Ask HN: meetup would be the best way to find cofounder?

Well I'm still struggling to find true cofounder for my new project. I worked on prototype and now started building frontend, but so many people I talked to were so busy to join it, even if they'd love to. But I'm not able to attend many meetups right now because I'm in south korea yet for some reasons.

In this case, still meetup would be the best way to find dudes? I'm thinking about submitting YC Winter season with prototype and probably I can't attend meetups for a month and half, maybe.

Wanna hear HN-ers' thoughts :)
