Ambitious Chicago businesses often find themselves with marketing that is busy but not accountable. Campaigns ship, agencies invoice, and growth still stalls because no senior operator owns the plan. The traditional answer, a full-time CMO, is a $250,000 line item and a months-long recruit — a lot to commit before you know it will work.
A fractional CMO closes that gap. You get a seasoned marketing executive embedded in your business part-time — owning the strategy, building and leading the team, and taking accountability for the number — for a fraction of the cost of a full-time hire and with none of the hiring risk. For most Chicago companies, it is the fastest way to put senior marketing leadership in the building.
The job is to own marketing the way a full-time CMO would. That is strategy and positioning for your Chicago market, a demand engine that produces qualified pipeline, attribution that ties spend to revenue, and the hiring and process work that leaves you with a functioning department, not a dependency.
A clear go-to-market for the Chicago 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 Chicago company to start fractionally.
Weeks 1–2: understand your funnel, goals, data, and the gaps holding Chicago 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.
Weigh the three options and the fractional model stands out. A full-time CMO means dedicated leadership at $250k-plus and a months-long hire. An agency means hands, not ownership — it executes your brief and bills you for it. A fractional CMO gives you the strategic accountability of an executive, delivered part-time and priced for your Chicago stage.
Fractional CMO billing could not be simpler: a set monthly retainer scoped to the work, no equity, no long-term contract, no hidden fees. It generally lands at roughly a third to a half of what a full-time CMO would cost all-in — which is why most Chicago companies view it as leadership that pays for itself rather than an added expense.
What Chicago 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.
Brennen ran our marketing like an owner. He set the strategy, built the team, and the pipeline came.
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 Chicago, Illinois 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 Chicago 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 Chicago 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 Chicago 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 Chicago, Illinois 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 Chicago, Illinois 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.
