Business Insider has done some serious digging and discovered that Mac OS X architect Bertrand Serlet, who left the company in March 2011, has founded a cloud computing company called Upthere in Palo Alto, California. According to a variety of trademark filings, tweets, job postings, and tips, Serlet is building some kind of Cloud OS with none other than Roger Bodamer, one-time VP of Production Operations Development at Apple. "Our founders were key to building the world's leading operating system (Mac OS X) and database (Oracle) and have a clear vision of core technology for a Cloud OS," a job posting said.

Serlet's departure was a big hit for Apple, considering his extensive work on Mac OS and experience working with Steve Jobs. Apple's departure announcement for Serlet reads:

Serlet joined Apple in 1997, and has been involved in the definition, development and creation of Mac OS X, the world's most advanced operating system. Before joining Apple, Serlet spent four years at Xerox PARC, then joined NeXT in 1989.

"He was basically the Jony Ive of Apple’s software design," Brian X. Chen wrote for Wired. While Business Insider's sources appear sound, we won't know for sure what Serlet's been up to until we hear it from the horse's mouth.
