Overview
Zefir is a French proptech marketplace that speeds up real estate transactions by connecting homeowners with a network of partner agents and switching from an iBuying model to a collective sales approach. Homeowners list properties on the platform to reach a broader pool of qualified buyers, with a lead agent managing showings and negotiations; buyers are assisted by ZIA, an AI home-search tool, and brokers have AI-assisted automation to handle listing creation and routine tasks, while Zefir collects a fee based on the sale price. This setup differs from traditional single-agent listings by using a collective agent network to close deals faster and by integrating AI on both the buy and sell sides to reduce manual work. The goal is to expand in France and abroad, enhance its AI capabilities, grow its agent network, and increase annual home sales by making transactions quicker and easier for homeowners, buyers, and agents.
