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 is built for exactly this situation. You get executive-level marketing ownership — strategy, budget, hiring, and results — without the full-time salary or the six-month search. For a growing San Francisco, California business, it means senior leadership in weeks, not quarters, at a cost that fits your stage.
The role covers the whole function, not a slice of it. Brennen sets your positioning and message, builds the demand-generation engine that drives qualified pipeline for your San Francisco business, stands up analytics so you know what is working, and assembles the team and SOPs that keep it all running without him in the room every day.
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.
The signals are rarely subtle. Revenue is real but growth has flattened. Spend is up but attribution is murky. A capable team is busy but rudderless. A fundraise is looming and the growth engine is not investor-ready. Each of these, on its own, is enough reason for a San Francisco business to bring in fractional marketing leadership.
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.
A full-time CMO owns your marketing but costs like it — $250,000-plus and a hire you cannot afford to botch. An agency will execute all day but will never set your strategy or take your number. A fractional CMO gives a San Francisco company the missing middle: real ownership and senior judgment, part-time, at a price that fits.
Wondering how much a fractional CMO costs? Everything runs on a transparent monthly retainer. You are not giving up equity or signing a long contract, and the invoice does not move around. The retainer is set to your scope and, as a rule of thumb, comes in around 30–50% of full-time CMO comp — senior leadership most San Francisco companies find pays for itself in pipeline.
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 gave us the marketing leadership of a full-time CMO at a fraction of the cost and none of the risk.
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.
