Accel-KKR invested $105m in Vistex, a Chicago-based global software company. Vistex serves businesses of all sizes around the world, enabling mission-critical processes that manage trade, channel and vendor programs, pricing, performance incentives and rights and royalties. "This is the first equity capital raise in the history of the company. It is unprecedented for an enterprise software company to grow to a size and scale like Vistex without any external capital. Together, Vistex and Accel-KKR will focus on the company's next stage of growth and accelerate progress towards achievement of its strategic objectives," Sanjay Shah, who founded Vistex in early 1999 and has been the Chief Architect and CEO since its inception.
