Wesupply is headed by CEO David Grosvenor who has been in that position since December 2010. This is the fourth HighJump acquisition in 14 months. In July 2014, the company, then called Accellos, bought HighJump Software and adopted the acquired company's name. Later that month, the newly named HighJump purchased Atlas Products, a U.K.-based e-invoicing and EDI company. In May, it picked up Nexternal, a Carlsbad, Calif.-based ecommerce platform provider. HighJump has been making these moves as a portfolio company of Accel-KKR.
