Yes, a business can be successful without growth.
Can a startup? No.
Can a company? Not always but in many circumstances, yes.
If you want to run a business and just keep it at $5MM ARR and pay yourself and some people, by all means!
Nothing at all says success = growth.
However, there are many things dependent on growth. Make sure you’re considering the right context, getting appropriate feedback, and appreciating that whenever anything is said with certainty, it’s probably wrong.
