Diligent Achieves Global Growth Milestones, Surpassing 100,000 Users as Boards and Senior Leadership Embrace SaaS

Users From 62 Countries Across Seven Continents and More Than 35 Percent of the Fortune 1000 Leverage Diligent Boards

NEW ZEALAND – JULY 29, 2015 — Diligent Corporation (NZX: DIL) announced its continued growth, surpassing 100,000 users of its Diligent BoardsTM solution. The Software-as-a-Service (SaaS) based platform transforms how companies manage the secure electronic production, distribution and collaboration of confidential information to their boards, committees and leadership teams.

Diligent is now more than double the size of its nearest competitor in terms of clients and is a truly global provider. It has clients in over 60 countries and users on all seven continents – even Antarctica.

Additionally, more than 35 percent of the Fortune 1000 uses Diligent Boards. The solution remains the most widely used of its kind and Diligent has a 99 percent* client retention rate, one of the best in the SaaS industry. Diligent Boards drastically simplifies collaborative business and governance as a strategic enabler for securely receiving and reviewing board materials through any device.

“Collaborating across a board can be difficult in most organizations, but it is even more of a challenge when you need to work in remote locations such as Antarctica,” said Peter Smith, General Manager, Corporate Services and Strategy of Antarctica New Zealand, a government entity responsible for developing, managing and executing activities in Antarctica and the Southern Ocean. “Diligent Boards is an easy-to-use and secure tool that keeps our board aligned and enables us to collaborate and make key decisions to help support our organization’s activities in respect to Antarctica.”

Last month, Diligent received a Gold Stevie® Award in the “Customer Service Team of the Year” category and a Silver Stevie® Award in the “Customer Service Department of the Year” category, recognizing the company’s continued dedication to providing its more than 100,000 users with exemplary service ̶ regardless of their locations.

“The momentum we’re experiencing is extremely vital as it illustrates a shift in senior leadership’s understanding and value of SaaS services. Companies around the globe are increasingly trusting their most important and sensitive materials to Diligent,” said Brian Stafford, President and Chief Executive Officer of Diligent Corporation. “The lack of visibility around SaaS adoption in broader enterprise and executive settings is at a turning point. Some board members may not even know that Diligent Boards is a SaaS tool as its secure and intuitive design, empowers effective information flow around the most business critical decisions using the cloud.”
