Founded in 2009 by JoeBen Bevirt on his family's Santa Cruz ranch, Joby Aviation builds the S4, a five-seat eVTOL air taxi with six tilting prop-rotors, roughly 150-mile range, and 200 mph cruise. The company went public on NYSE in August 2021 via SPAC merger with Reinvent Technology Partners. Toyota has committed $894 million across multiple tranches and now holds Joby's largest equity stake. In March 2026 the FAA cleared Stage 4 of type certification, putting commercial launch on track for late 2026 with Delta in New York and Los Angeles, alongside service rollouts in Dubai and Saudi Arabia.
