IMMOBILIEN.CH GROUP — A new Swiss real estate platform.

Two Brands · One Platform

Two addresses, one Swiss system.

The platform speaks to two worlds — consumers and professionals. Each world has its own brand, its own tone, its own domain. In the background, a single Swiss infrastructure.

Vision · Four Pillars

A Swiss platform that serves the industry — not the advertising.

We are building the infrastructure on which the next decade of the Swiss real estate market will run: transparent, data-driven and independent of foreign advertising portals.

Infrastructure, not advertising. Tools, not listing slots.

Dual-Brand Architecture

Two complementary brands — IMMOBILIEN.CH as the consumer entry point, LIEGENSCHAFTEN.CH for professional actors. One shared infrastructure, two curated experiences.

Consumer + Professional

Broker Network & CRM

Swiss brokers receive their own tools instead of just listing slots: valuation, pipeline, client communication and marketing in one place — built for the reality of the Swiss market.

Tools, not ads

AI-Powered Valuation

Models that understand Swiss micro-markets — from Lake Geneva to the Engadin. Valuation, comparison and market analysis that owners and brokers can actually use.

Swiss-trained Models

Data Sovereignty

Swiss data, Swiss hosting, Swiss governance. A platform in Swiss private ownership, not dependent on international groups or investment vehicles.

Sovereign by Design

Market context · In figures

Why now. Why Switzerland. Visible in figures.

The Market Intelligence Terminal shows the Swiss real-estate market from four angles: four core KPIs with 5-year sparklines quantify transaction volume, digitalisation rate and broker landscape. The canton heatmap colours all 26 cantons by transaction volume — clicking a canton filters the other views. The trend chart next to it shows residential and commercial yields as well as the digitalisation rate 2020–2028; a time slider moves the cursor through the years. The Sankey diagram visualises the market shares of the existing Swiss portals and marks the target position IMMOBILIEN.CH Q3 2026 as a pulsing anchor. The TAM–SAM–SOM cascade below breaks down the entire market potential into three expandable layers. Click cantons, drag the time slider, open the cascade tiles — every action updates all views live.

Principles

Our principles.

Six guiding principles that hold every decision about the platform — regardless of market phase or growth.

Swiss ownership

The platform stays in Swiss hands. Ownership and control remain domestic for the long term.

Long-term perspective

We build for decades, not quarters. Stability comes before short-term acceleration.

Data sovereignty

Data from Swiss owners stays in Switzerland and under Swiss law.

Industry partnership

The platform is built in dialogue with brokers, property managers and owners — not against them.

Quality before growth

We grow when quality holds — not the other way around.

Tools, not advertising

Professionals get working tools, not listing slots. Consumers find clarity, not click-bait.

Platform Architecture

Five pillars. One integrated system.

Not five separate products — one integrated Swiss real-estate infrastructure.

Launch

The roadmap is a planning guide and not a contractual commitment. Sequence and pace will be finalised jointly with strategic partners.

Strategic Partner Programme

We build with the industry, not against it.

Unlike purely financial platform investors, IMMOBILIEN.CH GROUP brings in qualified Swiss real-estate partners as strategic shareholders — brokers, property managers, industry experts and Swiss family offices with real-estate experience.

Co-Build

With the industry, not over it

Swiss brokers, property managers and industry experts become shareholders. Every strategic partner automatically becomes a structural defender of the platform.

Industry Expertise

Operational depth as equity

We are not looking for passive cheques — we are looking for partners who understand Swiss real-estate workflows and help shape the platform.

Swiss Anchoring

Swiss capital, Swiss law

Private placement under Swiss law — exclusively for qualified investors pursuant to Art. 4 FinSA. No public offering.

Roadmap to 2028

Eight quarters. A clear path to public launch.

Detailed quarterly plan. Investor-grade due diligence pack available on request.

Founder & Background

Antoine Parrella Aliberti

1986 Teenage inventor · at 15 co-developer of a commercially released Amiga arcade game · at 17 inventor of an SMD sound sampler for Amiga 1000/2000 — 500 hand-built units

1993 Swiss internet pioneer · Co-founder Vadian.Net AG · owner immobilien.ch & liegenschaften.ch

I registered these domains in 1993 because I already knew then what the internet would mean for the Swiss real estate market. Now is the time to bring them onto their own platform — so that seekers and owners finally have a true Swiss alternative, on Swiss soil, with Swiss values.

Company History

A Swiss internet story. In three chapters.

From domain registration in 1993 through the pioneer decade to the platform’s return in 2026 — a story continuously enriched with historical materials and new milestones.

Chapter I · Archive

1993 · The birth of Switzerland’s real-estate domains

Registration of immobilien.ch and liegenschaften.ch — when hardly anyone thought of a Swiss real-estate market on the internet. Domains held in founder ownership ever since.

Chapter II · Pioneer Decade

1995–2010 · Co-building Switzerland’s internet infrastructure

In 1995 Vadian.Net AG launches immobilien.ch as the 1st online marketplace for Swiss real estate. Later a data interface to ImmoScout24 (API integration before the API era), followed by a multi-year licensing agreement — the domain remains in private ownership.

Chapter III · Platform

2026–2028 · The platform’s return

Founding Partner Programme, Anchor Phase, Public Launch: three years of controlled build-up under own ownership. Every milestone documented — transparently and with Swiss precision.
