Open-Xchange, an open-source software company angling to cut into the Microsoft Exchange market, plans to announce two new top executives on Monday.
Gerald Labie, who had been chief executive of CXO Systems and chief operating officer of Novadigm, now is Open-Xchange's CEO. He replaces co-founder Frank Hoberg, who now is general manager of European operations.
Labie will be the first Open-Xchange CEO based in the United States; Hoberg was based in Germany.
In addition, the company announced it hired as chief technology officer Juergen Geck, who had been CTO of Novell's Suse Linux software but left one year ago.
Open-Xchange's server software handles e-mail, contacts and calendars. The company sells it both to companies that use it on their own and to Internet service providers such as 1&1 Internet that offer it to their customers as service.
