As counter-intuitive as it sounds, I hypothesize that an early startup guided primarily by gut decisions from a strong strategic vision will be more cohesive and deliver a stronger offering than a startup created from a random walk of data-driven decisions. Though I don’t have the data to back up my claim.
Nor do I, but I feel the same. Don’t waste time with A/B testing until a) it actually matters and b) you have the requisite sample size. Until then, stick to your (data-driven, as in qualitative) guts.
