Former Microsoft chief Steve Ballmer posted a scathing letter ahead of sentencing for Joseph Sanberg, the founder of Aspiration Partners who pleaded guilty to two wire‑fraud counts. Ballmer, who put $60 million into the green‑fintech venture, said the scheme left him financially drained and publicly embarrassed.

Sanberg’s company marketed sustainable banking products, promising to plant trees with every card purchase and touting a $2.3 billion SPAC valuation that never materialised. Prosecutors allege he fabricated audit‑committee letters showing $250 million in cash when the balance was under $1 million and faked revenue to secure $145 million in loans. The fraud exposed investors to massive losses and triggered an NBA inquiry into alleged salary‑cap violations linked to the Clippers.

Ballmer’s letter, shared on X, claimed the partnership also cost him a sponsorship deal for the Clippers and carbon‑offset programs at the Intuit Dome. He asserted that the scandal has spawned lawsuits and damaged his reputation, prompting his lawyers to reject a sports‑podcast series that suggested the firm helped skirt league rules.

The case serves as a cautionary tale for venture backers: fabricated financials can ruin portfolios, invite regulatory scrutiny, and drag high‑profile investors into legal battles. Investors now face the reality of total loss and reputational fallout.
