Marginal User Framework

Overview

A method for identifying high-leverage product improvements by focusing on the user "on the cusp" of conversion or the "worst-case scenario" user. Solving for the user with the most friction often resolves hidden issues for everyone.

Core principle: If you solve for the hardest user, you unlock growth for everyone.

• Data funnels not revealing friction points
• Growth has plateaued unexpectedly
