Let's say you run a well-funded startup in the super-hot virtual reality sector. What would you do -- bask in your success? Don't tell that to Jaunt CEO Jens Christensen. After just three years at the cinematic VR company he helped create, Christensen is stepping down to "move on to [his] next adventure." The company didn't explain the move in a statement to Fast Company, but Christensen is known as a "serial entrepreneur" that doesn't sit still for long. Most likely, he's off to make the next big thing.
