OUR IDENTITY

The Future  Needs Mavericks

We were born in Chicago—a city forged by fire and fueled by reinvention. Like the river that runs through it, we go against the flow. We don’t follow trends. We challenge them.

Undercurrent is powered by people who don’t wait for permission. Scientists. Engineers. Designers. Builders. People who looked at a broken energy system and said, there has to be a better way.

If you’re here to work on real problems with real stakes—and reshape what energy can do for the world—this is your moment.
