Nick Perry says founders waste months building products nobody wants. The only real validation is a paying customer. Sell first, build second, or risk wasting everything on features nobody will pay for.
Most founders build for months, then no one buys. One of the biggest mistakes entrepreneurs make: building something before they've confirmed anyone actually wants it. Most founders spend months creating a product only to discover nobody's willing to pay for it. Do the opposite. Find a customer first. Sell before you build. Sell the solution before you build it, then figure out how to deliver. Why? Because when someone pulls out their credit card, they're giving you the only validation that matters. Not compliments, not likes, money. A paying customer tells you more in 5 minutes than months of guessing ever will. Build what people pay for, not what you hope they'll want. That's how you create a business people actually buy from. Before you build another feature, go sell the promise first.
