At work, we use Paperspace quite a bit for Desktop-as-a-Service in order to teach distance learning and in-person classes. We like not having to rely on our users having beefy(ish) laptops or being able to install software on them. The killer paperspace features for us, in no particular order, are:

1. Private networks -> keep classes isolated 2. Shared drives -> mount read-only class data 3. Create machine images -> build out the 'base' class image and spawn new instances from it 4. An API for spinning up and down

It seems like you are positioning yourselves as more for individuals and less for companies. It's not clear fo me from the landing page, but does Vagon require you download and install a client? Or is there a browser-only option? If we were to spin up, say 35 VMs, and then destroyed them a week later, is that $7.99/month charged for each machine or just once? Is it pro-rated if you don't use the whole month?
