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.
