Tapulous, which develops Apple (AAPL) iPhone game apps, got its start in 2008, with the help of high-profile angel investors like Salesforce.com's Marc Benioff and Sun's cofounder, Andy Bechtolsheim. Since then, the company's growth has been stunning. There are now 17 million users. Is it any wonder that Tapulous' website says: "We love the iPhone"?In fact, the company is clearing about $1 million a month from the iPhone. Much of this is due to the popularity of the Tap Tap Revenge game, which is quite addictive. Kind of like Guitar Hero, you can punch out tunes by tapping your iPhone.
