Sodi told an analyst briefing the company has branched out into new customer territory, attracting a major hospital operator in the US, with more than 500 users in the quarter.
"These other industries are very exciting - it's not what you think are the boardroom, but they still need to communicate to their committees," he said.
Diligent continued to build its cash position, with an operating cash inflow of US$9.29 million in the half, leaving it sitting on cash and equivalents of US$61.7 million.
Sodi said the board's priority for cash is to continue to grow the company, and hasn't got any plans to return that to shareholders.
Diligent opened a new research and development centre in Charlotte, North Carolina in the second quarter, hiring 14 staff and is aiming to have 30 programmers at the location by the end of the year.
Sodi said the Charlotte site was primarily to reduce the cost of hiring programmers, which is expensive and protracted in New York.
The company is emerging from administrative errors that forced it to restate its accounts for the 2010 through 2013 financial years after incorrectly recognising revenue, having also had to backtrack after granting too many options to Sodi.
General and administration costs of US$7.8 million in the quarter are expected to be lower in future, as the period captured one-off costs related to the restatements and executive bonuses, interim chief financial officer Alex Sanchez told the briefing.
