Building a product nobody wants is the most common and most expensive mistake in entrepreneurship.
Months of work. Real money spent. A launch nobody shows up for.
The good news: it's almost entirely preventable.
Validation doesn't mean getting people to say they like your idea. It means proving that someone will pay for it before you build the full version.
There's a massive difference between:
Before you write a line of code or manufacture a single unit, work through these steps:
Step 1: Define the problem precisely Can you describe the problem in one sentence? Can you name three people who have this problem right now? If you can't, you don't know the problem well enough.
Step 2: Talk to 10 people who have the problem Not to pitch them. To listen. Ask about their current solution, what frustrates them about it, and what they've tried. You're looking for patterns.
Step 3: Build the minimum version A landing page. A mockup. A manual process. Something that demonstrates the solution without requiring full development.
Step 4: Ask for money Pre-sell it. Offer an early discount. Take a deposit. If they won't pay before the product exists, they probably won't pay after.
Expect to be wrong about something. Maybe the problem is real but your solution isn't the right one. Maybe the solution is right but you're targeting the wrong customer.
That's fine. Adjust before you build. The goal of validation isn't to confirm your hypothesis — it's to find out the truth as fast and as cheaply as possible.
Six months of development. Inventory that doesn't sell. A service nobody renews.
Validation takes two to four weeks if you do it aggressively. It could save you six months of your life.
Do it first.
