SAN FRANCISCO _ In the topsy-turvy world of tech, an investor can fund a company one minute and sue it the next. It can also turn around and fund a competitor, which is what Google's parent company did when it announced Thursday that its growth equity fund led a $1-billion investment in Lyft, four years after its venture capital arm invested in Uber.
The injection of cash increased Lyft's valuation to $11 billion, up from around $7.5 billion in April when it last raised $500 million from unnamed investors, and up further still from its $5.5-billion valuation last year.
