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.
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 Boston team, selecting tooling, and writing the playbooks that keep results compounding.
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.
You are ready when the problem is clearly leadership rather than labor. Growth has stalled, the budget is a black box, the team has no strategist above it, or a fundraise is forcing the question. When a Boston company recognizes one of these, a fractional CMO delivers the ownership it is missing — fast.
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 gives you dedicated leadership but costs $250,000 or more all-in, takes months to hire, and is a heavy bet for a company still finding its stride. An agency gives you execution capacity but runs tactics against your brief — it does not own your strategy or answer for your revenue. A fractional CMO sits between: the ownership of an executive, part-time, at a fraction of the cost, scalable when your Boston business is ready.
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 Boston company would otherwise have to hire full-time.
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 Boston companies get real accountability, not advice from the sidelines. When the engagement winds down, the systems and the team remain.
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.
