The Challenge
What we were up against
The Netherlands used-car market lacked a centralized platform where private sellers and dealers could transact transparently - sellers posted across fragmented classifieds, and dealers had no structured way to bid on inventory.
Listing a vehicle was a multi-step, manual process that discouraged casual sellers from completing their listings, resulting in high abandonment rates.
Buyer-seller communication was unstructured, with contact details shared before any commitment - leading to spam, low-quality leads, and trust issues on both sides.

Frequently asked questions about this project
Dealers browse listed vehicles and place bids directly on the platform. The system supports manual negotiation - sellers can accept, reject, or counter bids. Contact details are shared only after a bid is confirmed, preventing spam so both parties are serious. This creates a transparent, structured transaction flow.
