The tennis star has been stuck on 23 Grand Slam singles titles since 2017 but remains a draw for advertisers, with nearly 20 corporate partners. She’s much more than a pitchwoman: In the last eight months, she has signed a first-look TV deal with Amazon Studios and picked up a board seat with a SPAC now taking 3D-printing company Velo3D public. She also has investments in 66 startups.
