Troubled travel software company Datalex has appointed of David Hargaden as its new chairman with immediate effect. 

Mr Hargaden has also been appointed as a non-executive director at the company.

He is currently chief executive of Unity Technology Solutions, one of the country's biggest IT Managed Services businesses. 

Mr Hargaden is also a non-executive Director of ding.com, the international mobile top-up provider and is a former non-executive chairman of Cartrawler.com, Europe's largest car rental site.

A founder and former non-executive chairman of property website myHome.ie, he was also head of corporate finance at BDO Ireland.

Datalex's CEO Sean Corkery said that Mr Hargaden brings significant board experience and relevant industry knowledge that will strengthen the company and provide a fresh perspective. 

"His appointment allows me, as CEO, to focus on the running of the business and to lead Datalex to future growth," Mr Corkery said.

"I am excited to join the Datalex Board as chairman and I am confident there is a significant market opportunity for Datalex, " David Hargaden said.

"My technological and sectoral experience can be leveraged to support Sean, and the wider team, so we can ensure Datalex achieves the success it deserves," he added.

A delay to Datalex's publication of full year results led to the suspension of its Dublin-listed shares in April, while its chairman Paschal Taggart and CEO Aidan Brogan also resigned earlier this year.

In September, the company reported a much bigger than expected loss of $50m for 2018, after what it described as the "most difficult year in the history of the group". 

Datalex had reported profits of $7.1m the previous year.
