A wetransfer-style model is popular for contractors and small businesses who often need to share files with clients and don't want to run their own file hosting service.
I think a few small businesses I worked with in the past paid something like $10/mo for 250gb of file sharing w/ links that worked indefinitely + custom branding on the upload/download pages they created.
Would you want to pay for a single link? For example, pay $2 to make a particular link last for 30 days?
Or, would you want to pay as a subscription? For example, pay $10 per month for 2TB of storage to use however you want?
