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.
That is exactly the gap a fractional CMO fills. Instead of a $250k full-time bet, you bring in an experienced operator part-time to own strategy, run the team, and answer for pipeline — scaling their time up or down as the business needs. For most Boston companies it is the lowest-risk way to get real marketing leadership fast.
A fractional CMO takes the whole function off your plate. Positioning and messaging get locked so your Boston 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.
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.
A few clear triggers tend to prompt the call. Growth has stalled despite steady spend. You have marketers or agencies working hard with no senior strategy connecting them. Investors want to see a real growth engine before they fund. Or you simply refuse to gamble six months and a full salary on an unproven hire. For Boston companies, any of these is the moment.
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 pricing stays predictable and honest — a flat monthly retainer, no equity, no surprises, scaled to the leadership you need. It typically runs 30–50% of a full-time CMO’s total compensation, so most Boston, Massachusetts companies get the same quality of marketing ownership for meaningfully less than a full-time hire.
Brennen works like a founder who happens to run marketing. For your Boston company that means real ownership of strategy and results, hands-on execution instead of hand-offs, and a team and system built to keep compounding long after the engagement ends.
The best marketing hire we made was not full-time. Brennen owned the strategy and the number from day one.
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.
