Threadiverse communities similar to Reddit's "SomebodyMakeThis" subreddit?

The title says it all. Basically, a truly free alternative to r/SomebodyMakeThis that is not on Reddit (or should I say Reshit? 😎), to basically connect people who have time, and/or money, and/or skills (but no ideas of what to do with them) with people who have ideas and perhaps theoretical knowledge (but not time, and/or money, and/or skills).

I'm very good (I think) at programming theory, as well as broader computer science theory... But in practice I can barely make a (ugly and clunky) "Hello world" program in Python, and I have some pretty interesting and good (or at least I think so) ideas about software that would be really good if made (apps/programs, extensions, plugins and scripts for existing software, frameworks, libraries, algorithms, etc.).

Is there something like this on the Threadiverse? And if so, could you give me the abbreviated identifiers/handles of some of those communities? That is, your !community@instance.tld. I thank you in advance.
