A logo designer. A social media person. Someone for the website. Someone else for ads. Each one good at their one thing, and none of them talking to each other.
The owner ends up doing the job nobody was hired for: holding the whole picture together, chasing updates, explaining the same context five times.
A growth partner replaces the pile with one plan. One person who sees the market, the website, the content and the follow-up as one system, not five separate invoices.
That is the real value. Not doing more things. Doing them as one thing.
