What are your thoughts on various business models?

The traditional "sell once, offer paid upgrades" seems to be better suited for apps with a stable feature set, where you can take a year or two to produce the next major version. However, a more iterative approach to development doesn't work with this model very well.

The recently popular switch to subscriptions (Adobe, Office, 1Password, Jetbrains, YNAB, etc), while obviously every developer's wet dream, may not sit very well with customers, at least if there's no obvious service being offered (like e.g. Dropbox).

I think it depends on your software and your price point. You're never going to sell a $20 app as SAAS without a service component. 1Password probably didn't have a long term path forward selling a stand-alone $65 password manager. Certainly something worth thinking about from the beginning. If you can have a desktop app that integrates with a service and have SAAS pricing you will be truly living the dream.

Interesting. What exactly do you mean 'desktop app that integrates with a service'? Any examples?
