They fail because they build the wrong product.
In The Lean Startup, Eric Ries introduces a powerful idea: Don’t guess, test. The best businesses don’t rely on big plans and assumptions. They experiment, adapt, and grow fast.
Here are 3 game-changing lessons from the book:
1️⃣ Build → Measure → Learn.
• Don’t wait for a “perfect” product. Launch fast, gather feedback, and improve.
• The faster you learn, the less money and time you waste.
2️⃣ Your idea isn’t a business; your customers make it one.
• You might think you know what people want, but real validation comes from paying customers, not opinions.
• Talk to users early and often.
3️⃣ Pivot or persevere?
• If something isn’t working, don’t double down, adapt.
• The best founders stay flexible and change course when needed.
💡 Biggest takeaway? Success isn’t about having the best idea but learning faster than everyone else.
