Steve Ballmer blasts founder he backed who pleaded guilty to fraud: ‘I was duped and feel silly’

Silicon Valley tends to tolerate a certain amount of founder exaggeration when pitching investors, often dismissing it as part of selling a vision. But some choices cross the line and can lead to jail time for founders and scandal for their investors. A case in point is Joseph Sanberg, whose once high-flying fintech startup Aspiration Partners was backed by a roster of tech celebrities, including former Microsoft CEO and current Clippers owner Steve Ballmer. In August 2025, Sanberg pleaded guilty to two counts of wire fraud and defrauding multiple investors and lenders, the U.S. Department of Justice said in a press release. Each count carries a maximum sentence of 20 years in prison.
