Webzenz Switzerland developed Piramida.ch, a Swiss classifieds marketplace in German, French, Italian and English with regional search, messaging, Stripe and AWS.
Overview
Piramida.ch is a custom-built classifieds marketplace for Switzerland. Users create listings in German, French, Italian or English, search for offers by region, message sellers directly and can promote listings for a fee.
Webzenz Switzerland handled the complete delivery, including the servers on AWS. A flexible structure for categories, attributes and fields makes it possible to add new sections without programming.
Starting point
A marketplace for multilingual Switzerland has to handle listings, search and administration in four languages and work regionally by canton and town. At the same time, the platform needed to generate revenue through memberships and packages and be easy to find in search engines.

Four languages

Dashboards with key figures and management of users, listings, categories, attributes, memberships, payments and pages, including CSV export.
