Taking money off the table

I believe the complete opposite. If someone is willing to buy your business, no matter the amount, it’s because it’s worth MUCH more than what they’re paying. It’s illogical for them to pay less than its real value. It’s even illogical to think they’d pay exactly what it’s worth. Why would somebody bother buying a company if they were only going to break even?

Almost all startups go to zero, meaning every cent what VCs paid for stock, at any price, did not end up being worth more than they paid.

Sure, what I'm getting at is that in your hands, or in the buyer's, the value can go to zero or multiply. If they buy, it's because they assess that the chances of it multiplying are greater than it going to zero. Why sell in that case?
