All agencies

Fractional CMO & strategy agencies, reviewed and ranked

Senior marketing leadership on part-time terms. Scored on whether they diagnose and make tradeoffs, or arrive with a playbook from their last company.

14 evaluated, of which we would put 12 in front of a client and cut 2.

You are buying judgement, so test the diagnosis

The heaviest dimension here is whether they can diagnose market, customer, positioning, funnel, economics and organisational constraints — then make explicit tradeoffs about what not to do. The tell is in the first conversation: an operator asks uncomfortable questions about your economics; a vendor presents a framework.

Ask what they have actually run, at what stage

Pattern recognition is stage-specific and category-specific. Someone who scaled a $50M brand has genuinely little to offer a pre-product-market-fit company, and the reverse is equally true. Named former CMO or equivalent operator experience at your stage is what this rubric rewards, not seniority in the abstract.

The output should include a team that can continue

Good fractional leadership leaves durable capability behind — hires made, processes established, people who can run it after. If the engagement's value evaporates the day it ends, you rented a consultant rather than building a function.

Fractional CMO

Cut · Fractional CMO / Strategy · scored 2.68/5

A transparent strategy membership sold under the fractional-CMO label, but one monthly 1:1 and group calls do not equal embedded executive ownership.

CMOx

Cut · Fractional CMO / Strategy · scored 1.86/5

A training and coaching business for people launching fractional CMO practices; its visible reviews do not validate client-side CMO delivery.

How this page is built: every vendor here is scored against the published fractional_cmo rubric — the one written for what this category actually sells, not a general agency rubric. Several of these records were first filed elsewhere and scored against a rubric they were not competing in; where that happened, the record carries a rescored_from field showing the previous verdict and score, so the change is auditable rather than silent.
