Zefir is a French proptech marketplace that speeds up real estate transactions by connecting homeowners with a network of real estate agents through a collective sales model. Homeowners list properties, which are exposed to a broader pool of qualified buyers via partner agents, with a lead agent handling viewings and negotiations; the platform charges a take rate as its fee, and buyers get an AI-powered experience with ZIA, while brokers receive AI-assisted task automation. Unlike traditional single-agent listings, Zefir leverages a network of agents and AI on both the buy and sell sides to speed deals and reduce manual work. Its goal is to expand across France and beyond, grow its AI capabilities and agent network, and increase annual home sales by making the process faster and easier for homeowners, buyers, and agents.
