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.
