Sohum Innovation Lab develops market-driven solutions to improve the health and incomes of people living in resource-poor settings. We are a group of designers, engineers and business people. We do front line research and develop technology and strategies, that create self-sustaining value chains among the under-served. We identify unmet needs that can create wide-spread social impact and develop indigenous technology and business solutions to meet them, such as the need for hearing screening in developing countries. We are creating and deploying an integrated approach involving an awareness campaign and technology innovation to answer this need.
