Three questions that get you product-market fit quickly.
In this short instructional video, Kit Barber explains why early‑stage founders often mistake sign‑ups for proof of product‑market fit and introduces a more reliable method called the Sean Ellis Test. He outlines three survey questions to ask existing users: (1) How would you feel if you could no longer use the product? (options: very upset, a little upset, not upset) – with a benchmark that fewer than 40% “very upset” signals insufficient fit; (2) What is the main benefit you get from the product? – to surface the actual value users derive; (3) Who do you think would like this product the most? – to identify the true target audience. Barber then describes how to split respondents into a “very upset” core group and a “a little upset” group, use the core group’s stated benefits to double‑down on features, and use the second group’s wishes to add improvements that can convert them into core fans. He claims this approach can raise the proportion of happy users from 30% to 50%, turning a marginally viable business into one ready to scale. The video’s tone is conversational and instructional, urging founders to replace guesswork with data‑driven validation.
