In 2014, she started her own venture fund Serena Ventures, which "invests in companies that embrace diverse leadership, individual empowerment, creativity and opportunity." Some of these companies—Billie, HoneyLove, Floravere and Brandless, among others—which she's invested in within the last five years, are founded by women and minorities.

“I want to be a part of it,” she said during her interview. “I want to be in the infrastructure. I want to be the brand, instead of just being the face.”

She is also the very first athlete to have this honor and make the list

Alexis, who is the co-founder of Reddit and has an estimated $70 million net worth, met Serena in 2015 and now have one child together Alexis Olympia Ohanian Jr. “I’ve been really leaning on Alexis,” she shared, while Alexis praised his wife's ambition. “She is determined to be great at everything she does.”
