No website is yet available (just minor details) on his new company called bgC3 headquartered in Kirland, Washington just minutes from Gates’ mansion — a secret company with a cryptic name and even its own logo.

According to an insider, bgC3 stands for Bill Gates Catalyst 3. The ’3′ for Gates’ third enterprise after Microsoft and Bill and Melinda Gates Foundation. The company is registered as a "holdings" company and was originally called Carillon Holdings. Registered in March 2008, Gates changed the name to bgC3 later in July.

Many experts believe it is a "think tank" for advanced future technologies such domestic robots and automobile operating systems. In late 70s, Gates said everyone will own their own personal computers. People laughed in his face. Now, Gates wants a robot in every home and an Auto OS in every automobile.

Actually, bgC3.com does exist, but it only has the logo. Nothing else on the website.
