> Sell it now and you don't have to care what it's worth in 10 years. Unless you're already clearly a unicorn it's not particularly easy to find a buyer for your founder equity in a startup at the prices it might IPO at if things go well. Founders selling their own equity too early will also destroy morale and investor relations to the point where the company isn't likely to succeed anymore. Buyers realize this, and aren't going to hand you IPO prices for it.
