Indigo is an AI-powered home transaction platform that reworks the messiest part of buying and selling a house: the offer and the paperwork behind it. Built by the founding team behind Ribbon, the New York startup replaces the email-and-PDF scramble with real-time offer dashboards, AI-generated and compliant contracts, and shared deal rooms for agents, buyers and sellers. It raised an $8 million seed round in January 2025 and says it topped 20% of home offers in its first markets within three months of launch.
Shaival Shah is the co-founder and CEO of Indigo, an AI-powered home transaction and offer-negotiation platform for real estate agents, buyers and sellers. A repeat proptech founder, he previously built and led Ribbon, the all-cash offers platform that handled roughly $20 billion in offers a year. The son of Indian immigrants who needed a community loan to buy their first home, Shah builds technology aimed at making the most complex, opaque part of real estate, the contract, transparent and fair.
