More realistically, when you're an early stage startup, is that 10x means going from 0.1% to 1% conversion. That kind of change can be achieved by changing pricing models, changing product descriptions, changing the purchase flow, etc. And you'll notice it -- 1% means getting one buyer about every other day on 50 uniques; 0.1% means getting a buyer every three weeks. You won't need statistical validation to tell you that things have changed. But even "smaller" changes -- 10%, 20%, 30% -- are usually noticeable, even with a tiny stream of traffic. The point is, the kinds of winners that you need at an early stage are usually big enough to feel. Rarely do you get to the win in single-percentage increments.
