About us

We are converlytics!

converlytics GmbH, based in Berlin Karlshorst, was founded in 2011 with the aim of supporting online companies with sound expertise in web analytics and conversion optimization to increase their online success.

With the help of web analytics and conversion optimization, it is possible for companies, among other things, to increase their online sales, raise their level of awareness and improve the usability and thus the acceptance of their websites.

Today, converlytics supports not only the introduction and use of suitable analysis systems, but also the establishment of a holistic process of data-driven decision-making and business optimization based on statistically valid analysis data in companies.
