Ask HN: How might you find a co-founder who can code and will work hard?

I'd like to spend a couple months going all in on an idea. It'll need an app and I'm a developer so that's something I can make but I think having a second person would really help things along.

I don't know anyone who would be willing to help. I know getting the wrong co-founder can be worse than going it alone. I need someone who is as focused as I am and will work with my idea instead of offering peripheral ideas that will slow things down.

Any hope for me or should I go it alone?
