For a fast-growing Boston, Massachusetts company, the marketing gap is rarely effort — it is leadership. Plenty of activity, plenty of spend, but no one connecting it to revenue. A full-time CMO would close that gap, yet the cost and the hiring timeline make that a heavy bet at your stage.
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.
Fractional CMO leadership means one accountable owner for the entire function: positioning that makes your Boston, Massachusetts value obvious, demand generation measured to revenue instead of clicks, attribution you can trust, and a team plus a set of SOPs that keep the engine running long after the strategy is set.
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.
Bringing in a fractional CMO makes sense the moment marketing needs a decision-maker, not more doers. That is often when a Boston, Massachusetts company plateaus, when spend gets hard to justify, when a team lacks direction, or when investors start asking how growth actually works. Any one of these is your cue.
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.
Think of it as a spectrum. On one end, a full-time CMO: total commitment, total cost, slow to hire. On the other, an agency: plenty of output, no strategic ownership. In the middle sits the fractional CMO — the judgment and accountability of a senior executive without the salary or the six-month search, sized to your Boston, Massachusetts business.
How much does a fractional CMO cost? Engagements are billed as a flat monthly retainer — no equity, no long-term lock-in, and no surprise invoices. The retainer is scoped to how much leadership you need, and as a rule of thumb runs about 30–50% of what a full-time CMO would cost in total compensation. For most Boston, Massachusetts companies that means senior marketing leadership that pays for itself in pipeline.
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.
He plugged in like a founder, took the number as his own, and turned our marketing into a real engine.
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.
