Frequently asked questions.
What is a housing cooperative?
Cooperatives (Genossenschaften) are non-profit landlords. Rents are cost-based, typically 20–40% below market. Tenants usually buy a modest share certificate, refunded when they move out.
Which cities do you cover?
Zürich, Winterthur, Zug, Luzern, Basel and St. Gallen, including surrounding municipalities. We add new regions regularly.
How fast are the alerts?
Our system checks continuously. Most alerts arrive within minutes of a listing going online.
Does the AI apply on my behalf?
No. It pre-fills forms and drafts letters. You always review and send yourself. You stay in control of every application.
How do I cancel?
In your account, in two clicks. Monthly plans end at the end of the billing month; the trial ends automatically if you don’t subscribe.
Which languages are supported?
The service, alerts and AI assistant are available in English, German, French and Italian.
