Have you ever found a partner who complements your skills?

Here is the story:

For past few months I've been designing & developing web apps. The thing is, I'm not good at design and I simply don't like it. It's kinda hard to be really good at design and development at the same time, so my apps are not that good looking.

I guess it would be a win-win situation if I could find someone with design skills, because I can code.

If you are developer, do you design your apps or your partner does it for you? If answer is yes, how did you meet that guy?
