I love this. I also built a business like that[0]. It's super niche. I have maintained this small business for soon to be 13 years now. Most of what has worked has been maintaining great relationships with the few customers I have.
I think the most important thing for me have been offering amazing support. I always reply to all e-mails right away and make it my top priority giving them my best help.
Congratulations on your success, and best of luck going forward!
Thank you — and congrats to you as well, that’s an impressive run.
I completely agree: in a small, niche business, relationships and support matter far more than scale. Replying quickly, taking users seriously, and actually helping them goes a long way over many years. It’s probably one of the few real advantages solo developers have over larger teams.
13 years in a niche is no small achievement. Best of luck to you too, and thanks for sharing your experience — it’s always encouraging to hear similar stories.
Congratulations on your success, and best of luck going forward!
