Fractional CMO · vs Consultant

Fractional CMO vs Consultant

Consultants write decks. Fractional CMOs ship pipeline. IG's operating company thesis is the proof.

A consulting engagement and a fractional CMO engagement can cost roughly the same. They produce roughly the opposite output.

A consultant gives you a strategy deck and a recommendation. A fractional CMO operates inside the company until the recommendation is shipped.

When a consultant is the right call

You need an outside perspective on a defined strategic question. You have the internal team to execute. The consulting engagement ends with a deck the team will actually run.

McKinsey-style brand-positioning audits or Big Four AI-strategy decks fit this shape. Useful in their own right, structurally different from what a fractional CMO does.

When a fractional CMO is the right call

You need the strategy AND the operating capacity to ship it. The internal team can execute but does not have senior marketing leadership. The fractional CMO is the senior leader plus the operating accountability.

IG case studies are the proof: AllVoiceAI fractional CMO engagement shipped positioning, GTM, narrative, and investor-readiness inside the engagement window. OneBenefits shipped Marketing AI in eight weeks.

The structural difference

A consultant writes "the marketing plan should do X." A fractional CMO does X. The first model bills against the deck. The second model bills against the outcome.

IG's engagement model is built around outcome ownership. If the work does not ship, the engagement does not produce the result we both signed up for.
