Marissa Mayer is an American information technology executive, businesswoman and investor who is the co-founder of Lumi Labs, a technology incubator focused on consumer internet technologies. She served as the president, chief executive officer and a member of the board of directors of Yahoo! for five years, during which time she increased the platform's mobile user base by reinventing it for improved mobile experience. However, as the shares of the company continued to drop during her tenure and it was eventually acquired by Verizon Communication, she was not retained to join the new combined company Oath (now Verizon Media). She previously spent 13 years at Google where she designed the homepage and improved Google Search, apart from contributing to various key decisions for almost every product offered by the company, including Google Maps, Gmail and Google News. She has been named among most powerful people in the business industry several times by various media outlets over the years.
