Anne Wojcicki
Sergey Brin is the other Google co-Founder, but his marriage only lasted until 2015. His ex-wife, Anne Wojcicki, stood behind him and provided him with eight years of support. She, however, has also managed to make a name for herself. Wojcicki co-founded 23andMe, a renowned personal genomics company, where she also holds the position of CEO. The pair, when they were together, had an estimated net worth of $ 40 billion.
