Test & Fail Early: Avoid Costly Business Mistakes

Dr. Niklas Richter · 2026-04-28

### Why Most Entrepreneurs Waste Time (and Money) You've got a great idea. You spend months perfecting it. You launch it with a big splash. And then... nothing. Your customers don't care. Your product doesn't solve their real problem. You're left with a pile of invoices and a bruised ego. Flip Keijzer knows this story all too well. He's an entrepreneur and business consultant at HKB who built a company from zero to over $11 million in revenue. His secret? He doesn't wait for perfection. He tests early, fails fast, and learns what actually works. ### The Lean Startup Method: Build, Measure, Learn The whole concept of "test and fail early" comes from the Lean Startup approach. It's simple: build a tiny version of your idea, measure how people react, and learn from what happens. Then do it again, and again, until you get it right. Most entrepreneurs get this backwards. They build for months, launch, cross their fingers, and panic when things don't work. Flip says that's like driving with your eyes closed. You're moving, but you have no idea where you're going.  ### Why We Hold On Too Long Here's the thing: we all get attached to our ideas. They're like our babies. We've invested time, money, and ego into them. So when the market tells us they're not working, we double down instead of pivoting. Flip points out that fear plays a huge role here. Fear of failure. Fear of looking stupid. Fear of losing the money you've already spent. But here's the truth: the money you've already spent is gone. It's a sunk cost. The only question that matters is: will this work tomorrow? ### How to Test Without Going Broke You don't need a million-dollar budget to test your ideas. Flip suggests these low-cost methods: - **Create a landing page** with a simple description of your product. See if people click "buy now." - **Run a small ad campaign** on social media. Spend $50 and see what happens. - **Talk to real customers.** Not your mom or your best friend. Real strangers who might pay for your solution. - **Build a prototype** with basic tools. Nothing fancy. Just enough to show what you mean. The goal isn't to build a perfect product. The goal is to learn. And you can learn a lot with very little money if you're smart about it. ### The Real Value of Failing Early Failing early isn't about being reckless. It's about being smart. When you test a small version of your idea and it fails, you learn what doesn't work. That knowledge is gold. It saves you from making the same mistake on a much bigger scale. Flip says the best entrepreneurs are the ones who fail the fastest. They try things, they stumble, they adjust. They don't get stuck in analysis paralysis. They move. And because they move, they find the right path sooner. > "The biggest risk is not taking any risk. In a world that is changing really quickly, the only strategy that is guaranteed to fail is not taking risks." - Mark Zuckerberg ### Making Better Decisions Before Big Investments Here's the bottom line: before you invest big money, test small. Before you build a factory, build a prototype. Before you hire a sales team, see if anyone wants to buy. Flip's approach is about making decisions with data, not guesses. He's seen too many entrepreneurs bet the farm on an idea that nobody wanted. Don't be that person. Test early. Fail fast. Learn constantly. ### What This Means for Your Business You don't have to be a tech startup to use these principles. Any business can benefit from testing ideas before going all in. Whether you're launching a new product, opening a new location, or changing your pricing, test it first. Start small. Learn fast. Adjust. And when you find something that works, pour on the gas. That's how you grow without taking unnecessary risks. This conversation with Flip Keijzer is packed with practical advice for any entrepreneur who wants to build a business that lasts. The key takeaway? Don't wait for perfection. Start testing today. Your future self will thank you.
