This is definitely true, and embracing the crazy ideas is a mark of an entrepreneur. This is especially true when the idea is actually about your bowel movement (ahem!) , as shown by the SQUATTY POTTY. The company makes stools designed to aid in bowel movement, the right way, by squatting instead of sitting while at the toilet. And they have explained the science behind it…
They appeared on SHARK TANK, and were able to convince the sharks and get $350,000 for 10% of stake in the company.
Since then the company has grown big, you can buy the product online: Squatty Potty Ecco 2 Pack-7″&9″
The moral for entrepreneurs, go crazy with your idea, you never know when the world goes crazy for your idea.
