BANGLORE, INDIA: Retiring from Microsoft hasn't kept Bill Gates quiet! The man behind Microsoft, the software giant, Gates is planning to start a new company in Kirkland, USA.

According to the news report published in Techflash, a technology news website, Gates new venture, bgC3 LLC, is a new baby as a think-tank that was founded after he quit his duties with Microsoft after 33 years.

Is this Bill Gates' next big business? A Gates insider gives an emphatic no, saying it's not a commercial venture but rather a vehicle to coordinate the software mogul's work on his business and philanthropic endeavors, the website added.

However, bgC3 will also oversee Gates' personal pursuit of breakthrough ideas in science and technology. The insider said the goal isn't necessarily to create new companies, although ideas could be passed along to Microsoft Corp, the report added.
