Listen to your customers, solve, and implement. For the cofounders of the milk delivery startup, these early business lessons still resonate. “We don’t come from a background in milk production. Direct consumer feedback has taught us whatever we know,” says Gade (right). The firm was founded in 2013 by Gade and his IIM Indore batchmate Kaushal to solve the problem of adulterated milk. Their weapon: a fully integrated tech platform backed by an app-based subscription service to deliver fresh milk and dairy products to the consumer’s doorstep. It has raised $12 million so far from investors such as Matrix Partners.
