The moment a Boston 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.
The fractional model solves both problems at once. You bring in an executive-caliber marketing leader part-time — owning strategy, managing the team, and reporting to revenue — for roughly a third to a half of a full-time CMO. For most Boston companies, senior leadership stops being a someday hire and becomes something you have now.
A fractional CMO owns marketing end to end. First comes positioning: who you serve, what makes you different, and why Boston buyers pick you. Then demand generation — the channels and campaigns that produce pipeline measured to revenue — followed by honest attribution and the hiring, tooling, and process work that turns marketing into a system rather than a scramble.
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.
It tends to come down to a handful of triggers. You have hit a growth ceiling and no one owns breaking through it. You are spending without clear attribution. You have people executing with no strategy above them. Or you are gearing up to raise. For a Boston company facing any of these, fractional leadership is the practical next move.
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.
The full-time CMO gives dedication but at $250k and months of risk. The agency gives output but owns nothing above the task list. The fractional CMO gives your Boston, Massachusetts business the strategic ownership and revenue accountability of an executive — part-time, flexible, and a fraction of the price — bridging the two cleanly.
A fractional CMO is priced as a flat retainer, billed monthly, with no equity and no lock-in. The fractional CMO cost depends on how many days of leadership you need and typically works out to 30–50% of a full-time CMO’s total compensation. For Boston, Massachusetts companies, it is executive marketing without the executive-sized payroll.
What Boston businesses get with Brennen is an operator, not an advisor. He has built demand engines and hired teams from the inside, and he brings that same ownership to your marketing — in the pipeline reviews, in the hiring calls, and answerable for the number the whole way through.
Within a quarter Brennen had our positioning, pipeline, and team pointed in one direction — and it showed.
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.
