starting a business to someone is not a bad idea but the first question you ask yourself is whether you trust the person or not, because trust keep business going.On the contrary the usual issue in a partnership is the leadership - who will be the boss. It is good if the partnership is one financial partner and one industrial partner. At least the boss is clearly defined. But if everything is equal in capitalization and in time rendered in business then the boss thing will be a big issue later on.
