well I found cofounder thru HN. Finding someone who interested in- could happen someday, but I think getting meaningful feedbacks about it and improving idea by building prototype is the right way I think. And if you already shared it but no response, then you should practice how to describe your idea looks interesting.

I read many HN posts to share ideas and trying to get response, but most of them are too long and too detailed. Of course some ideas require long descriptions, but most of them, No. I spent so many times to describe my project sounds cool and interesting. 2 sentences that just describe what will happen next with idea > 50 sentences with description of all features you're thinking.
