Why growing San Diego businesses bring in a fractional CMO

The moment a San Diego 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.

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 Diego companies, it is the fastest way to put senior marketing leadership in the building.

What a fractional CMO actually does

As your fractional CMO, Brennen owns strategy, execution, and everything between. He sets positioning for the San Diego market, builds the channels that drive pipeline, installs the reporting that keeps everyone honest, and hires and manages the team and systems — so the marketing function runs whether or not he is on the call.

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.

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.

When San Diego companies bring in a fractional CMO

The triggers are consistent across San Diego companies: a growth plateau nobody owns, marketing spend with no clear return, a busy-but-directionless team, or a raise that needs a real growth narrative. Hit any of them and it is time to stop adding tactics and start adding leadership.

Fractional CMO vs. full-time CMO vs. agency

Each option trades off differently. A full-time CMO delivers dedication but demands $250k-plus and months of hiring risk. An agency delivers capacity but owns none of your strategy or results. A fractional CMO delivers what most San Diego companies actually need — senior ownership and accountability — part-time and at a fraction of the full-time cost.

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.

Why work with Brennen Lesser

Brennen leads marketing the way an owner would, because he has been one. He sets the strategy, builds the team, and stays on the hook for results — so San Diego companies get real accountability, not advice from the sidelines. When the engagement winds down, the systems and the team remain.

Brennen gave us the marketing leadership of a full-time CMO at a fraction of the cost and none of the risk.

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.
