The two things this seat is actually for: a numerical investment thesis on every marketing spend, and category intelligence deep enough to see what the MVP in your category does that you don't.
What a fractional CMO should actually be capable of doing is presenting clients with a numerical investment thesis for any marketing channel investment, and supporting how that investment ties back to the brand and to company revenue goals. It has been said that it's hard to know what half of marketing is working. Well, before signing off on any one marketing investment, there should be a clear-eyed understanding of what that investment creates. A fractional CMO should also be capable of explaining how an investment needs to be layered into the totality of a funnel strategy. If you're an entirely new brand coming to market, you need a different messaging funnel than if you are Coca-Cola.
The fractional CMO should also put incredible emphasis on understanding who is doing what in the category. If you joined a major sports league, you would study what the MVP does to be a leader in the advanced analytical categories that matter. Your CMO should present a similar detailed breakdown. Odds are you're not creating a category. But even if you are, your fractional CMO should be able to draw parallels to other categories. You are not the first brand to ever try to create a category.
At Factor_, I owned acquisition and helped move the business from a $14M to $18M run rate in nine months. That's the level of numerate accountability the seat should carry. Not "we ran some campaigns." Actual dollars, actual growth, tied back to a plan I could defend on a whiteboard.
Before we sign off on any marketing investment, we produce a written thesis with the same four sections. Here is the template, applied to a common ask: "Should we invest $150K/mo in paid social?"
Concrete lead volume, pipeline dollars, and attributed revenue projections at 90 and 180 days. Not "we expect awareness lift." Instead: "at $150K/mo and our current LTV, this creates 480 MQLs, 96 SQLs, and $1.4M in attributed pipeline by day 180."
Every channel investment reallocates attention, budget, or team capacity from something else. The thesis names what: "this $150K comes from what would otherwise fund the SDR expansion. We're betting inbound quality beats outbound volume for this ICP."
When does the investment pay itself back and against what benchmark. "Payback at month 7 assuming current close rate and $28K ACV; if close rate drops below 22%, payback moves to month 11 and we re-evaluate."
What happens if the number misses. "If CPL runs 40%+ above target at day 45, we pull back to $75K/mo and redirect the remainder to a lifecycle motion." Kill switch clearly named before spend starts, not after.
Every investment in the plan gets this treatment. Fund reviews stop being arguments about opinion and start being conversations about the numbers behind each thesis.
In every engagement, we document four things about your category. Not a competitive matrix. Not feature checkboxes. The advanced-analytics view a real MVP-level operator would build.
Not "who is the market leader." Instead: which specific value promise does each top player anchor on, which buyer type do they own, and which promise are they NOT willing to make. The wedges are what actually determine whether your positioning has clear air or is fighting for the same territory.
What does the MVP measure and act on that the mid-tier players don't? For most B2B categories, this is buyer signal sophistication, funnel-conversion instrumentation, and account-based intent data. Naming this gap is what tells us whether the category leader is defensible or catchable.
If you woke up tomorrow as the CMO of your top competitor, what are the first three moves you'd make. This forces empathy at the operator level, not the analyst level. Half the time it reveals moves your own team hasn't considered.
You are not the first brand to try to create a category. Which prior category creation is yours most analogous to, and what did that operator do at your stage that worked. Marketo did it. Salesforce did it. HubSpot did it. Each left a playbook worth studying before you write your own.
The thesis and category work above become the foundation. From there, every engagement runs through Treetop's three-phase method: Memory (the customer and category data we reason over), Intelligence (the investment-thesis machinery), and Motion (the shipped work). Full walkthrough: the Revenue Engine Method.
Typical cadence: weekly working sessions with the CEO or founding team, biweekly deep-dive with the marketing operators (yours or ours), monthly board-facing dashboard walkthrough, and continuous work on the current investment thesis in a shared workspace. New to the model? What is a fractional CMO is the full primer; cost benchmarks live here; timing guidance here.
The Fractional CMO engagement is priced as a flat monthly retainer with a 90-day minimum. There is no public rate card, because the range from a light advisory relationship to a full interim CMO is too wide to price with one number. Every engagement is scoped on a 30-minute strategy call and quoted before you commit to anything.
Anchor: most engagements land between what the Embedded subscription costs and what a full-time CMO would cost. The retainer covers Bill's time, the tooling that runs the engine, and management of any doers on your team.
Three common options for B2B marketing leadership. Each has a place, but fractional CMO closes the gap between underpowered agency retainers and the cost and timeline of a full-time hire.
