My first 5 years or so of solo bootstrapping were this. Then you learn that if you want to make money you have to prioritise the right things and not the fun things.
I'm at this stage. We have a good product with a solid architecture but only a few paying clients due to a complete lack of marketing. So I'm now doing the unfun things!
Because we have a few paying clients who seem pretty happy. We have upsold to some clients and have a couple more leads in the pipeline. We are good at stopping bots and we have managed to block most solvers, which puts us (temporarily) ahead of some very big players in the bot mitigation sector.
If we can do this with nearly zero marketing, it stands to reason that some well thought out marketing would probably work.
