Here's a brief overview of technologies and tools we use every day:

Claris Platinum Partner

We provide consulting and resell the FileMaker platform licenses since founding the company. We joined the FileMaker Solutions Alliance in July 2002 and remained well known member when it was renamed to FileMaker Business Alliance. In October 2016 we became a platinum level partner. In 2019, when FileMaker Inc. got renamed to Claris International, we became Claris Platinum Partner.

30 years of experience with the Claris FileMaker®

HOnza Koudelka, co-founder of 24U and head of the 24U Software, developed his first Claris FileMaker solution back in 1991 (back then it was called FileMaker), nine years before founding 24U. He remains the consultant for our whole FileMaker development team, sharing all his knowledge, and even won the FileMaker Developer Cup at FileMaker DevCon 2015, so the expertise we are offering to every customer is a real non-cumulated experience that goes far beyond the existence of our company.

We let our developers learn fast and from the best experts. Thanks to our internal training strategy every member of our FileMaker team achieves the FileMaker’s certification and then keeps it current with future versions going forward.

ISO 9001 Certified

Since April 2004, 24U is ISO 9001 certified for design, development, customization and implementation of software. Updated to the ISO 9001:2015 standard since March 2018.

24U built us a comprehensive system to monitor and develop the academic and financial relationships between the college and its students. This custom system has been integrated to our financial, invoicing and CRM systems in a way that is excellent. My only regret is that we did not start the process with 24U many years earlier!
Douglas Hajek, Prague College

We were trying to connect some older equipment and get data from it to FileMaker and we had no idea how to do it. I would recommend 24U to anyone who have a tricky problem. because 24U really help me to figure it out and I was surprised they could do it!
Craig Cutler, OD

We were pleased with the inventivity of 24U developers in response to some of our very specific needs. Our complete all-in-one solution allows us to quickly manage and view our data in all of its relationships. With people at various locations, remote access is vital for us and has proven highly useful.
Ruud van Donselaar, Dartin spol. s.r.o.

Iva Jelínková, Speciální škola Poděbrady

We have been working with 24U from the beginning, because it was the people who trusted us, who had a dialogue with us from the beginning, and we were helping each other. At 24U, I really like that they are extremely flexible, they are not afraid of any idea, however they are insane, and they are not afraid of going into everything with us.
Iva Jelínková, Speciální škola Poděbrady

Thank you for your awesome support and getting us started. Much appreciated!
Bruce Berry, ACTIVE Manufacturing Corp.

Graham Lindsay, BIAB, Kingston, Ontario, Canada

Where 24U I think is different than a lot of other companies is its interest in the FileMaker world and supporting FileMaker users and particularly when I needed some custom work done they were there to solve my problem. I could not have been more satisfied with the whole process of having a custom development undertaken by 24U. The sales and technical staff were responsive, customer oriented and thoroughly professional.
Graham Lindsay, BIAB, Kingston, Ontario, Canada

24U developed a super clear CRM for our company and we could have thrown away Excel. Everything was done relatively quickly. What I appreciate most is the ease of transition and tweaking of the system.
Michal Mag, MyTimi

We have always been satisfied with 24U's services. They are professionals with very good knowledge in their field. In addition, it was fun with their programmers and no problem was serious. 24U services brought us an increase in work productivity through the availability of information in a unified system, the elimination of duplicate administrative work, easier setup of work processes and procedures.
Vladislav Ptašnik, CompoTech Plus

Thanks HOnza! Things are going well for us - we are very busy. The door badge integration with Gonector has worked very well. The iPads on our presses continue to perform well - I’ve added a pic showing our typical setup. A lot happens on each iPad with paper roll scans, labels, counts, speeds and time. Gonector helps keep it connected and works in single app mode.
Alan Meinhart, Three Z Printing

Donovan Chandler, Beezwax Datatools, Inc.

I am excited to be playing with 24U FM Bench to really take the solution to the next level.
