Growth-stage San Francisco companies frequently have the pieces of a marketing function — a few marketers, some agencies, a budget — but no one holding them together or on the hook for pipeline. Bringing in a full-time CMO would fix the ownership problem while creating a cost and timing problem most teams are not ready for.
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.
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.
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.
Think of it as a spectrum. On one end, a full-time CMO: total commitment, total cost, slow to hire. On the other, an agency: plenty of output, no strategic ownership. In the middle sits the fractional CMO — the judgment and accountability of a senior executive without the salary or the six-month search, sized to your San Francisco, California business.
A fractional CMO is priced as a flat retainer, billed monthly, with no equity and no lock-in. The fractional CMO cost depends on how many days of leadership you need and typically works out to 30–50% of a full-time CMO’s total compensation. For San Francisco, California companies, it is executive marketing without the executive-sized payroll.
Brennen is an operator who has built and led marketing teams from the inside — owning the number, not just advising on it. San Francisco companies get senior judgment, hands-on execution, and a system the team keeps running after the engagement scales down. He works like a member of your leadership team, not a consultant who hands you a deck and disappears.
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.
