Ask HN: How do you build your founding team?

I am very excited, since this my first "AskHN" post on HackerNews. I am not sure if they ever get noticed, but I will give it a shot.

During the past six years, I co-founded 3 startups. They had all failed at the founding team level. So, I've decided to create a service to help startup founders and young entrepreneurs build their founding teams and get expert advices along the way.

I would like to get an objective opinion from other geeks/hackers/creators whether it's a problem you've experienced. I am very interested to know how startups build their founding teams right now and where do you find your dream co-founders? By the way, I need one also!

You can find more info about my startup at http://flou.io

Thank you and have a great day!
