They’re gunning for Goliaths. Lyft, with its strictly U.S.-centric market, is valued at less than a tenth of Uber’s $62.5 billion, thanks to its rival’s global domination. But the smaller San Francisco-based firm does have spunk … and friends in high places. Lyft has crafted partnerships with Starbucks, General Motors and ride-sharing leaders in China and India. Rather than trying to replace the $12 billion U.S. taxi market, Lyft’s slingshot is aimed higher — at the $2.15 trillion auto industry and private vehicle ownership.
