CEO of SpinVox
London-based SpinVox burst onto the radar screen in 2007 when it announced some key deals with North American operators including Alltel and Cincinnati Bell. The privately held firm, which has developed a compelling voice-to-screen messaging solution, is the brainchild of Christina Domecq, the co-founder and CEO of the firm. Although not an industry "veteran" like many of the other women on our list, Domecq exemplified the type of drive and innovation necessary to succeed in this industry. And she's also one of the few women to head up a successful new startup.
