-class CMO for the 90 days we actually needed one."
