why would businesses pay for something that was always free?
selling bottom to top is terrible strategy that rarely works (been there, done that)
you should instead market it to decision-makers who actually have a say what services the business purchases or not
developers have no say in business and have no access to credit cards
basically if you want to sell a terminal app, don't sell a terminal app, instead sell your "productivity platform" and terminal is just needed to "access productivity benefits"
