Superhuman PMF survey before growth spend
Ask active users how disappointed they would be without the product, then hold back growth spend until the answer shows real pull.
Why this can grow a startup
A waitlist, launch spike, or loud investor meeting can make weak pull look stronger than it is. Superhuman used the Sean Ellis question on recently active users and found only 22% would be very disappointed if the product disappeared. That gave the team a plain operating number instead of a mood. The growth lesson is uncomfortable but useful: before buying demand, measure whether the current users would fight to keep the product. If the answer is soft, spend the next sprint improving fit instead of filling a leaky bucket.
Company example
Superhuman surveyed users who had used the product at least twice in the prior two weeks, found a 22% very-disappointed score, and treated that as evidence it was not ready to scale demand.
