### Product-Market Fit

Product Management
The degree to which a product satisfies a strong market demand, typically measured by customer satisfaction, retention, and organic growth.

Product-market fit is the holy grail of startup success. It occurs when your product solves a real problem for a large enough market that customers are actively seeking it out and willing to pay for it. Marc Andreessen famously said that product-market fit is the only thing that matters for startups.

### User Story

Product Management
A short, simple description of a feature from the user's perspective, typically following the format "As a [user type], I want [goal] so that [benefit]."

User stories are the building blocks of agile development. They capture requirements in a user-centric format that focuses on the value delivered rather than technical implementation details. Good user stories are independent, negotiable, valuable, estimable, small, and testable (INVEST).
