Startup Cubby is bringing a tech mindset to the wild world of self-storage—and just raised a $63 million Series A

Wild things happen in the self-storage business.

In 2023, Matt Engfer was at back-to-back lien auctions in Texas. At auctions like this, bidders buy abandoned units with no idea what’s inside, gambling on mysteries. 

So, the opening of a unit can get dramatic. The lock comes off, the door curls up, and everyone inhales. And on this particular Texas day, that first unit was an out-of-left field treasure trove, filled with artwork worth tens of thousands of dollars. The second unit was even more memorable.
