Ankur Jain believes that business can solve real-world problems. It occurred to the young entrepreneur that millions of renters spend the largest portion of their budget on rent - but can’t build lasting value off that money. His solution? Bilt Rewards, which lets tenants earn points on their rent that can be used for travel and other purchases – and helps them build a path to homeownership. Ankur comes from a family of business creators Bilt is his third company. He talks to Martha today about changing an industry and the challenges he met to make Bilt into a 3.1-billion-dollar company in less than two years.
