Connected vehicles are transforming fleet operations across industries, led by the electric revolution. EVs were the first truly software-defined vehicles, and businesses are rapidly adopting them but lack the software infrastructure to unlock their true value. Our mission is to build the fleet management platform for the electric vehicle era - becoming the default software layer that empowers fleet operators to maximize efficiency and profitability. Our team is backed by top Silicon Valley investors and was founded by the CEO of Embark, a transportation start-up acquired by Apple. We’re a group of ex-Apple, Stripe, Yelp, Robinhood, and Tesla engineers, designers, and business professionals who want to have a meaningful impact on the world. If you’re curious, say hello!
