Austin Russell founded Luminar Technologies at 16, built lidar hardware in his parents' garage, dropped out of Stanford after three months on a Thiel Fellowship, and briefly became the world's youngest self-made billionaire at 25 when Luminar went public in December 2020. His company's 1550nm lidar sensors were integrated into production vehicles from Volvo and Mercedes-Benz, representing a rare case of autonomous vehicle hardware reaching mass-market cars.
