I ask because I don't see any reason that paid open source contributions wouldn't be as good as non-paid open source contributions when it comes to gaining/demonstrating certain types of dev experience (though ofc without the benefit of also potentially showing character traits related to being willing to donate time for free), so I'm struggling to imagine you wrote that comment actually hoping for any answer other than "great thanks for telling us about the thing you founded". Apologies if I've incorrectly jumped to a bad faith interpretation - if so, you could maybe be more clear in explaining what your question actually is; if my assumption was correct then I'd suggest thinking twice before using low-effort and low-value comments for promotion, since people (and in particular people who would be valuable to have using your service) are liable to be put off by any product/company/service that spams in such a way.
