Boundary Stone Partners was founded by two former Chiefs of Staff at the United States Department of Energy. They served during a period of transformative technology innovation, government investment, and crisis that put them in the center of the action. 

Collectively, our team has approved and closed tens of billions of dollars in clean energy transactions, developed federal policy, helped U.S. companies navigate foreign markets, managed federal research, development and deployment programs, and raised capital. We have held senior positions at the White House, the Department of Energy, the Department of Commerce, the Department of Transportation, Congress, and major investment banks.
