ImmoSky

What ImmoSky does

ImmoSky AG is a Swiss-headquartered real estate brokerage firm founded in 2003, providing buying, selling, rental, and investment property services to individual consumers, property developers, and real estate investors in Switzerland, Germany, Austria, and France. The company operates through six physical branch offices spanning the cantons of Zurich, Aargau, Graubünden, Ticino, Vaud, and Fribourg, with its headquarters in Suhr and a service center in Dübendorf. Its core product surface comprises property search and brokerage (1,000+ active listings), online and professional property valuation powered by Wüest Partner's hedonic pricing engine, new-construction project marketing for developers, mortgage advisory via a network of nine Swiss financial institutions, and a SkyConnect client portal for transaction tracking. Marketing and buyer-engagement capabilities include professional photography, Matterport 3D virtual tours, drone footage, digital staging, and multi-portal distribution (ImmoScout, Immowelt, Homegate) plus social media channels including TikTok, Instagram, LinkedIn, Facebook, and YouTube.

The business model is a success-fee commission structure, where agents are paid only upon closing a transaction; commission rates are agreed with the seller in advance as a percentage of sale price, and no revenue is recognized unless a sale closes. ImmoSky is a privately held, independently owned company with no disclosed parent, subsidiaries, external investors, or M&A activity, and its two registered trademarks are ImmoSky and Starmakler. The company employs a personal-estate-agent-led go-to-market motion, supported by technology (SkyConnect portal, search subscriptions, online valuation, mortgage calculator) but without disclosed AI/ML capabilities; algorithmic property valuation is outsourced to Wüest Partner. Revenue is not publicly disclosed, and the company has not raised external funding.

Direct peers

• RE/MAX Switzerland: Global residential real estate franchise operating a large agent network across Switzerland. Directly competes with ImmoSky in the same customer segments (private buyers and sellers) using a similar commission-based brokerage model.
• Engel & Völkers: International real estate franchise with a strong Swiss presence focused on premium residential brokerage. Competes head-to-head with ImmoSky for mid-to-premium residential listings and investment property mandates across German-speaking Switzerland.
• Betterhomes: Swiss proptech-driven residential brokerage combining online valuation, listing, and transaction services. Directly comparable to ImmoSky for residential buy/sell mandates and competes on digital valuation and marketing technology.
• SPG Intercity: Swiss real estate company with offices across multiple cantons offering brokerage, valuation, and marketing services. Closely comparable mid-size brokerage competing for the same regional residential and investment mandates.
• Centonze Immobilien: Swiss residential and investment-property brokerage active across German-speaking Switzerland. Direct competitor for residential sales and investment-property mandates, with a similar customer base of SMB/individual sellers and buyers.
• Galliard Group: Swiss real estate firm specializing in residential and investment property brokerage in the Zurich region. Compares to ImmoSky on residential brokerage with overlap in developer and investor client work.

Others

• Wüest Partner: Swiss real estate research, valuation, and consulting firm that licenses ImmoSky's hedonic valuation methodology. While not a direct brokerage competitor, it is a key technology ecosystem participant and adjacent competitor for valuation services.
• Homegate: Switzerland's largest real estate marketplace and an ImmoSky distribution partner. Significant ecosystem overlap and increasing competitive overlap as the portal layers in adjacent brokerage and mortgage services.

Broad incumbents

• Cushman & Wakefield Switzerland: Global commercial real estate services firm with Swiss operations across brokerage, valuation, and advisory. A broader incumbent competing for higher-end residential investment and mixed-use mandates overlapping ImmoSky's investment-real-estate segment.
• CBRE Switzerland: Global real estate services firm active in Switzerland across investment sales, brokerage, and advisory. Comparable as a broad incumbent for higher-ticket investment-property transactions where ImmoSky's investment-real-estate arm competes.
