Yes — managing existing agencies is one of the more common parts of the role. A fractional CMO sets the brief and success metrics for each agency, reviews their output against strategy, and holds them accountable, which is often more valuable than adding another agency on top.
This is also where a lot of value gets recovered fast: many companies are already paying agencies but have no one internally checking whether the work is actually driving the right numbers — a gap Kando's fractional CMO engagements are specifically designed to close.
