Indigo

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.
