Zefir

Zefir operates a French real estate platform built around "Vente Collective" (collective sale), where a seller's property is marketed by the combined network of local agents, and an AI assistant (ZIA) supports buyers searching listings and sellers estimating prices.

The platform serves home sellers, buyers and real estate agents. Sellers get a free-form property estimate and a tracking dashboard; agents can join the Zefir Connect partner network to receive mandates and buyer leads, which the site describes as free to join. The site does not state how Zefir is paid.

The website is published in French and cites a network of 3,500 partner professionals and more than 3,100 satisfied clients; it lists Paris-based roles in its open positions. Founding year and headquarters address are not stated in the provided text.
