The startup plans to add warehouses in the outskirts of Taipei.
Started in 2015, Boxful has expanded to four cities, Taipei, New Taipei, Keelung and Taoyuan in Taiwan.
Four months ago, Boxful raised $18 million from investors in the property sector including Shimao Property Holding Limited, Shui On Land Limited and Nan Fung Group.
Prior to that, in June 2015, Boxful raised a $6.6 million Series A funding. It followed it up with the acquisition of Go N Live, a Hong Kong storage firm, in the same year.
The mini-storage market has became an option for customers in Taiwan and Hong Kong where living spaces are congested with high property prices.
In the storage market, Boxful competes with other storage startups like Spacebox, Klosit, StuffGenie and Go N Live.
