Clark (pictured) replaces Allegiance’s founder, Adam Edmunds. He will remain actively involved as a member of the board of directors and will lead the company’s expanding partner and business development initiatives.

In a statement, the company says the new leadership will aim to help Allegiance “become a game changer and drive the trend toward customer empowerment with technology that helps companies achieve greater customer experience insight.”

In 2011, the firm secured $12m in a round of funding led by El Dorado Ventures.
