Jonathan Mendelson

Analyst
An April addition to the DOGE lineup, Jonathan Mendelson has been part of Nate Cavanaugh’s wrecking crew that visits small independent executive agencies to subvert and destroy them. He has been spotted at the SEC and the USDFC so far, which is concerning considering he comes from a background in venture capital and investment banking. Prior to DOGE, he was an investor in the Silicon Valley VC firm Accel.

Interagency Coordination:
SEC leadership meets with DOGE representatives Jonathan Mendelson and Christopher Sweet to discuss using Sweet’s AI tool to identify regulations to cut or modify at the agency. It’s unclear if Sweet is detailed to the agency or just demonstrating the tool to SEC staff. Reportedly, agency staff then used the tool to identify thousands of regulations to cut. The list will then be reviewed by agency leadership and lawyers.
