How to Check Demand Before Building a Product

To check demand before building, gather public signals that show people are actively searching for, discussing, or paying for solutions to the problem you want to solve. The less guesswork in your decision, the better your chances of building something people want.

This guide covers the fastest ways to check demand before you commit to building a product or service.
