Do I understand it correctly, that the DPO did not put any money into the company?

If so, it was a pure "Here, we built something valuable. You can have it now if you pay enough" kind of deal with the investors?

Somehow this type of transaction always makes me feel a bit strange about the value of a company. Not sure if this is a rational thing or not. I think "Why did they bring it to the market at all?". What is the rationale for taking a profitable company that does not need additional funding public?
