NTT Communications Corp. has offered to buy a 91.2% stake in Arkadin International, one of the world's largest collaboration services providers, from AXA Private Equity. The acquisition agreement is currently going through the regulatory approval process.

Arkadin offers conference-related solutions, including audio, web, video conferencing and unified communications services. It serves approximately 37,000 customers in 32 countries, including France, Germany, the UK, US, Australia, China, Singapore and Japan.

Since AXA Private Equity’s investment in 2012, Arkadin has experienced double digit revenue growth and has been able to reinforce a leading market position through a number of developments, including the acquisition of video-conference specialist Novasight, according to NTT.

NTT said its customers had been seeking to lower their costs and streamline operations by integrating internal communication tools with NTT Com’s Arcstar Audio Conferencing, Arcstar Web Conferencing, Arcstar Video Conferencing and cloud-based Arcstar UCaaS unified communications service.

Toru Maruoka, senior VP of voice and video at NTT, said, “With the acquisition of one of the fastest growing players in the industry, NTT Com reaffirms its ambition to develop services in the collaboration business for all of its partners and clients across the world.

“Arkadin’s global seamless customer service and infrastructure will strengthen NTT Com’s offering in both global conferencing services and total solutions, incorporating unified communications.”
