How did The Social Hub (B Corp™) cut experimentation costs by 82% while scaling their testing program? Rudger de Groot of mintminds AG recently shared his success with us in helping The Social Hub expand their experimentation program with GrowthBook. The challenge: As the program scaled, so did BigQuery costs. BigQuery costs for GA4 data were hitting $200–400/month. Even though GrowthBook's costs were affordable compared to other platforms, was there room to increase testing in the current budget? The solution: Mintminds with GA4Dataform by Superform Labs optimized The Social Hub's BigQuery setup by using flattened datasets instead of nested GA4 tables. The results: → 81.8% reduction in BigQuery processing costs → Query speeds improved from minutes to seconds → Total cost: $303/month (vs. $546 unoptimized) → Unlimited testing without budget constraints "This didn't just reduce GrowthBook costs—it optimized all our BigQuery reports and dashboards," says Laura Semeraro, Digital Analyst at The Social Hub. For dev and data teams tired of rationing experiments due to cost, this article shows a path to enterprise-grade experimentation at a fraction of the price. 📊 Full technical breakdown with A/A test methodology link below. #ABTesting #DataEngineering #GrowthBook #BigQuery #Experimentation
