The moment a San Francisco 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.
That is exactly the gap a fractional CMO fills. Instead of a $250k full-time bet, you bring in an experienced operator part-time to own strategy, run the team, and answer for pipeline — scaling their time up or down as the business needs. For most San Francisco companies it is the lowest-risk way to get real marketing leadership fast.
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 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.
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.
Fractional CMO pricing is a simple flat monthly retainer with no equity and no long contracts. It is sized to the scope — fewer days a month for strategy and oversight, more for hands-on building — and generally lands around 30–50% of a full-time CMO’s total comp. For a growing San Francisco business, that is executive leadership that earns its keep.
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 turned scattered marketing activity into an accountable growth engine we still run today.
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.
