Before you start, make sure you look at what you're going to need to make your business a success and look at what you can bring to the table and what you need.

A lot of start-ups struggle to get off their feet because the co-founders share a vision and a background which makes them great for bouncing ideas off one another, but then they get stuck at the execution stage where they need a skill set they don't have and can't afford to hire.

If, for example, you're an expert at travel and history, than you probably want to partner with an expert on marketing and technology because they'll be able to help you execute on your vision.

If you rock at marketing, but you're not as strong in logistics, you probably want someone with a lot of experience in travel logistics.

Define the partner who's going to help you achieve your goals, and then make sure that you go through a very thorough vetting process to make sure that you find the right partner for you.

Good luck
