> Yes and they get a salary for this like they would at any other company.
You've obviously never worked as an early employee at a startup. Pay is never equal or even close to what you'd get at typical big company. Typically that's explained to be because you get equity -- often a pitifully small set of options which if you do the math you'd realize probably wouldn't equal the difference in salary over 4-5 years in anything but the most wildly optimistic scenarios. (The OP's employees' windfall is probably break-even with their opportunity costs.)
