Marc Tarpenning is Co-founder of Tesla and a venture partner at Spero Ventures. In 2003, Marc and Martin Eberhard saw two signals: GM killed its beloved EV1, and Californians snapped up Toyota’s Prius despite its compromises. They realized the market was ready for an electric car that was better than gas, not worse. Their breakthrough: 7,000 off-the-shelf laptop batteries powering a sports car that outran a Porsche and drove over 200 miles. The Tesla Roadster was born, before Elon Musk joined the company.
Marc shares how his time in Saudi Arabia exposed him to oil dependence, how NuvoMedia taught him about the pace of battery improvement, and why a software mindset helped Tesla out-innovate incumbents. Now at Spero Ventures, Marc backs founders building solutions that are both economically compelling and environmentally vital, and explains why, to him, EVs have already won.
