Marissa Mayer's Next Act Is Here

When Marissa Mayer decided to start her own company, after nearly five years as Yahoo's CEO and 13 years at Google, she turned to her rolodex of contacts. For a startup in its early stages, success often has less to do with what you're building than who is building it. And Mayer, one of Silicon Valley's marquee names, had a lot of numbers she could call. There are over 14,000 people stored in her iPhone. So it's not surprising that Mayer assembled a fine team at Lumi Labs.
