Ehsan's Insight

A/B testing is treated as a growth best practice and mostly produces garbage results. The problem is statistical: 80% of A/B tests at startups do not have enough traffic for statistical significance. Running a test with 500 visitors per variant and declaring a winner at 85% confidence is not "data-driven" — it is random with extra steps. The minimum viable A/B test requires roughly 3,800 visitors per variant to detect a 5% relative improvement at 95% confidence. If you do not have that volume, use qualitative research (user interviews, session recordings) instead of pretending you have quantitative evidence. Better to make informed decisions than to make random decisions dressed up as data.
