Fractional CMO vs Marketing Agency

Respuesta rápida

A fractional CMO is a senior marketing executive who joins your team part-time to provide strategic leadership — owning your marketing direction, managing vendors, and aligning marketing to business goals. A marketing agency executes specific campaigns or channels. The core difference: a fractional CMO provides strategy and leadership; an agency provides execution.

¿Cuál deberías elegir?

Most growing companies need both — a fractional CMO for strategic leadership and agencies for channel execution. If you are spending on agencies without clear strategy, hire a fractional CMO first: they will determine which agencies to use, at what budgets, with what KPIs. Without strategic leadership, agency spend is often poorly allocated.
