About Gaurab Chakrabarti

Gaurab Chakrabarti's path to venture came from his own research discovering how an enzyme could turn sugar into hydrogen peroxide, which led him to build a chemical manufacturing company focused on smaller, local plants, reliable delivery, and pricing that competes on its own merits rather than a green premium. He also brings a hands-on, partnership-minded view of industry—preferring to work with large manufacturers rather than compete against them—and speaks often about rebuilding U.S. manufacturing, including ties to defense and other real-world customers.

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.
