It seems to be the week for news about LifeSize. Today the company announced record sales for the fourth quater and 2007 total. Annual sales reportedly tripled year over year. No actual numbers were announced, which is not surprising since LifeSize is a private company. According to Dun & Bradstreet, the company’s revenues are estimated to be $13.6M in the previous 12 months. Which means 2006 saw maybe $4M in sales. Not a bad growth trajectory, if our guesstimates are close to reality. Also announced today was the addition of Colin Buechler as the Sr. VP of Marketing. Colin was previously VP of Dell Americas. It’s an interesting move for Mr. Buechler, since his business unit probably sold $13.6M in keyboards alone last quater in the Americas for Dell.
