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 closes that gap. You get a seasoned marketing executive embedded in your business part-time — owning the strategy, building and leading the team, and taking accountability for the number — for a fraction of the cost of a full-time hire and with none of the hiring risk. For most San Francisco companies, it is the fastest way to put senior marketing leadership in the building.
A fractional CMO owns marketing end to end. First comes positioning: who you serve, what makes you different, and why San Francisco buyers pick you. Then demand generation — the channels and campaigns that produce pipeline measured to revenue — followed by honest attribution and the hiring, tooling, and process work that turns marketing into a system rather than a scramble.
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 timing is usually obvious once you see the signals. You have product-market fit and revenue, but growth has plateaued and no one owns the plan to restart it. You are spending on marketing and cannot say what drives pipeline. You are preparing to raise and need a credible growth engine. Any one of these is a good reason for a San Francisco company to start fractionally.
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 gives you dedicated leadership but costs $250,000 or more all-in, takes months to hire, and is a heavy bet for a company still finding its stride. An agency gives you execution capacity but runs tactics against your brief — it does not own your strategy or answer for your revenue. A fractional CMO sits between: the ownership of an executive, part-time, at a fraction of the cost, scalable when your San Francisco business is ready.
Fractional CMO billing could not be simpler: a set monthly retainer scoped to the work, no equity, no long-term contract, no hidden fees. It generally lands at roughly a third to a half of what a full-time CMO would cost all-in — which is why most San Francisco companies view it as leadership that pays for itself rather than an added expense.
Brennen is a builder first. He has stood up marketing teams and demand systems from scratch, and he brings that to San Francisco companies as a fractional CMO — hands in the work, accountable for results, and focused on leaving behind a machine that runs without him.
The best marketing hire we made was not full-time. Brennen owned the strategy and the number from day one.
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.
