What makes Google unique, compared to the other companies featured on this list, is that its co-founders are relatively close in terms of total wealth. Sergey Brin’s involvement in Google follows a similar path to Page’s. After the duo founded the company in 1998, Brin served as co-president alongside Page until Eric Schmidt took over as CEO in 2001. Similarly, after founding Alphabet in 2015, Brin acted as the holding company’s president before stepping down in 2019 when Sundar Pichai took over as CEO.
In addition to being a highly popular search engine, Google also offers a suite of online tools and services, known as Google Workspace, which includes Gmail, Google Drive, Google Calendar, Google Meet, Google Chat, Google Docs, Google Sheets, Google Slides, and more. In addition to software, Google also deals in a wide variety of electronic devices, including its Pixel smartphones, its Pixelbook computers and tablets, its Nest smart home devices, and its Stadia gaming platform.
Brin spent much of 2019 focusing on X, Alphabet’s “moonshot” research laboratory, which is responsible for innovative technologies like the Waymo self-driving cars and Google Glass smart glasses. He has also donated millions of dollars toward researching a cure for Parkinson’s and partnered with The Michael J. Fox Foundation to devise new drugs against LRRK2, one of the greatest genetic contributors to the disease.
