PSA to folks who answered this: if you have a profitable side project, double down and try making it into something more than a side-project.

If you've built something that is actually collecting revenue, you're already ahead of a huge number of folks out there, and you can likely build it into something that can at the very least make you live comfortably, if not much more.

It depends on how you define "profit"... I have invested $10 for a domain, and if you exclude my development time, I'm making a profit on UnitPrice.org! [0] It's a website that analyzes specific categories of products on Amazon and calculates the best per-unit price. Lego, diapers, toilet paper, K-cups, etc. Obviously your own time is worth something, but it's fun, and despite barely getting any affiliate fees, it's enough to cover the domain name cost! I also use the website personally, so I've saved money on purchases too.

No longer a side project since I made the switch to work on it full time, but my stock option scanner SaaS [0] is profitable and my main source of income.

Webase [1] is a no-code platform for building CRUD apps without writing early code. It has found a niche in being able to dynamically generate PDFs based off of forms combined with business documents for things like Real Estate contracts.

Website still needs to communicate the value more, but it is a fun project to keep improving.

Started off as an email a link to get paid with Stripe for art dealers but now has a focus on the due diligence and was well-timed with some EU money laundering regulations.

Growing revenue 150% month on month and will likely have to become my main source of income soon.
