Product-Market Fit

Definition

Product-market fit is the state where a product addresses a meaningful user need strongly enough that customers adopt it, use it, and recommend or pay for it with real conviction. It is not just that people say the idea sounds good; it is that the product becomes a compelling option for getting an important job done.


Core Ideas

Need Before Feature

The source notes emphasize that users “hire” products to do a job. Fit comes from solving the right job, not from piling on more features.

Trigger Situations

Fit is often linked to specific circumstances that push users to act. Understanding those trigger events is more predictive than relying only on demographic descriptions.

Early Discovery

Founders often find fit by:

  • talking directly to users
  • manually recruiting early adopters
  • watching real behavior rather than collecting vague opinions
  • iterating quickly based on concrete feedback

False Signals

The notes warn against mistaking:

  • polite interest
  • feature requests without real urgency
  • launch attention without retention for actual product-market fit.
