A question for Patrick, or for anyone else with experience implementing A/B testing from the early stages of a service/product:
When and where do you start? If you start too early, you don't have enough traffic to be statistically significant.
In the article, Patrick said that he started with the trial signup form in his 3rd year.
Most of the advice on A/B testing that I've found is understandably aimed at people with existing business/products that can massively benefit from it. Does anyone have any more material about how to get started from the early stages?
