What a fractional CMO does for a San Diego business that agencies cannot

Growth-stage San Diego 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 bridges the gap cleanly. You get a senior marketing operator running your strategy and team on a retainer — accountable for pipeline, flexible on hours, and free of the risk and cost of a full-time hire. For San Diego businesses, it is often the difference between marketing that drifts and marketing that compounds.

What a fractional CMO actually does

A fractional CMO takes the whole function off your plate. Positioning and messaging get locked so your San Diego buyers understand why you win; demand generation gets built and measured to pipeline; analytics get honest; and the team, tools, and SOPs get put in place so marketing keeps producing when the engagement scales down.

What you get

01

Strategy & positioning

A clear go-to-market for the San Diego market and beyond — messaging your whole team can repeat.

02

Demand generation

Channels and campaigns that produce pipeline, measured to revenue instead of clicks.

03

Team & operations

The right hires, tools, and SOPs — a marketing department that runs itself.

04

Analytics & attribution

Honest reporting that ties every dollar of spend back to pipeline and closed revenue.

05

Budget ownership

A marketing budget allocated by someone accountable for the return on it.

06

Executive alignment

Marketing that sales trusts and the board understands — one shared number.

How San Diego companies know it is time for a fractional CMO

The right time is usually when effort stops translating into growth. Your San Diego team is working, the invoices are getting paid, and the numbers still are not moving — because no senior operator owns the plan. Add an approaching raise or an undefendable budget, and the case for a fractional CMO makes itself.

02

Strategy & plan

Weeks 2–4: lock positioning, choose the channels that fit your motion, and build a 90-day roadmap tied to revenue targets.

Weeks 8–12 and on: attribution to revenue, cut what is not working, and double down on what is — then keep compounding.

Fractional CMO vs. full-time CMO vs. agency

The comparison is simple once you frame it. Full-time CMO: maximum leadership, maximum cost, slowest to onboard. Agency: maximum execution, minimal ownership. Fractional CMO: executive-level strategy and accountability on a part-time retainer, with the flexibility to scale up or transition to full-time when your San Diego business is ready.

How pricing works

Fractional CMO fees are straightforward: one flat monthly retainer, no equity, no long-term commitment, no surprises. It is scoped to how much leadership the business needs and usually falls between 30% and 50% of a full-time CMO salary — a fraction of the cost for the same caliber of ownership a San Diego company would otherwise have to hire full-time.

Frequently asked questions

What is a fractional CMO?

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.

Do you offer fractional CMO services for San Diego companies?

Yes. Brennen Lesser works with San Diego, 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 Diego metro.

How much does a fractional CMO cost in San Diego?

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 Diego companies that is a meaningful saving versus a full-time executive who would command $250,000 or more in total compensation.

How is a fractional CMO different from a San Diego marketing agency?

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.

Fractional CMO vs. full-time CMO — which does my San Diego company need?

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.

How quickly can we start?

Most San Diego 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.

What size San Diego company is this right for?

Typically seed-to-Series-B startups, SaaS companies, and growing B2B firms in San Diego, 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.

What results should we expect?

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.

Do you work on-site in San Diego or remotely?

Both. Brennen works with San Diego, 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.
