Founder of RealLoad

RealLoad is a next-generation enterprise tool for Stress Testing, Regression Testing, Synthetic Monitoring, and System Monitoring — all under one roof. Specifically engineered for monitoring and testing Web Sites and Web Services. It combines the sophisticated features of industry-leading tools with innovative, unique capabilities found nowhere else.

RealLoad has been built from the ground up with a focus on scalability, security and ease of use. Using RealLoad is significantly more cost-effective than competitors who only offer point solutions - and also much more cost-effective and powerful than developing solutions in-house.

The RealLoad Portal is hosted in Switzerland. The staff speaks English, German and Swedish.
