zSpace builds headset-free augmented and virtual reality learning systems that let students hold and manipulate lifelike 3D objects on a laptop or all-in-one screen using a stylus and head-tracking glasses. The platform powers STEM and career-and-technical-education programs - from dissecting a virtual frog to wiring a circuit or exploring human anatomy - in thousands of U.S. school districts and 50-plus countries. Founded in 2007 as Infinite Z and renamed zSpace in 2013, the San Jose company went public on the Nasdaq in December 2024 under the ticker ZSPC.
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.
