We have done this before, in e-mobility.
The team behind Parcelster built Fleetser, a marketplace for secondhand e-mobility fleets. Through Fleetser we have shipped more than 30,000 used vehicles to buyers worldwide.
That gave us a lot of experience in handling secondhand resale at scale. Parcel lockers are the same problem in a different shape: large fleets of hardware that one company retires and another can use.
