Before becoming an investor, Ari Helgason co-founded companies including Fabricly through Y Combinator, and he later built Transition alongside his brother David Helgason, keeping his path rooted in building rather than traditional finance. He maintains a strong connection to Iceland, serving on the board of Kría, the government's venture fund of funds, and he approaches climate investing broadly, writing about issues like plastics, pesticides, deforestation, and biodiversity loss alongside climate change, while unwinding through Muay Thai and finding inspiration in remote, off-the-beaten-path travel.

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.
