Officially announced as the WNBA’s 14th team in May 2024, the Tempo are the league’s first team based outside of the United States. They will begin play in 2026.

The team said Williams’ role will include “bringing the Tempo to life visually,” including active participation in future jersey designs and forging new merchandise collaborations.

“Serena is a champion,” team president Teresa Resch said. “She’s the greatest athlete of all time, and her impact on this team and this country is going to be incredible. She’s set the bar for women in sport, business and the world — and her commitment to using that success to create opportunities for other women is inspiring — we’re thrilled to be marking the lead-up to International Women’s Day with this announcement.”

Williams’ investment in the Tempo is still pending final league approval, the team said.
