If you haven’t heard of Ashley Madison yet, let us tell you how this business thrives on a moral flaw – infidelity.

Ashley Madison is a social media website/app that caters to people that want to cheat on their partners. Only married people or those who want to date married people can sign up on the site and hook up, anonymously!

Ironically, a happily married man (or is he?) is the founder of the site. The site’s slogan? “Life is short, have an affair.”

Ashley Madison went on to become a million-dollar company. As of 2014, the website reported a revenue of $115 million. However, it lost its reputation for discretion in 2015 when a cyberattack exposed data of 32 million users. The website has regained its function and users can sign up to get help with their infidelities.

2. Goggles for your Dog


Bow-wow! Just like the dogs chilling in “Who Let The Dogs Out”, there’s a business that manufactures specially designed goggles for dogs.

Doggles was the brainchild of Roni Di Lullo, a programmer for HP. What started as a personal experiment to protect her dog’s eyes, went on to become a large scale business.

“I hadn’t really thought of it as, ‘This is just a product I’m going to sell a ton of. ‘… It really was for fun, but once I did it, I realized there really was a market for this,” Di Lullo said in an interview.

3. Slinky

One of the most popular toys of the previous century, the idea for the slink occurred to naval engineer Richard James when he accidentally knocked over a spring in 1943. Inventing a toy out of it seemed like a silly idea. But the slinky made over £180 million in profits and went on to become a very popular toy.

4. Slanket


A slanket is literally a blanket with holes in it!

The creator of the product, Gary Clegg, decided to cut a hole into his blanket so that he wouldn’t have to remove his hand from the covers to change the channel with his remote. Garr then decided to mass produce this weird invention of his.  It was made into a blanket with sleeves.

Within a few months, he sold thousnds of slankets across the globe and made around £350 million in profit.

5. Pillows in the Oven!

Did you know the smiley face, which is a billion-dollar business today, was the invention of Harvey Ball, a commercial graphic artist who just got paid $45 for patent rights? He designed it as a part of his company’s friendship project and came up with the idea in less than 10 minutes!

Two brothers Bernard and Murray Spain bought rights to the design and started using it on every product possible in their novelty store. They opened a dollar-store chain and made millions. They sold it off to Dollar Tree for $500 million in 2000.

7. Pet Rock

The pet rock took the world by a storm in the 90s when Gary Dahl came up with the genius idea of packaging a stone, setting it in a nest of wood shavings and placing it in a cardboard box with holes along with a training manual full of puns and jokes!

The idea was to have a pet, without having to take care of it. What better than a stone? Dahl sold 1.5 million rocks for $27 million!

Talk about turning stones to gold!
