Made my first internet dollars with my 5th startup (oh, and I will not promote)

I've been building startups for more than 5 years. First one - the Telegram currency informer bot - had some real users & got some media coverage, but back then I knew nothing about monetization, how to work with clients, etc, so I just silently killed it (sad). Second one - eSports stats website - I was building this one with a friend of mine. We've had some outside financing, a small team of engineers, but no marketer. I gave this startup more than 2 years of my life, sacrificing everything and fighting depression at the same time (another story). We were able to make some money off it, but it was not a life-changing amount. We've tried to partner with affiliate guys, but it didn't work well - we've got no more than a couple of $ grans for all of us. Third startup - the self-hosting control panel on top of Docker Swarm (similar to Coolify/Caprover). It died together with my 9-5 when I was laid off with 21% of the workforce. Docker Swarm advertised as a stable tech turned out to be a nightmare. Took \~6 months from the very first line of code to my first potential users. Last one - a no-code directory builder. Started building this in late November, soft-launched in December, and now I have 140 signups and five directories on custom domains (didn't have a strict paywall to get my first users). Yesterday, one of the clients subscribed for a paid plan and started to make another directory. I will not promote, ofc.
