How to arrange all this with an investor?

Question

Startups

There is a man with N money.
I have an idea that he is ready to invest in.
But so far neither I nor he has a clear vision of how to do it all.
I would like that in the end I could buy the product from him (he will shoot, that's for sure). But it’s not entirely clear, for example, this:
1 how to register as a percentage who owns what
2 at what stage in the end it is necessary for me to be able to redeem (shares?), Or vice versa - so that he earns his interest and sells his part to me.
3 Are there any model contracts for this, or an explanation on the fingers of how such relationships work? Well, for example, how and what is usually done step by step in this case, how is it formalized? How is my investment of time and effort into the development of the project, not only as a techie, but also as a product/project manager?
Help me figure it out plz.

Answer 1

Try a convertible loan rather than an investment or a loan.
Quote

The investor says the company is worth $1M, the founders that $2M. It all comes down to banal trading, and this can last for weeks. There is no tool for determining the value of companies at an early stage, and it is unlikely that there will be one.
To avoid this situation, you can make investments in the form of a convertible loan. In this case, the value of the company will be determined by the investor in the next round - and usually the named figure suits both parties. And to compensate for the risks of an earlier investor - to create advantages for him over investors of other stages - various conditions are used. Among the large variety of variations, the most important are Maturity Date, Discount and Valuation Cap.

Answer 2

it is unlikely to force an investor to sell his share later according to the law, if he himself does not want to, as he investigated this issue in the year 2011, I do not think that much has changed in this matter.
another thing is that if he wants to sell himself, you can get the privilege of an initial buyout
, these are not standard contracts, you will not find examples

Answer 3

Agreement.
Not typical. Why do you expect the contract to be standard?????
In the contract, just paint all the nuances.

Answer 4

Why not take money from him on credit, and not launch it into your project, if you are sure of success, of course?

Answer 5

Write a contract and attach detailed terms of reference to it
