I have seen angel investors / venture capitalists on shows like 'Shark Tank' who make claims about how they will benefit the businesses the invest in, more than just that investment.
They make claims like "I will add some value to the product", "I must do a lot of work for this business that you don't know/understand", "It takes a lot of my time and drains a lot of my energy", "It is a good fit for me and I know what to do", etc.
Do they want to make investments in these businesses, or they would like to engage into the business? If they do like to engage, why wouldn't they just do all the jobs with their own teams and earn more money?
