What's the best job choice for a non-technical person at a startup?

Just wondering what your opinion of a great and rewarding role is at a startup. My ambition is to launch my own company when the time is right, but in the meantime I would like to continue learning and meeting like-minded people. I believe my strengths are in creative strategy, growth, and doing what it takes to help startups grow. I would like to hear your thoughts, especially if you have gone through the same challenges:)
