Background: Marissa Mayer started her career at Google and served as the CEO of Yahoo from 2012 to 2017. Mayer cofounded Lumi Labs, an "early-stage technology studio," in 2018.
Leadership style: When asked how she rises above criticism in the press at a talk at Stanford's Graduate School of Business, Mayer said, "I don't read it. That might sound tone deaf, but I feel like if you read it, it changes who you are and how you think about things ... to make decisions, or allow your decision-making to be influenced by a third party who has a fraction of the information that you have, overall isn't a great strategy."
Fun fact: At Google, Mayer was employee No. 20 and the company's first female engineer.
