Fractional CMO vs Marketing Agency
When to hire a fractional CMO, when to hire an agency, and when you need both. A direct comparison of cost, speed, depth, and outcomes.
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.
