Lots of photo, art, music and other hobby software is for purchase rather than subscription.
Off the top of my head Topaz Labs is a company that offers a suite of photo tools for purchase. They are aimed at both professionals and high end hobbyists.
I once bought Paste (a clipboard manager for Mac). However, they later switched to a subscription model, and I decided not to make a new purchase. Then Raycast, which is free, came out, and I stopped using Paste altogether.
I bought iExplorer which lets me sanely treat my iPhone like an external disk … and I bought Mountain Duck which lets me mount remote sftp as a disk in Finder …
Is any company making money in software without an enterprise revenue channel, aside from games? Do regular people “buy software” anymore?
