Grotto AI, founded by Nick Deveau and Ben Epstein, raised a $10 million seed round led by ICONIQ Capital to deploy AI-powered real-time coaching for leasing agents during calls and tours. The platform is already in use by Weidner Apartment Homes, which manages 70,000+ units, and aims to improve close rates by identifying revenue drivers and handling objections. This signals a shift toward AI augmentation of sales workflows in multifamily housing, where operator efficiency and conversion rates directly impact NOI and portfolio economics.
