If there's any piece of advice that you'll hear over and over again when starting a business, it's that you should find a problem that no one else is solving, and solve it. Sites like Amazon and Ebay...that first gelato or cupcake shop in your city...they all did it.
Well, I was puttering around DSTRYRsg today (I don't know why I don't spend more time on this blog) and ran across JGP.com...that stands for Just Gi Pants. Their mission? To solve the problem of gi pants that pass away before their time. Considering that companies are starting to sell pants separately more, I'm not sure if these guys are going to see a natural whittling away of the problem they've solved for just $39.99 a pair, but kudos to them for finding the hole.
