Results
The Challenge
The challenge
Sublue sells premium underwater scooters, a category with a high education burden, a strong seasonal window, and different buying behavior across the US and European markets.
- High product education burden. Generic ads could not explain use cases, safety, and premium value quickly enough.
- Market fragmentation. The US had scale but high education cost, while Europe required language, currency, logistics, and local channel adaptation.
- Product-line complexity. Flagship, mainstream, and entry products had different price points and audience profiles, so broad budget allocation created internal waste.
- Short seasonal window. Audience pools, creative libraries, and budget pacing had to be ready before the summer demand spike.
Our Solution
Our solution
Global Gravity rebuilt the operating cadence across creative production, paid media, localized content, and performance diagnostics.
- US and Europe operating model. The US program focused on high-intent audience pools and platform signal quality; European campaigns were split by market tier, language cluster, currency, and media mix.
- AI-assisted creative production. AI tools and designers worked in one review loop, increasing localized asset throughput while protecting product accuracy and premium brand cues.
- Native-language content system. Four-language copy was reviewed by local editors and AI checks, supported by a brand terminology library.
- Seasonal data cadence. The team managed pre-season warming, peak scaling, and closing-stage efficiency with different KPI and budget priorities.
Reusable growth assets
The work created a reusable market-entry framework, AI creative production workflow, and cross-platform diagnostic loop for later product launches and additional markets.
