Taptica has appointed an interim chief executive after accepting the resignation of former CEO Hagai Tal.

The global company, which is listed on the AIM market of the London Stock Exchange, is a specialist in advertising technologies for performance-based mobile marketing and brand advertising.

The firm announced on Monday that Hagai Tal had handed in his resignation after he was found liable for certain statements made in relation to the sale of Plumus Inc, a company of which he was both a shareholder and chief executive officer at its time of sale in August 2011.

Taptica has this morning confirmed that Tal's resignation has been accepted and that Rivi Bloch will serve as interim CEO until a permanent boss is found.

Bloch is currently division CEO of the Taptica Performance Advertising business.

"After due deliberation, the board has accepted the resignation of Hagai Tal," said chairman Tim Weller."The board is grateful that he moved promptly to put Taptica's interests ahead of his own by tendering his resignation immediately.

"We are also pleased to be able to confirm that he is staying on to ensure minimal disruption to the operations of the company.

"Taptica has such strength and depth in its senior management team that we are not short of viable candidates to take the company forward. We are delighted to appoint Rivi Bloch as interim CEO.

"She has been with us for the past five years and has been instrumental in growing Taptica's global presence and offering while maintaining an exceptional level of service. We look forward to benefitting from her experience as we move ahead."

Taptica operates from global offices in San Francisco, Israel, New York, Beijing, Korea (Seoul), Tokyo and London.
