About JAM Software

It all started with the question "How to manage disk space more efficiently?". During his studies, Joachim Marder found an answer to this question with the product "TreeSize". And the history of JAM Software began. Today, over 20 years later, we at JAM Software employ more than 30 employees in our headquarters in Trier, Germany.

We are specialized in developing solutions for system administrators and offer our customers a broad product portfolio in the fields of Disk Space Management, Mail Server & Security and Server & Network Monitoring. Furthermore, we develop solutions for Banking and Developer Components to integrate Windows functionality into your own programs.

Our solutions are distributed via our JAM Online Shop and a global network of international resellers. All of our software solutions can be tested with their full functionality for 30 days, free of charge. 80 percent of the top 100 companies in the world are among our customers.

"Thank you for investigating our needs and asking relevant questions. It's a pleasant change from most vendors trying to oversell their products!"

Damon Plackard, Infrastructure Architect, Leading Building Products Manufacturer, USA

"Thank you so much for your kindness and making my purchase so easy. I know you didn't have to and there are very few companies out there that would have gone the extra mile you did to give your customers and resellers a no hassle buying experience.
I like your company already and look forward to selling your products. Have a wonderful weekend."

Mazen Khatib, Maztec

"I just updated to the latest version. Great software... I used it when I worked at Boeing on the SLS program. Very useful for hunting down large files in particular folders. I don't use it often, but when I do it is always reliable, and fast. As a retired aerospace software engineer I appreciate good software. Thanks Again!"
