Bruis's background spans thermo-mechanical storage research at TU Delft, ocean wave energy at UC Berkeley, and data-driven battery lifetime prediction at Stanford/SLAC's Battery Informatics Lab, and he combines that research grounding with hands-on work, serving as a board advisor to UNIGRID, writing publicly about thermal runaway and sodium-ion safety, and once building his own map of commercial thermal battery projects by digging through press releases when he couldn't find one already made. He also works directly with Good Heat as part of its operating team while continuing his investing work at Transition, giving him a closer view of how energy storage technology actually gets built and deployed.

Notable Investments
Transition positions itself as India's first venture fund focused specifically on the energy transition, backing engineering-led hardware companies working on real energy infrastructure—like power electronics, batteries, and hydrogen systems—instead of software or general sustainability businesses, and it builds its portfolio around complementary rather than competing companies so founders can share supply chains and expertise. Its investors include many operators who have built and sold engineering businesses, giving startups direct help turning pilots into sales, and the fund also looks to bring energy research happening outside India into the country to set up local manufacturing for global markets.
