Elon Musk did not start Tesla. Martin Eberhard and Marc Tarpenning did, founding Tesla Motors in 2003 and running it as CEO and CFO before Musk ever joined the company. CNBC sits down with both men for an exclusive interview covering the early years: the battery technology that made an electric sports car plausible, the scramble to build the Roadster, and the boardroom shifts that eventually pushed Musk into the driver's seat and pushed them out. The film traces how a company now defined by one billionaire's public persona actually began as a small engineering bet by two Silicon Valley veterans, and how that origin story got rewritten in the retelling. Archival footage and present-day interview segments track the company from its founding through its transformation into the dominant electric automaker, giving credit and context that the popular Musk-centric narrative usually skips.
