The Challenge

FishSkyn faced four interconnected obstacles. Daily stress and decision fatigue from managing campaigns that consumed significant mental bandwidth. Performance volatility made scaling decisions unreliable. Limited product development bandwidth prevented launches of AirPods cases, wallets, and airbag cases. And without clear unit economics analysis, the path to optimal spend levels remained unclear. As founder Thomas put it: the unpredictable performance was a constant source of stress for the business.

The Solution

We deployed a four-pillar approach. Financial clarity first: full analysis of unit economics (MER, CAC, and contribution margins tracked daily). Creative development using our proprietary AdIQ tool to analyze creative elements linked to performance metrics, identifying top-performing headlines like 'Tough on Scratches, Sleek in Style' and 'Protection Without the Bulk.' UGC-style content and problem-solution storytelling drove higher engagement. A true partnership model where creative looked like it was designed in-house. And an integrated approach with in-house creative production ensuring brand consistency. Full trust was established by week four.
