It's a false dichotomy. If someone's willing to pay $X for your company, you can do a secondary sale at ~.75*$X pre-money valuation to give key employees some liquidity. No, it's not the same, but it's still real money, and certainly alleviates the $100M->zero risk.<p>And if it's a real business whose value is based on, say, an EBITDA multiple, there's even less reason to sell, unless you think earnings are going to tank. (Presumably you will have significant visibility into the factors that determine your revenue and EBITDA growth, and what might cause those to change.)<p>But if you made a little photo-sharing app that earns no money, and someone wants to buy it for a truckload of money, sell. :)
