Mietradar

On the Swiss rental market, hours decide who gets the apartment. Mietradar continuously scans the market, captures new listings within minutes and delivers them by email alert — including cooperative housing that never appears on the big portals.

Automated Operation

Starting Point

On Switzerland's tight rental market, hours matter. Portal newsletters arrive with a delay, and affordable cooperative apartments never even show up there.

Solution

A web app with continuous data capture, search by location, radius, price, rooms and size, an interactive map, personalized email alerts and a dedicated cooperative radar that automatically monitors the vacancy pages of 28 housing cooperatives.

Result

New listings are captured every 10 minutes and reach subscribers before the portal newsletters go out. Every listing links straight to the original source — apply as usual, just earlier.

Under the Hood

Data engineering, always on

  • Automated data capture: a worker process syncs the listing inventory around the clock and detects new offers within minutes.
  • AI-powered cooperative monitoring: vacancy pages without a common format are read and structured using a language model.
  • Map search: the result list follows the map — pan, zoom and filter without reloading.
  • Search alerts: save a search profile and receive new matches by email automatically — with confirmation email and one-click unsubscribe.
