Vimano
Vimano is a Bengaluru-based deep-tech startup building PFAS-free, ion-selective nanotech membranes for the electrochemical devices that power the energy transition - redox flow batteries, AEM electrolyzers, and hydrogen fuel cells. Its proprietary membrane platform tackles the ion-crossover problem that limits efficiency in long-duration energy storage and green hydrogen, and it also adapts the same polymer-film science to thermal management films for satellites. The company's stated goal is to sit inside 1 out of every 2 large-scale energy storage devices, electrolyzers and fuel cells on the planet.
Chris Holmes
Chris Holmes is the President and CEO of AvCarb Material Solutions, a Lowell, Massachusetts maker of engineered carbon materials - the felts, fabrics, and papers that quietly sit at the heart of hydrogen fuel cells, electrolyzers, and flow batteries. An MIT-trained systems engineer with a hybrid technical-and-business background, he is a turnaround specialist who has led high-technology businesses from start-up scale to north of $200M in revenue, largely inside private-equity portfolios. At AvCarb he is steering a company with 1960s roots toward the center of the clean-energy transition.
Murari Ramkumar
Murari Ramkumar is the founder and CEO of Vimano, a deeptech materials startup building PFAS-free, ion-conductive membranes for flow batteries, green-hydrogen electrolyzers and fuel cells. A materials scientist trained at NITK Surathkal and the University of Pennsylvania, he co-founded the company in 2019 with Dr. Nagesh Kini and is chasing an audacious goal: to put a Vimano membrane inside one of every two large-scale energy storage devices, electrolyzers and fuel cells on the planet. In 2025 Vimano raised roughly $2.9 million in seed funding led by Ankur Capital.
