ATDOT LTD.
Senior IT consultancy for European organisations
Architecture, AI integration, Linux operations, and ethical technology design — without the overhead of a large agency.
About ATDOT
ATDOT Ltd. traces its origins to C.P.S.T. Ltd., founded in 1989, legally renamed to ATDOT in 2013.
Why "ATDOT"? ATDOT is a pun on the two characters present in every email address: AT (@) and DOT (.). The '@' separates the username from the domain; the '.' separates the domain levels. Since 1989, the company has worked with the technologies that connect people through these addresses.
Lorinc Czegledi has operated the company since 1999.
