3.4 Testing Your Idea

Before writing code or building prototypes, test your idea informally to see if people care. There are several simple techniques:

Early Validation Tests: Run small experiments that mirror real use. For instance, create a simple landing page that describes your product and has a “Sign Up” or “Pre-Order” button. Run a small ad campaign or email blast to drive traffic to it. If people click through or leave their email, it’s evidence of interest. In Lean terms, you’re testing the “value hypothesis” by seeing if customers take the desired action. Failory’s validation framework suggests even setting a “pre-selling goal”: define how many signups or dummy purchases would prove demand, then see if you reach it. For example, Dropbox’s founder posted a demo video and grew their waiting list from 5,000 to 75,000 users overnight, while Buffer started with a two-page website to test if anyone would sign.
