If you all have really read through the thread, all that you have said is already covered and that's not what I wanted to ask. How equity investment works, how to derive at a valuation, issuing of new shares etc. all are covered in this thread.
The question is really simple, which is what
@japancool has mentioned below.
I guessed you failed to understand the logic I am trying to explain.
If a Dragon is offered £50k for 50% of the company, and he is right to say that the business being valued at £100k, technically it means that the pitcher is offering £100k in value and the dragon is only offering £50k in value but both gets 50% of the business, you seriously think it is right?
However, if the £50k from the dragon
goes to the pitcher instead of the business, it means that both of them each contribute 50k to the business or in another words, the dragon is buying 50% of the business from the pitcher, then it make sense to have 50% equity each.
So it absolutely does matter if the money goes to the business or goes to the pitcher.
If it goes to the business, it is called
investment, business value increase to £150k (£100k initial value plus £50k new investment from the dragon.)
if it goes to the pitcher, it is called
buying of equity, business value still remains at £100k as the £50k from the dragon goes to the pitcher instead of the business.
