The Whicher is a new way to be lean — it's like A/B testing combined with a market research survey. A/B testing is fantastic, but have you ever found yourself trying to devise a test where you're not sure what to measure? Maybe because you don't have enough traffic to wait for 100 sales per variation, or maybe you're not sure what to conclude at the end of the test? The Whicher takes your variations and ranks them by quality, using only a few hundred participants; no need to wait for conversions. Oh yeah, and you can have dozens of variations now instead of just a few. In fact, it works best with 5 or more!
