What Immounited does

IMMOunited is a Vienna-based real estate data and portal platform founded in 2007, focused exclusively on the Austrian market across all nine federal states (Wien, Niederösterreich, Steiermark, Oberösterreich, Burgenland, Kärnten, Salzburg, Tirol, Vorarlberg). It operates a hybrid B2C/B2B model: the consumer-facing immounited.com portal offers property search, saved searches, and listing management, supplemented by the CheckIMMO and bodenpreise.at sub-brands for consumer valuation and land-price information, while the B2B business portal (business.immounited.com) distributes a suite of professional products including IMMObase, IMMOmapping, IMMOstats, IMMOvaluation, IMMOfarming, IMABIS, IMMOdeveloper, and the IU2GO mobile app. The platform lists approximately 9,879 immovable properties across 802 projects and 2,437+ land parcels, with named listing customers such as Raiffeisen Immobilien, DECUS Immobilien, Immo-Company Haas & Urban, Zeininger Immobilien, ALTERA real estate, and MAST Immo.

The company's core technical differentiator is the AI-supported Preis-Check feature, which produces automated market-value estimates by comparing registered purchase contracts from the Austrian land registry (Grundbuch), deriving €/m² reference ranges, and enriching the result with a precise location profile covering distances to public transport, schools, kindergartens, and supermarkets. It also publishes the OpenImmo Validator, an online developer tool that validates OpenImmo 1.2.7c XML feeds and provides code-generation samples in C#, Java, PHP, Python, Node.js, Go, and Rust, embedding IMMOunited in the broader Austrian real estate software ecosystem.

IMMOunited monetizes through B2B software subscriptions (professional tools for agents, developers, and property managers), transaction-based portal listing fees, and a freemium B2C channel. No public pricing tiers are disclosed; the B2C portal is explicitly described as 'Kostenlos & unverbindlich' (free and non-binding), while B2B pricing is contact-based. In March 2025, the company was acquired by Munich-based Scout24, a strategic operator of real estate marketplaces in Germany and Austria (financial terms undisclosed), making IMMOunited a wholly owned subsidiary within Scout24's DACH portfolio. Headcount sits at 51-100 employees and no revenue figures are publicly disclosed.
