Case Study: Remerge achieves reliable, high-performance, cost-effective infrastructure for massive in-app retargeting with Leaseweb

Remerge - Customer Case Study

Remerge is a Berlin-based AdTech company that provides app-to-app retargeting, helping clients reach and re-engage users with personalized in-app ads. Facing reliability problems with their previous host, Remerge needed infrastructure that could handle enormous scale—about 6 trillion bid requests per month and peaks of ~3 million requests per second—with sub-100ms response times and strict SLAs, because any downtime or slow response directly costs revenue.

Remerge moved 95% of its infrastructure to Leaseweb for lower costs, hardware customization and high-bandwidth bare-metal performance, deploying multi high-performance servers across Germany, the Netherlands, Singapore and the US. The migration delivered predictable, highly available performance, reduced bandwidth costs, and the scalability and support Remerge needs to meet SLAs and continue growing, giving them a clear competitive advantage.
