At some point, most Boston businesses realize their marketing has no one truly steering it. Freelancers execute in silos, an agency runs campaigns against a brief, and no single person owns whether any of it produces pipeline. The obvious fix — a full-time CMO — costs a quarter of a million dollars and months of hiring risk.
A fractional CMO gives you the leadership without the overhead. An experienced operator plugs into your Boston 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.
As your fractional CMO, Brennen Lesser takes ownership of the entire marketing function. It starts with positioning and messaging — getting clear on who you serve and why Boston buyers should choose you. From there it moves into demand generation, analytics and attribution, and building the team: hiring the right marketers, choosing the right tools, and writing the SOPs that keep the machine running.
A clear go-to-market for the Boston 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 Boston company to start fractionally.
Weeks 1–2: understand your funnel, goals, data, and the gaps holding Boston 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.
A full-time CMO owns your marketing but costs like it — $250,000-plus and a hire you cannot afford to botch. An agency will execute all day but will never set your strategy or take your number. A fractional CMO gives a Boston company the missing middle: real ownership and senior judgment, part-time, at a price that fits.
The fractional CMO cost is a predictable monthly retainer, nothing more. No equity handed over, no multi-year lock-in, no line items you did not expect. The number tracks the work and typically runs 30–50% of full-time CMO compensation — meaning most Boston companies get senior marketing leadership for well under the cost of hiring one.
The difference with Brennen is ownership. He does not parachute in with recommendations and leave; he embeds in your Boston, Massachusetts business, builds the engine, leads the people, and answers for pipeline. You end the engagement with a marketing function that stands on its own.
Brennen left us with a marketing function that runs itself. That is the whole point, and he delivered it.
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 Boston, Massachusetts 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 Boston 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 Boston 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 Boston 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 Boston, Massachusetts 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 Boston, Massachusetts 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.
