What does a fractional CMO actually do?

What the role covers

Setting the strategy and the budget allocation across channels. Deciding what gets done and what deliberately does not. Hiring and managing agencies, contractors, and junior marketers. Reporting to the founders or the board on what the money produced.

The work is mostly judgement and prioritisation rather than execution. If you need someone to build the campaigns, that is a different hire.

How it differs from a consultant

A consultant diagnoses and recommends. A fractional CMO carries the outcome. That changes the relationship: they are in your planning meetings, they are accountable for the forecast, and they are reachable when something breaks on a Tuesday.

It also differs from an agency, which owns the channels it is paid to run but not the decision about whether those are the right channels.

Who it suits

Companies with enough marketing spend that the allocation decision matters, and not enough to justify a full-time executive salary. In practice that often means a business with marketing activity running but nobody senior deciding whether it adds up.

If nobody in your company can currently answer what your marketing produced last quarter, that is the symptom this role exists to fix.

What it is not

It is not a cheap way to get campaigns built. A fractional CMO spending their day in your ad account is an expensive media buyer. The value is in the decisions above the execution, so it only pays off if there is execution capacity underneath.
