I only have an idea, am I too early?

Not at all. An idea is all it takes. I gladly help you to turn that idea into a business.

Can you tell me if idea is good enough?

What kind of founders do you work with?

Anyone who wants to learn and grow. You bring the motivation and commitment, I bring the rest.
