A California man who co-founded a company that marketed itself as a green financial alternative has been sentenced for running a long-running fraud scheme. Joseph Sanberg, 46, was convicted after prosecutors said he used his stake in the company Aspiration to trick investors and lenders out of more than $248 million.

According to court documents, the scheme ran from 2020 through early 2025. Sanberg presented himself as a major shareholder in Aspiration, a company that promised to help people invest in environmentally friendly funds. But prosecutors argued that he lied about his ownership and control of the stock. He used those false claims to get loans and investments, often promising the shares as collateral. When the debts came due, the collateral was either worthless or did not exist.

The sentencing marks the end of a case that drew attention because of the company's high-profile mission. Aspiration had positioned itself as a socially responsible bank, with ads and marketing that focused on fighting climate change. Sanberg was a visible figure in that push, appearing at events and in media interviews.

Federal authorities said the fraud was not a small mistake or a temporary cash flow problem. They described it as a deliberate, years-long effort to steal money from people who trusted him. The judge handed down a prison term, though the exact length was not immediately released in full. Sanberg was also ordered to pay restitution to the victims.

The case serves as a reminder that even companies with a strong public mission can hide serious wrongdoing behind their branding. Investors are urged to verify claims about collateral and ownership before handing over money, no matter how noble a company's goals appear.
