Generating money for shares in your businesses, I understand this... so in this example I open a bakery, needing 100,000. I have 10,000 and get 9 friends to each give me 10,000 for 10% of the business.

Whatever profit I make, each friend will get 10% each? And is the 10,000 they have bought 10% of the business with a one off payment?

1 year later, the business is worth £1,000,000; each 10% share is now worth 100,000 if I wanted to buy 10% back of someone I need to pay them 100,000 (they have made £90,000)
