Three years ago, I had a really cool business idea that I fell in love with. I spent 5 months developing it before realizing that it's crap. Right from the beginning I felt that no one was willing to pay for it, but I just kept kicking the can down the road by designing logo, website, etc. Several months later when I finally tried to sell my product, my expectations were confirmed.
Nobody would buy it. "Why the hell did I lose so much time on this idea" I kept asking myself.
Trying to avoid the same mistake, I decided to turn my entrepreneurial process upside down. Since then, I've used the system explained in this article to win customers for my ideas even before I had the product.
In my last idea, which I have tested together with Patrick, we did some basic research, developed the prototype and sold the product (before it was developed!) in less than 10 hours. Our logo was basic, we didn't have a website (and still don’t) and we did not register a company, however, we got the first 5 customers and earned 150€ in one working day.
