TL;DR

A marketing agency sells execution on specific channels with a team of junior specialists. A fractional CMO sells strategic leadership across all channels with one senior operator. The agency gives you hands. The fractional CMO gives you a brain. Most post-PMF companies need both, but the brain comes first.

  • Depth: Agency goes deep on 1-2 channels. Fractional CMO orchestrates all channels.

Frequently Asked Questions

Can I use both at the same time?

Yes, and many companies do. The fractional CMO sets strategy and manages the agency. This is often the best setup: senior leadership directing specialist execution.

When is an agency the better choice?

When you need pure execution on a single channel and already have strategic direction. If you know exactly what to do and just need hands, an agency is more cost-effective.
