Our history

The Cloud Communications division of NTT was formed in July 2019 when Arkadin joined 31 other companies including NTT Communications, Dimension Data and NTT Security to form NTT Ltd.

Arkadin was founded in Paris, France in 2001 by Olivier de Puymorin, and grew from a small start-up to a global organization. Throughout the subsequent years it acquired and merged with numerous subsidiaries such as ConferencePlus, Novasight, AccuConference and Applicable, who all contributed to the ongoing success of the company. Arkadin was acquired in 2014 by NTT Communications, one of the largest telecommunications companies in the world, and became part of Nippon Telegraph and Telephone Corporation.

Today, as a proud member of the NTT Ltd. and NTT Group, we can ensure that customers’ IT needs can be met through one business partner, from consultancy and architecture design to systems integration, security and cloud services.
