Our beginning

1E was founded in 1997 by Sumir Karayi. Highly technical and with many years of experience in blue chip organizations, Sumir saw a need to reduce the cost of managing Windows PCs and Servers.

Driven by word of mouth validation from our customers, 1E gained a reputation as the leading Microsoft Systems Management specialist, supporting our customers in robust content distribution, software asset management, and user self-service. In addition, 1E was a pioneer in PC Power Management and Green IT well before these became hot topics, helping companies reduce their waste at the same time as saving them money.


Our name

People often ask us where the name came from…and there have been many suggestions put forward over the years. The definitive origin of the name is from a BSOD Windows error:


Back in the early days, this was the favorite error code of the founders, one which they helped clients avoid.
