# 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.

- **Founded:** 2019
- **Headquarters:** Bengaluru, India
- **Founders:** Murari Ramkumar (Founder & CEO), Dr. Nagesh Kini (Co-founder & CTO)
- **Team size:** ~16 employees
- **Products:** Redox flow battery membranes, AEM electrolyzer membranes, Fuel cell membranes, Thermal management polymer films
- **Notable:** Raised INR 25 Cr (~$2.9M) seed led by Ankur Capital (2025), Scaled membranes ~100x from 25 cm2 to 2500 cm2 within two years, Reported ~99.7% efficiency and high capacity retention in flow-battery testing

## Products & services

- **Redox flow battery membranes** — Ion-selective membranes for long-duration energy storage that reduce ion crossover; the company reports high capacity retention (cited at ~15.7x) and ~99.7% efficiency in flow-battery testing.
- **AEM electrolyzer membranes** — Anion exchange membranes for green hydrogen generation, engineered toward state-of-the-art performance without per-fluorinated chemistry.
- **Fuel cell membranes** — High-temperature PEM-style fuel cell membranes for hydrogen mobility; Vimano cites up to 35 km of additional range per 100 km for hydrogen trucks.
- **Thermal management polymer films** — Polymer films for thermal management applications, including satellites and space technology, spun out of the same advanced-materials platform.
