Grundheim is the data-driven platform for Swiss property buyers. Upload sales documents — listings, plans, sales brochures — and receive a structured assessment in under 10 minutes, including risk analysis, location check, price estimate and personal fit check. All data remains in Switzerland and is end-to-end encrypted. No sign-up required. First assessment free.
A sound valuation reveals hidden risks before the viewing — noise exposure, flooding, contaminated sites, public transport accessibility, neighbourhood data. You save time, avoid costly mistakes and deal with sellers based on facts. Instead of reading average estate agent sales copy, you see objective data from the Federal Statistical Office, the Federal Office for Spatial Development and cantonal GIS portals — tailored directly to the property.
Three steps: upload sales brochures, listings or estate agent documents (PDF, scanned images or text). Our AI-powered platform automatically extracts the address, living area, number of rooms, year of construction and pricing details. In under 10 minutes, you receive a structured assessment with risk analysis, location assessment and a price estimate compared with similar properties in the region.
We combine more than 30 data sources: municipal Steuerfuss, noise exposure (road, rail, air traffic), flood and contaminated site risks, public transport quality class, schools and hospitals by commuting time, population structure, vacancy rates, historical price trends and residential construction activity. All figures come from official sources — ESTV, BFS, ARE, BAFU — and are updated daily.
First-time buyers who want to make informed decisions before tying up hundreds of thousands of francs in equity. Commuters weighing up several places to live. Investors assessing regional market trends. Families comparing schools, noise exposure and quality of life. B2B clients — insurers, banks, property portals — also use our data via API.
The first assessment is free. Additional assessments can be purchased via credit packages from CHF 19 per assessment — depending on the package selected. There is no subscription, no hidden fees and no long-term commitment. You only pay when you actually need an assessment.
Estate agents sell property — we analyse it. Our business model does not depend on a successful sale, but on the quality of our analysis. You receive objective data without sales pressure. As a complement to an estate agent viewing, Grundheim provides the data basis for an informed purchase decision.
