What Zefir does
Zefir is a French proptech founded in 2020 by Rémy Fabre and Louis Lambert, operating a real estate platform that pairs a "Vente Collective" (collective sales) model with AI-powered buyer search tools. The company targets structural inefficiencies in the French residential market, where sellers traditionally rely on a single agency's limited buyer network for 90-100 day sale cycles at 5-8% commissions. Under Zefir's model, a single mandate grants the seller access to the combined buyer networks of all top-performing local agents in the area, achieving an average 58-day sale time at a flat 4.99% all-inclusive commission paid only upon successful closing. The legal operating entity is VESTA SAS, headquartered in Saint-Mandé, France, with an additional Paris office.
The platform serves three interconnected segments: homeowners selling residential property, prospective buyers, and independent real estate agents. Core technology includes ZIA™, an AI-powered natural language search assistant that interprets conversational buyer queries, filters and deduplicates property listings in real time, and delivers personalized matches; a real-time seller dashboard tracking visits, buyer feedback, and offers; and the Zefir Agent App, which integrates with Gmail to automate buyer inquiry processing. A network of 4,500+ partner agents, recruited via the no-upfront-fee Zefir Connect program, forms the distribution backbone of the collective sales model and the supply-side moat.
Zefir has surpassed €1 billion in cumulative transaction volume across four years and reports an annualized transaction run-rate of €600M as of September 2025, with the company stating it "triples in size each year." Revenue mechanics are transaction-based, with the 4.99% commission split between Zefir's platform and participating agents. The company has raised approximately €50 million across four funding rounds — a 2021 seed led by Stride.VC, a €20M Series A in February 2022 led by Sequoia Capital, an €11M Series B in April 2024, and a €15M round in September 2025 led by FinTech Collective — with plans to double headcount by 2026 and expand Vente Collective into the top 100 French metropolitan areas.

Revenue model
- Transaction Commission (Success Fee): Zefir earns a 4.99% all-inclusive commission on successful property sales, covering both Zefir's fees and the agents' remuneration. Payment is only triggered upon successful transaction completion. This is the primary revenue stream and positions Zefir as a cost-effective alternative to traditional agencies (5-8%). The commission is split between Zefir and the participating agents in the collective.

Zefir competitors and assessment
Company assessmentDirect peers
- Proprioo: Paris-based French proptech offering a flat-fee real estate service for sellers, combining online estimation tools with partnered local agents. Directly competes with Zefir on price-transparent, tech-enabled residential brokerage in France.
- IAD France: France's largest network of independent real estate agents operating on a shared-commission MLM-style model. Comparable to Zefir's Vente Collective in that it aggregates independent agents under a single brand to sell residential property at lower fees than traditional franchises.
- Bien'ici: French property search portal jointly backed by major real estate groups (SeLoger, LeBonCoin, BPCE). Competes with Zefir Search on buyer-side property discovery and listing aggregation in the French market.
- Purplebricks: UK-founded hybrid estate agency that pioneered flat-fee seller models with partnered local agents. Direct conceptual peer to Zefir — historical cautionary tale demonstrating execution risk in cross-border proptech expansion.
Broad incumbents
- SeLoger: France's leading online real estate portal with millions of listings and deep agent relationships. Competes with Zefir on buyer-side traffic and listing distribution, and could launch competing collective-selling or AI-search features.
- LeBonCoin: France's dominant classifieds platform with a large real estate vertical. Operates at much broader scope than Zefir but overlaps directly on property listing discovery and seller/buyer matchmaking.
- Compass: US tech-enabled residential real estate brokerage combining an agent network with proprietary technology. Comparable to Zefir as a model for how a digital-first brokerage can scale, though operating in a much larger and more mature US market.
- Redfin: US discount brokerage with technology-led buyer tools, AI-assisted search, and in-house agent model. Closest international analog to Zefir's tech-augmented, lower-commission positioning for buyers and sellers.
- Opendoor: US iBuyer that uses technology to streamline residential transactions and offer instant liquidity to sellers. Also an early investor in Zefir's Series A; comparable as a tech-enabled real estate transaction platform with a fundamentally different (instant-buying) operating model.
Emerging players
- Loft: Brazilian proptech operating a tech-enabled brokerage and liquidity platform. Investor in Zefir's Series A; relevant as an emerging-market peer pursuing similar transaction-fee economics with a tech-augmented agent network.
