What a summer for Marissa Mayer. Besides taking over the floundering giant Yahoo after 13 years at Google as an engineer, designer and executive, she is expecting her first child (a boy) in early October. There are other babies to keep track of, too. Over the last few years Mayer, a 37-year-old Stanford grad (BS and MS, specialising in artificial intelligence), has been investing in promising startups. They illustrate her wide-ranging interests (from e-commerce to wireless electricity), as well as her throw weight in Silicon Valley (not everyone gets to co-invest with Andreessen Horowitz or to back Jack Dorsey). It’s an awful lot to shoulder—and all Marissa’s babies will be clamouring for quality mommy time. Company Name:natera
