Zefir operates a digital platform that federates local agents around a single transaction to execute collective home sales, claiming access to about 95% of potential buyers. After pivoting in 2022 from a guaranteed-sale model to the collective-sales approach, the company reports strong growth: transactions rose from €200M to over €600M in one year and annual activity multiplied by three. The site lists more than 100,000 properties and the startup says it sells roughly twice as fast as the market average. Zefir is launching “ZIA,” a conversational AI real-estate agent currently offered for free to assist buyers and sellers and to make the platform more personalized. The company states it is operationally profitable on a per-transaction basis but remains loss-making at the corporate level while continuing to invest for growth. Planned priorities include expanding into about fifteen additional cities beyond Paris, Lyon, Lille and Nantes, doubling headcount, and strengthening technology to sustain growth above 2x per year. Zefir operates a collective sales platform that accelerates connections between home sellers and buyers and fosters cooperation among real estate agents. The platform divides roles among multiple agents, ensures fair compensation, evaluates agent performance, and centralizes a network of buyers and properties. Led by co-founder and CEO Remy Fabre, the company aims to streamline transactions through collaboration rather than exclusive listings. Zefir plans to use new funding to expand operations and invest in its online platform, including applying artificial intelligence to better serve customers and agents. The company also intends to triple its property portfolio and its network of real estate professionals. The financing provides capital to support these growth and product-development initiatives.
