Can someone explain to me why people return money to investors? Legal reasons? Altruistic reasons? Selfish reasons (maybe that keeping it would hurt their reputation and make them feel guilty)?
One reason is when the investors own > 50%, control the board, and decide to recoup 10 cents on their dollar. But I've known entrepreneurs who made the decision independently, feeling it was the right thing to do. And it is the right thing to do if the company has no other prospects or the team is falling apart. But even so, returning the balance just keeps some salt from the wound. It doesn't make anybody happy.
Why do you say that? If for moral/altruistic reasons, that doesn't make sense to me - if you have $x million, do you really think the best place to donate it would be to VCs? I don't know anyone who donates to VCs, so I assume the answer is no. (sorry if I come off as harsh, I don't mean to - I just don't know how else to put it)
