Our story


The Key-Performance activity was launched in the year 2000 as a spin-off of UBIZEN (now Verizon) in partnership with Keynote Systems (now Dynatrace Synthetic) in the Benelux. It was the early days of end-to-end performance monitoring. This resulted in a strong relation with Keynote/Dynatrace and today Key-Performance is the oldest and largest Keynote/Dynatrace synthetic partner.


Key-Performance went on to develop knowledge in other technologies in the field of web performance. The following technologies were introduced on the Benelux market:

2002 Redline (first Front End Optimization)

2004 Adlex (now Dynatrace DC RUM)

2004 Load Testing services

2011 Dynatrace” became Dynatrace AppMon


Key-Performance became an independent company. Application Performance Management developed into the central activity of Key-Performance as a pioneer on this market.


The evolution of Key-Performance clients’ needs and the web performance optimization market drove us to partner and develop knowledge in innovative and complementary technologies:

2012 APM as a service (consulting)

2014 Mobile app performance with Apteligent

2016 Fasterize (Front End Optimization in SaaS model)


Merger of Keynote and Dynatrace. Key-Performance became a global partner of Dynatrace on the various web performance technologies: Synthetic monitoring, Real user monitoring, APM, etc.
