About IO Datasphere

IO Datasphere is a leading provider of management and IT consulting services delivering results-oriented solutions focused on client business goals and objectives.

IO Datasphere was founded in November of 1996 by Wally Markovic and immediately began work on a contract with The Delos Company to provide Komatsu America International Co. with an electronic catalog and competitive information analysis product. This cost effective solution, initially delivered on CD-ROM and later to the Internet, was a huge success that provided the sales force with up-to-date product information on all heavy equipment product lines along with information on comparable models for major competitors.

IO Datasphere has grown and evolved into a full-service IT consulting and software development firm. Mr. Markovic has led this effort, first providing software development services to companies in the Metropolitan Chicago area, and then expanding into staff augmentation and software development services for businesses, state agencies, and local government in the Midwest and throughout the United States.
