CEO and CMO both lead, but they are looking at different things. Here is the split as I have lived it.
The CEO owns the whole business
Direction, money, operations, the big bets. When a marketing ask lands on their desk, they weigh it against everything else pulling at the same dollars, finance, ops, product.
The CMO owns how value gets sold
I bring the CEO ideas: new channels or campaigns, what they cost, what they should return. The CEO decides against the rest of the business. My job is to make the case in their language.
Where it breaks and where it works
Marketing dies when the CMO can only talk in marketing terms. It works when the CMO can translate everything into money and priorities the CEO can act on.
If you want that senior marketing thinking without a full-time hire, that is exactly what I do as a fractional CMO. If you would rather just talk it through, book a quick call.
