Jason Blumberg runs both Energy Foundry as a venture capital investor and ISEIF as executive director, where he focuses on inclusive energy transition programs for seniors, low-income communities, and STEM access. He teaches future MBA and PhD leaders at the University of Chicago how to scale sustainable technologies and emphasizes that energy startups should get paying customers even in pre-commercial stages rather than waiting for full product development.

Notable Investments
Energy Foundry was created by Illinois law and funded by mandatory utility contributions to commercialize smart-grid technologies, operating as a nonprofit that recycles all returns into new deals rather than distributing profits to traditional investors. The fund works directly with utilities like ComEd and Ameren to test portfolio company technologies in real utility systems, giving startups access to regulated infrastructure as testing environments while serving as the implementation tool for Illinois' grid-modernization policy.
