We continue to supply practical charging stations to schools and organize the annual Teacher Summit — a full-day educational conference focused on modern technologies in education. In the Czech Republic, we have already worked with more than 500 schools, produced over 200 iKufrs, and organized 14 summits with a total attendance of over 1,800 participants.

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.

5 FileMaker Certified Developers

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.

The product we received from 24U has been helpful for us because it’s given us a competitive edge of some of our suppliers.
Duncan McDavid, Jacoma Estates

John Mikton, International School of Prague

The International School of Prague and 24U.cz have had an extremely positive collaboration in supplying IT and supporting our FileMaker Pro databases. We have used them to provide training, audits, troubleshooting, and consultancy for development of our databases. The professionalism, and outstanding customer service they provide is excellent. They provide creative solutions in a short timeline, and at the same time always very supportive both via phone and face to face.
John Mikton, International School of Prague

In one of our solutions we had a very complex recursive calculation that took ages to complete with large amounts of data. We decided to ask 24U to develop a plugin to manage that calculation and we went from tens of minutes to fractions of a second in getting the result. Now our clients love us and we now love 24U. Thank you!
Pep Espunyes, Andròmina eBusiness, SL

I came to know about 24U and in particular the software Xgode. Thanks to them and thanks to their professionalism, thanks to ease of use of Xgode, I was able to reach my goal at a very low cost. I must say that I was very satisfied with the professionalism and kindness of all the staff of 24U because in addition to e-mails were always very available, also by phone. So I really have to say thank you and I was very happy to have had the opportunity to "meet" them. I strongly recommend not only using Xgode to transform a program, software developed with FileMaker into an app.
Maurizio Accarino, TRE-COM srl

HOnza and 24U Software are a great resource for the FileMaker developer community. I always make it a point to read everything he posts on his blog.
Tom Fitch, Portland, Oregon

We are very very very happy with 24U’s custom development… It allowed us to concentrate on our FileMaker development instead of worrying about development in another environment.
Jeff England, Neb’s Fun World

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

For me, 24U is a reliable supplier of all the equipment we need. 24U has the advantage of not leaving me alone with the equipment. It's not like they just sell me some equipment and do whatever you want with it. They tell me what to do with that equipment in a way that I enjoy.
Jana Kneřová, ZŠ Plavy

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.

24U not only have a very good product but their technical team is very professional as well. Every time I asked 24U for technical help, they were very responsive.
Jacques Kirouac, Ewe Manage
