Already exists (in SF at least). Roost, StowThat.

AirBnB existed before AirBnB as well. People just called it Homeaway or VRBO. AirBnB did a few key things much better. I think there's the same opportunity in self-storage (although not sure what makes this model finally take off).

Makespace is doing this, at least in NYC. They have all my stuff that I'm almost ready to get rid of.

I use it too. Has been super convenient while traveling/moving.

Yea, I think this a really good idea.

I've also had the idea of an AirBnB for 'toys' (i.e. sports equipment, motorcycles, bikes, instruments, etc).

There is already RelayRides for cars, and qraft is probably the closest existing site to my idea, but I think it could be executed much better than qraft.

Here's a list of self-storage startups https://angel.co/self-storage

In Seattle, Stash (https://angel.co/stash-4) is doing this.

I remember someone in the philly startup scene who was trying this a couple years ago. I forget what name they had.

Someone should do it; i like it
