Case Study: Swappie improves ROAS by 15% with Supermetrics

How Swappie used marketing mix modeling powered by Supermetrics and Google Cloud to improve ROAS by 15%

Swappie, a leading refurbished phone marketplace, needed a better way to measure the impact of its marketing spend in a privacy-first environment. The company had been using Funnel as its data pipeline provider, but was looking for improved pricing, a better developer experience, and a stronger foundation for future marketing data use cases, including marketing mix modeling (MMM).

Swappie switched to Supermetrics to automate marketing data collection into BigQuery and support its MMM workflow with Google Cloud and Vertex AI. By using Supermetrics-powered MMM to simulate channel performance, diminishing returns, and budget scenarios, Swappie optimized spend allocation and improved ROAS by 15%, while also gaining a clearer, more objective view of marketing efficiency.
