*Core concept* · *Fractional CMO*

## Definition

A fractional CMO is a senior marketing leader who works with a company on a part-time or project basis, providing CMO-level strategy without the cost or commitment of a full-time executive hire. Engagements typically run on a defined scope with a defined term.

## Why It Matters for AI Search

The [fractional CMO](https://www.platelunchcollective.com/services/consulting/fractional-cmo) model exists because most $2M–$20M businesses need senior marketing thinking but cannot justify — or fill — a full-time CMO role. The fractional model gives those businesses access to someone who has built marketing functions before, without the overhead. In the context of AI search, a fractional CMO with [AI SEO](https://www.platelunchcollective.com/services/ai-seo) fluency bridges the gap between the technical work of retrieval optimization and the strategic decisions about positioning, messaging, and channel priority that determine what gets optimized.

## Common Misconception

A fractional CMO is not a consultant who delivers a report. The engagement is executional — the fractional CMO makes decisions, manages vendors, and owns outcomes, not just recommendations.
