Carton Vault is developed by a group of passionate IT professional who grown up in Hong Kong. We started our business as a system integrators and IT consultants. We started to work on Carton Vault because of the demand from our customers.

We are committed to create a solution that address one of the issues we all face: too many data nowadays, we need a place to back them up and forget about them. However, we need a way to retrieve them when I need them.
