That's really impressive!
I'd say I'm on the same way :)
My projects:
1)
https://talk-talk.me
(pretty old thing, when Slack didn't have its own voice messaging)
2)
https://browsercloud.io - API for cloud Puppeteer / Playwright running, web scraping API.
The product is B2B mostly, I have some paid customers, but stucked with further marketing
3)
https://flipper-ai.com/ - B2C, decided to catch some hype with chatGPT and made Chrome extension, but it's a big competition where everybody has the same API thus it's a real UX war who will make an app much better / prettier
