He spent that time putting together the former Tribridge and other acquisitions of DXC Technology as part of Eclipse, DXC’s Dynamics reselling and consulting unit. Gillis said he left DXC because the year-long integration was so demanding. Gillis founded Dynamics reseller Iteration2 and led it from January 2004 through April 2007 when it was purchased by Hitachi. He was SVP at Hitachi Consulting from April 2007 through March 2012 and then was president and global COO of the Business Solution Group for Hitachi Solutions Americas from April 2012 through July 2016.
