Most San Francisco founders do not need more marketing hands — they need a marketing brain that owns the outcome. Without one, strategy, execution, and reporting all fall to people who were never meant to set direction. Hiring a full-time CMO solves it in theory, but the salary and the search make it a high-stakes gamble.
A fractional CMO gives you the leadership without the overhead. An experienced operator plugs into your San Francisco business, owns the marketing plan end to end, and stays accountable for results — while you keep the flexibility to scale the engagement as you grow. It is senior marketing ownership, sized to where you actually are.
Fractional CMO work spans strategy through execution. It begins with sharp positioning and messaging for your San Francisco, California audience, extends into demand generation tied to revenue, includes the analytics to prove what works, and finishes with team building — the right hires, the right stack, and the documented processes that outlast any one person.
A clear go-to-market for the San Francisco 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 Francisco, 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 Francisco 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 Francisco, California business the strategic ownership and revenue accountability of an executive — part-time, flexible, and a fraction of the price — bridging the two cleanly.
A fractional CMO engagement is a flat monthly retainer, sized to scope and free of equity or long contracts. Companies needing mostly strategy engage fewer days; those needing execution engage more. In practice fractional CMO rates run about 30–50% of full-time CMO comp, giving San Francisco businesses senior leadership at a fraction of the full-time price.
Brennen has run marketing from the operator’s seat, owning outcomes rather than opinions. For a San Francisco company that means senior judgment applied hands-on, a team and system left behind that keep producing, and a leader who treats your number as his own — not a consultant chasing the next deck.
Brennen operates like a founder — he owned the number, built the team, and the pipeline followed.
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 Francisco, 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 Francisco 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 Francisco 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 Francisco 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 Francisco, 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 Francisco, 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.
