## Resource

How do you determine if your idea is truly worth pursuing? In this week’s episode, we dive into a practical framework that breaks down the evaluation process into four critical components: the pain point, the market size, the defensibility of your product, and how you plan to monetize and scale. Whether you're just brainstorming or already building, these criteria will help you gut-check your concept and avoid wasting time on ideas that aren’t big - or painful - enough. We also discuss market sizing (TAM/SAM/SOM), moats, and why competitive advantage isn’t always what it seems. This is a must-listen for any founder looking to go from “cool idea” to real business.
