Scam artist. In Switzerland there is one company selling your property for a fixed price, but people are afraid to use them, thinking they have no interest to sell your property at the highest price.

Interesting, we have a failing company here called Purple Bricks who offer list your house on the main property portals and will charge you a small fixed price for other services like viewings.
Almost nobody uses them because they are perceived to not be as likely to attain a sale as traditional agents.
