I started a company that built, I believe, the most advanced no-code data automation desktop application (https://easymorph.com). It's entirely bootstrapped, profitable and pays salaries to 10+ people (and we keep hiring).

Many our customers specifically looked for an on-prem solution as they don't want to deal with SaaS and its privacy issues and use-based pricing. With an on-prem tool like ours they get unlimited runs, unlimited data volumes, unlimited use for a reasonable fixed price.

I believe SaaS is overhyped and in a few years the trend will change toward on-prem SaaS-like apps and platforms.
