Koldur is a delivery infrastructure that developers install once and property managers maintain over time — open to any courier, no account or integration needed, keeping groceries at the right temperature until the resident picks them up.
No order to create, no PIN to generate. The compartment is fixed, securely assigned to one housing unit.
On the locker's display, just like a building intercom panel: no account, no app to install.
If it stays open for no reason, or closes earlier than expected, the courier still has three minutes to reopen it once.
A generic SMS signals the delivery. The resident opens their own compartment with a permanent personal code.
The locker can be installed in the building's perimeter wall or in its entrance hall.
The locker is sold once, the service continues over time.
Every locker is connected in real time to our monitoring center. We're not just promising a refrigerated cabinet: we guarantee someone notices if something stops working.
Many pickup systems fail because they ask every single retailer or courier to integrate with a platform before the service makes sense for anyone. Koldur starts from the opposite problem.
The locker works from day one because anyone can use it right away — no account, no software to install, no contract with us. The infrastructure belongs to the building. The maintenance and monitoring service is ours.
