Problem with these small things is that they don't scale thus can't exit. It means you will have to just milk them for profit over many years and they never get big. If a SaaS has a 6x revenue multiple as it does now, it doesn't mean that you can sell a thing that fetches 5K per month for 400K. You can only keep milking it. A thing that fetches 5M per month, for 400M? sure, but it will never get there.
