Industry

D. Thiébaut is one of the five co-founders of Gemicer, which after changing its name to Connex Technology, has now adopted the current name of BrightScale.

D. Thiébaut is the holder with George Stefan of two patents, one of which (US Patent 6,760,821) the company is based. Connex Technology/BrightScale is a fab-less start-up company conceived in April 2002, and funded by Adams Capital Management (www.acm.com) in April 2003.

More information on the history of the Connex Engine can be found here.
