Paul Kellenberger

Paul Kellenberger is the CEO and President of zSpace, Inc., a San Jose-based company that pioneered display-based augmented and virtual reality for education. Rather than strapping headsets onto students, zSpace built a 24-inch 3D screen with head-tracking and a haptic stylus - no goggles required. Under Kellenberger's leadership, zSpace expanded from zero revenue in career technical education to 50% of its pipeline in that segment, served over 2,400 U.S. schools, and took the company public on Nasdaq in December 2024 under ticker ZSPC. With more than 70 patents, research partnerships with NC State showing 40% better retention rates, and recent acquisitions of BlocksCAD and Second Avenue Learning, Kellenberger is pushing immersive learning into the mainstream of American education.
