At the recent StartAtlanta event, I met the founder of TripLingo and we went from concept to prototype in a weekend. We ended up "winning" that event, and have kept moving forward. The great thing about StartAtlanta or similar events is that you get to feel everyone out and decide if you want to pursue the idea, and conversely, keep team members moving forward.
It helped greatly that the TripLingo founder and "business dude", Jesse Maddox, was well prepared. He had mockups of the app, spreadsheets with sample data, and a business plan. He had put in 6 months of effort researching, was tech savvy (though not a programmer), and was organized. The point here is that if you're the non-tech-co-founder, putting effort into the things I just mentioned show, and you'll have no problem attracting top geeks to work on your startup.<p>-p
