Scaling DTC acquisition 4× without raising CAC

+312% ROAS

The challenge

Northwind was scaling spend but watching CAC climb in lockstep. Growth was real but unprofitable, and the team couldn't tell which channels actually drove incremental revenue.

Our approach

We rebuilt attribution from the ground up, layered a predictive audience model over their first-party data, and handed bidding to an automated system that optimised toward margin, not clicks.

The outcome

Acquisition volume quadrupled while blended CAC held flat. The growth system we left behind keeps compounding without added headcount.
