Keep the roots. Refine everything around them.

The first month is measurement and diagnosis. Access, conversion tracking and attribution get repaired before spend moves, because changing budgets against numbers you do not trust is guessing. The second month is restructuring: the accounts, the audiences and the pages the traffic lands on, with the first tests live. The third month is when scaling decisions start, made on evidence gathered in the two months before rather than on a plan written before we saw anything.

It means the person who designs the strategy is the person who runs it day to day, and the person you call when something looks wrong. There is no account executive relaying your question to an analyst you have never met, and no junior team learning your business on your budget. It also caps how many accounts we take at once. That limit is the cost of the model, and the reason it works.

Attention versus leverage. A boutique gives you senior people and direct access, then hits a ceiling the moment a budget requires enterprise buying or research it cannot run in house. A holding company has that leverage and buries it under account layers and approval chains built for its own margins. The difference you feel day to day is not scale. It is who is actually doing the work on your account, and how many people sit between you and them.

When the seams start costing more than the specialisms are worth. Three signals: your channels report different numbers for the same week, nobody can tell you what your brand spend did to your search performance, and decisions wait for the next monthly cycle. Consolidate when coordination has become the bottleneck — not simply because you have more than one vendor. Plenty of programs run well across two or three partners when someone is genuinely accountable for the handoffs.
