The work

Growth stalls for a reason nobody names.

I did not set out to become a fractional CMO. I set out to answer a question: why do some companies with strong products scale aggressively, while others with equal potential stall? Over 25 years inside startups, Google, and AT&T, I watched the same pattern repeat. Founders build something real. Customers respond. Investors lean in. Then growth gets harder than it should. Not because the product weakens. Because the company has outgrown its story.

I call this narrative debtNarrative debtFounder-led storypaid40-person sales teamowedSeries B narrativeowedBalancecompounding: the compounding cost a company pays when its messaging outgrows its original clarity. It sits on a balance sheet no one keeps. Clearing it is the work I do, at the inflection point where traction is real but structure is missing. More about me.

The book

Nobody Knows What You Do by Jeff Lerner, hardcover edition

The moment your clarity stops transmitting.

Nobody Knows What You Do names the quiet problem I have watched play out inside companies at every stage of growth: the moment a company's internal clarity about what it does stops reaching the market. It distills 25 years of pattern recognition into the frameworks I use with founders today, launching September 22, 2026.

Also by Jeff: The Power of Relationships, a companion read on how careers and brands compound through authentic connection and earned trust.

Writing

Positions I am willing to be quoted on.

Speaking

One sharp claim per talk.

Marketing is not decoration. It is infrastructure. I speak to founder and investor audiences on category design, narrative debt, and when the fractional CMO model fits. Intros run under 100 words and every talk leaves the room with a framework they can use Monday morning. Invite Jeff to speak.

Off the clock

San Diego, baseball, dogs.

I have coached youth baseball at the La Costa Youth Organization for more than seven years and serve on its board of directors. I sit on the PTA board at my kids' elementary school, and every week I volunteer at the Rancho Coastal Humane Society. Baseball, school boards, and dogs have taught me more about organizational communication than most boardrooms have.
