Haley Rosen was a collegiate soccer star at Stanford University, and went on to play professionally both in the US and Europe. But after an injury-shortened career, she moved back to Silicon Valley to work in tech. But motivated by the dearth of coverage of women's sports -- 44% of athletes are women, yet they only garner 4% of sports coverage -- she kicked off an Instagram page called Just Women's Sports. The page attracted a following, and convinced Rosen it could be scaled into a business. The solo founder and her team have now attracted a rabid fan base and venture investors including Spark, Andreessen Horowitz, Greycroft, and yes, 35 Ventures. Rosen talks to Rich and Gianni about how the rising visibility of women's sports and athletes in 2020 helped fuel her business launch; her appreciation for Kevin Durant's enthusiastic support for the platform, and much more.
