The ownership group, which is led by investment firm Sixth Street Partners and four former United States women's national team players, was awarded an expansion franchise on April 4, 2023.

It is the first women's professional soccer team based in the Bay Area since the San Jose CyberRays and FC Gold Pride, who both played in previous leagues.

Sixth Street CEO Alan Waxman and former national team player Aly Wagner were named the club's co-chairpersons.

Together the five women put together a board that included Tim Connors, Ward Bullard, and CJ Napolitano and raised initial capital from a small group of investors.
