CertiVox has announced the appointment of former Clearswift CEO Richard Turner as a non-executive director.

Highly commended in the CEO of the year award at the 2011 SC Magazine awards, Turner brings nearly a decade of board-level experience to CertiVox. Also named as non-executive director is Pieter Knook, who previously led the Vodafone internet services unit and worked for Microsoft.

Brian Spector, CEO of CertiVox, said: “I can't express how excited and proud I am that Pieter and Richard, with their proven expertise, have decided to join our already dynamic and innovative board.

“Pieter and Richard are absolutely the right guys to help us drive our strategy, product offerings and customer development to ensure that we deliver on these opportunities. I can't think of anyone who would be a better fit for this role.”

Al Sisto, executive chairman of CertiVox, said: “The expansion and strengthening of our board is an important move for a ground-breaking business. CertiVox is moving forward into its next stage of development and Pieter and Richard bring the incremental expertise that we will leverage to make the leap. I am looking forward to working with them.”
