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.
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.
Brennen runs the full marketing stack as your fractional CMO: positioning and narrative first, then the demand-generation systems that fill the pipeline, then attribution so spend is defensible — and throughout, building the San Francisco team, selecting tooling, and writing the playbooks that keep results compounding.
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.
Most San Francisco companies reach for a fractional CMO at a recognizable moment: growth stalls, marketing spend outpaces provable results, or a funding round exposes the lack of a real go-to-market plan. If any of that sounds like your business, the timing is right — and starting fractionally beats waiting on a full-time search.
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.
Weigh the three options and the fractional model stands out. A full-time CMO means dedicated leadership at $250k-plus and a months-long hire. An agency means hands, not ownership — it executes your brief and bills you for it. A fractional CMO gives you the strategic accountability of an executive, delivered part-time and priced for your San Francisco stage.
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 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.
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.
