It’s all about Performance

We help you to control and improve your web,
app and network performance

Speed impacts your business

One second speed improvement means 7% conversion rate; 5 to 11% pageviews increase.

We believe web performance is a must-have to have user-friendly websites and applications. It has a real impact on the user behavior. And it can be measured for each website, each page, each functionality.

I am managing an online business (e-commerce, media, e-banking,..)

  • Know which speed your users are experiencing: stop guessing, start knowing.

  • Allocate your website budget wisely: based on your real users visits, know the impact of each second of acceleration on your business metrics (e-commerce or ad revenue; conversion rate; session length, etc).

  • Follow the speed and improvements on your website without having to have a PhD in computer sciences.

  • Improve your website speed and your user retention: reduce your bounce rate; improve your sessions length and your conversion rate.

I am a development / infrastructure manager

infra team
  • Follow indicators representative for both IT and business interests; understand them and work together with the business to improve them.

  • Solve increasingly quickly any bug or slowness in your application. Discover how to gain visibility into your (complex) application.

  • Control the impact of any website update on the speed: your colleagues permanently put content on the website but what is the impact on the speed?

  • Manage risks linked to a cloud migration: avoid the classic remark “it was better before”

  • Guarantee the right IT budget spending: size your infrastructure in function of real bottlenecks; know your applications health to define development priorities
