Maureen Sullivan
Company: AOL
Current CEO: Tim Armstrong

Maureen Sullivan is not the heir apparent to the AOL top spot -- yet. Her official bio describes the not-yet-30 executive as "one of the key strategists at AOL." She is now the senior vice president of corporate communications and marketing, but joined the company as an assistant to AOL CEO Tim Armstrong, with whom she had also worked at Google. Sullivan was reportedly a big part of AOL's rebranding push -- in a way personifying a hipper, younger version of the brand. Next-generation C-suite, indeed.
