The moment a San Diego business gets serious about growth, the absence of marketing leadership becomes expensive. Money goes out, activity happens, and results are impossible to attribute. A full-time CMO could take the wheel, but the total comp and the long recruiting cycle put that out of reach for a lot of otherwise-ready companies.
The fractional model solves both problems at once. You bring in an executive-caliber marketing leader part-time — owning strategy, managing the team, and reporting to revenue — for roughly a third to a half of a full-time CMO. For most San Diego companies, senior leadership stops being a someday hire and becomes something you have now.
As a fractional CMO, the mandate is total marketing ownership. That means nailing positioning for the San Diego market, building channels and campaigns that generate real pipeline, wiring up attribution so nothing is guessed at, and hiring and directing the marketers, tools, and processes that make the function self-sustaining.
A clear go-to-market for the San Diego market and beyond — messaging your whole team can repeat.
Channels and campaigns that produce pipeline, measured to revenue instead of clicks.
The right hires, tools, and SOPs — a marketing department that runs itself.
Honest reporting that ties every dollar of spend back to pipeline and closed revenue.
A marketing budget allocated by someone accountable for the return on it.
Marketing that sales trusts and the board understands — one shared number.
Bringing in a fractional CMO makes sense the moment marketing needs a decision-maker, not more doers. That is often when a San Diego, California company plateaus, when spend gets hard to justify, when a team lacks direction, or when investors start asking how growth actually works. Any one of these is your cue.
Weeks 1–2: understand your funnel, goals, data, and the gaps holding San Diego growth back — talk to sales, customers, and the numbers.
Weeks 2–4: lock positioning, choose the channels that fit your motion, and build a 90-day roadmap tied to revenue targets.
Weeks 4–8: install the systems, make or manage the hires, launch the channels, and start producing measurable pipeline.
Weeks 8–12 and on: attribution to revenue, cut what is not working, and double down on what is — then keep compounding.
The full-time CMO gives dedication but at $250k and months of risk. The agency gives output but owns nothing above the task list. The fractional CMO gives your San Diego, California business the strategic ownership and revenue accountability of an executive — part-time, flexible, and a fraction of the price — bridging the two cleanly.
The fractional CMO cost is a predictable monthly retainer, nothing more. No equity handed over, no multi-year lock-in, no line items you did not expect. The number tracks the work and typically runs 30–50% of full-time CMO compensation — meaning most San Diego companies get senior marketing leadership for well under the cost of hiring one.
The difference with Brennen is ownership. He does not parachute in with recommendations and leave; he embeds in your San Diego, California business, builds the engine, leads the people, and answers for pipeline. You end the engagement with a marketing function that stands on its own.
He did not hand us a deck and leave. He built the system, hired the people, and stayed on the hook for results.
Client, B2B SaaS — CEO
A fractional CMO is an experienced chief marketing officer who leads your marketing on a part-time, ongoing basis instead of as a full-time employee. You get executive-level strategy, team leadership, and accountability for growth — at a fraction of the cost of a full-time hire, and without the long recruiting cycle or equity package.
Yes. Brennen Lesser works with San Diego, California companies as a fractional CMO — both remotely and on-site as the engagement requires. That includes founder-led startups, funded scale-ups, SaaS businesses, professional-services firms, and established B2B companies across the San Diego metro.
Most fractional CMO engagements run at roughly 30–50% of a full-time CMO salary, billed as a flat monthly retainer with no equity and no long-term contract. The exact number depends on scope and how many days a month you need. For most San Diego companies that is a meaningful saving versus a full-time executive who would command $250,000 or more in total compensation.
An agency executes tactics — ads, content, email — usually against a brief you provide. A fractional CMO sits a level above that: they set the strategy, decide which channels to invest in, hire and manage the people (or agencies) who execute, and own the results. Think of it as renting a marketing leader, not renting a marketing vendor.
If you have the budget, the workload, and the revenue to support a $250k+ executive full-time, hire one. If you need senior marketing leadership now but can’t yet justify that cost — or you want to de-risk the decision before committing — a fractional CMO gives you the same caliber of leadership scaled to your stage, and can help you hire your eventual full-time CMO when the time comes.
Most San Diego engagements ramp in about two weeks. You skip the four-to-six-month executive search entirely — after a short discovery period, Brennen is embedded in your business, auditing the funnel and shipping a strategy while a full-time search would still be scheduling first-round interviews.
Typically seed-to-Series-B startups, SaaS companies, and growing B2B firms in San Diego, California doing roughly $1M–$50M in revenue — companies large enough to need real marketing leadership but not yet large enough to justify a full-time CMO on payroll.
Clear positioning your whole team can articulate, a demand-generation engine measured to pipeline and revenue, honest attribution so you stop wasting spend, and a marketing team and set of systems that keep producing after the engagement scales down. The goal is a self-sustaining function, not dependence on a consultant.
Both. Brennen works with San Diego, California teams remotely day-to-day and comes on-site for kickoffs, planning sessions, and key moments where being in the room matters. Modern marketing leadership doesn’t require a desk in your office five days a week.
