Essmart sells a wide range of vital technology, like solar lighting and smoke-reducing cook stoves, to rural communities in India. It does this by getting those products to 15 million local retail shops which it says count for 90 per cent of India’s $550bn annual retail spend. It has partnered with eyewear company Essilor, which is supplying it with low-cost reading glasses and UV-protective sunglasses, and has shifted 4,000 units of its products to date. As part of the collaboration, Essilor has trained Essmart’s field staff.
