Why validate an idea before building?

Building on a hunch is the most expensive way to learn a problem isn't real. Validating against 1M+ existing complaints lets you confirm a problem is frequent, severe, and underserved before you write any code.

How does data-driven validation work?

Instead of surveys or guesses, you look at what people already complain about at scale across Reddit, G2, Capterra, and the app stores. Recurring, severe complaints about underserved problems are the strongest signal that people will pay for a fix.

Where does Linkeddit fit in?

Linkeddit is the other half of the founder research stack: once you know what to build, it finds the people on Reddit actively raising that problem so you can reach your first customers.
