The CEO handover was just one of a number of changes to the Ibrix management roster, which also saw Ed Callahan replace Bill Norberg as vice president of worldwide sales. "He's pursuing his own personal interests," says Gilbert, adding that Norberg took the decision to move on.

Another high level exec leaving the firm was COO Michael Malone. "With me coming in here, we felt that there was no need for a COO [because] I have that experience, so Mike left," says Gilbert.

Ibrix marketing VP Joe DeRosa also jumped the train out of the firm, leaving "to pursue other interests" earlier this year. This week, the startup appointed his successor, promoting former product marketing director Milan Shetti to vice president of marketing and business development.

The new CEO denies the suggestion that all this upheaval reflects an undercurrent of trouble at the firm. "I don't believe that it is a revolving door," he says. "John and the board took the decision that it was time to move the company forward and get into execution mode."

Enterprise Strategy Group analyst Steve Duplessie believes Ibrix's changes have more to do with future strategy. "It's not that they are in trouble," he says, pointing to users such as Pixar and Disney that use the Ibrix kit. (See Disney, Pixar, and Ibrix Touts Media Sector Growth.) "They have got some good customers and big implementations."
