The co-founder of Aspiration, Joseph Sanberg, was sentenced to 14 years in prison on Monday after defrauding investors and lenders of over $248 million.

The startup, an eco-friendly digital banking company boasting fossil fuel-free investments, carbon offsets for gas purchases, and a debit card with cash-back benefits for shopping at clean companies, was founded by Sanberg and Andrei Cherny. Cherny left the company in 2022 and has not been charged.

Sanberg, an Orange County native, pleaded guilty to wire fraud in October after being arrested in March last year. Aspiration subsequently filed for bankruptcy and liquidated all of its assets by July.

Sanberg and venture capitalist Ibrahim AlHusseini, who also faces charges, together forged a series of bank statements in order to obtain loans. From 2020 to 2021, the pair forged AlHusseini’s bank statements to show millions of dollars in assets in order to obtain millions of dollars from lenders.

Additionally, they forged a letter from their audit committee stating that $250 million in funds were available, when in reality Aspiration had less than $1 million. The amount of loans defrauded exceeded $248 million.

In 2021, Sanberg artificially inflated Aspiration’s 2021 revenue by $44 million by recruiting 27 fake customers to sign letters of intent pledging tens of thousands of dollars per month for tree planting services. Sanberg himself funded the contracts and used the inflated revenue numbers to obtain more loans.

The charges sparked an NBA investigation into salary cap allegations due to Aspiration’s connections with Clippers owner Steve Ballmer.

Ballmer personally invested $60 million in Aspiration, all of which was lost. He is now the target of a civil lawsuit alleging his participation in the scheme. Ballmer denies the allegations.

The team announced a $300-million sponsorship deal with Aspiration, and Clippers player Kawhi Leonard signed a four-year, $28-million marketing contract with the company, which reportedly performed no duties. The issue has raised concerns about how players are circumventing the NBA’s salary cap.

The team lost the $300-million sponsorship deal and an additional $20 million paid for carbon offset purchases.
