Co-Founder & CTO, Promethean Power Systems



Sorin Grama is the Co-Founder and CTO of Promethean Power Systems, which provides people in the developing world with technology for preserving perishable foods. Promethean’s main focus is chillers that allow cows’ milk to find a market beyond the immediate vicinity of rural dairy farmers.

Promethean works  with dairy processors to install milk chillers  in India, Sri Lanka and Bangladesh. Each installation makes a huge difference to its community, something that Sorin didn’t really see coming. “When I first set out to do this I just set out to solve a technical problem,” he says. “Now I see the bigger impact.” The milk collection centre becomes a hive of activity, with people coming in twice a day to deposit their milk. “They’re making good money, and that leads to development in the villages.”
