The Women’s Pro Baseball League played its first season this summer, the first professional women’s baseball league in the United States since the 1950s. On the surface it’s a genuine comeback story: four teams, a shared home at Robin Roberts Stadium in Springfield, Illinois, and a championship series that ran into September. Underneath it, the league’s largest outside investor is suing in Delaware Chancery Court to force the release of financial records, alleging conflicts of interest and possible misuse of company funds. The nostalgia angle is real. It’s also not the whole story, and the part that isn’t is a lot more familiar to anyone who’s watched a founder-controlled startup run into its first real governance test.
Who actually owns the league
WPBL CEO Keith Stein, a Canadian lawyer at Dentons and a co-owner of the Toronto Maple Leafs in the Canadian Baseball League, holds roughly 65% of the company and says the league was his idea. Commissioner and co-founder Justine Siegal, a longtime advocate for women in baseball, holds a stake under 6%. The rest sits with a seed round of roughly $3 million raised over the winter of 2025, led by Mina Kim, an early Orangetheory Fitness investor who put in $500,000, the largest single check, alongside smaller investments including $75,000 from Rhonda Eiffe.
Kim was brought into the deal by board chair Assia Grazioli-Venier of Muse Capital, who according to Front Office Sports was later cut loose as an advisor after Stein ended the relationship, a move Grazioli-Venier disputes given her role in landing sponsors and press coverage for the league.
The $59,500 question
At the center of the dispute is a wire transfer of roughly $59,500 from WPBL to Ankeiste Ltd, an entity Kim alleges is owned by Stein and his wife. Front Office Sports and Brobible both report that the payment was first described internally as reimbursement for startup expenses, then later recharacterized as a loan, with no board approval or documentation on file for either version. Stein has said the transfer represented a portion of Eiffe’s $75,000 investment, which moved through a Dentons trust account and then through his personal account before roughly $59,000 was spent on tryout costs like insurance and hotel bills.
Kim also alleges that preferred share agreements were granted without proper disclosure to the board, something Stein says were added to the company’s records months ago; sources cited by Front Office Sports say the paperwork only appeared after Kim’s initial records request. None of that has been resolved by a court yet, and Stein disputes Kim’s account in full, calling her a “disgruntled investor” and suggesting he may move to remove her from the board.
A boardroom built by one man
Separate from the disputed wire, the structural details read like a checklist of what independent directors exist to catch. WPBL’s official address is a Dentons office in Toronto, the same firm where Stein practices law. The board includes Stein-appointed directors such as Dentons partner Andreas Kloppenborg, and, according to Brobible’s reporting, Mark Prosterman, who shares a surname with Stein’s wife, a family connection the league had not disclosed. League trademarks are reportedly registered under Stein’s personal name rather than the company’s. The corporate bank account wasn’t opened until December 2025, more than a year after the league says it was founded in October 2024.
Stein maintains the league holds a “healthy seven-figure” bank balance through the end of the season, that he has taken no salary, and that he has personally covered business travel without seeking reimbursement.
The court fight, and what it will actually decide
Kim’s filing in Delaware Chancery Court seeks records across 19 categories under the state’s books-and-records statute, a common mechanism for minority investors who believe a company isn’t giving them what they’re contractually owed. The case has moved to a paper resolution, with a decision on disclosure expected soon. It’s worth being precise about what that ruling can and can’t settle: a books-and-records order can force WPBL to hand over documents, but it doesn’t itself determine whether any funds were actually misused. That question, if it goes anywhere, would need a separate proceeding.
None of this is happening in a vacuum for the sport itself. On the field, the league says it sold more than 55,000 tickets across 30 regular-season games for roughly $1.3 million in ticket revenue, and that players and staff have been paid on time, with players earning $300 to $500 per game. Those are modest but real numbers for a first-year league, which makes the boardroom fight more consequential, not less: a league proving there’s fan demand is exactly the kind of asset that can’t afford a governance scandal at 65% ownership concentration.
Why this matters
Money has been pouring into women’s sports leagues faster than the institutional infrastructure to govern it, and WPBL is what that gap looks like up close. The Wage Bill has covered how MLB itself has spent decades building rules, however imperfect, around competitive balance and spending. A brand-new league with one shareholder holding a controlling stake, a board he largely appointed, and a corporate structure that took over a year to formalize doesn’t have any of that scaffolding yet. Investors chasing the next big women’s sports story would do well to ask who’s actually watching the books before they ask what the on-field product looks like.
