MakeSpace is a New York-based company being hailed as the Dropbox of physical storage and has now raised more than $10 million in funding.

According to Fast Company, paying $25 a month will get four big, empty bins delivered to the doorstep. Fill those with all the junk you don't need now, and then MakeSpace will pick them up and store them at their secure storage location. You can visually catalog contents by taking photos, and when you want a bin back, just click it on the website or app and it will be quickly redelivered.
