Travel software firm Datalex enjoyed a 15 per cent jump in transaction revenue during the four months to October.

In a trading update, the company, which is backed by businessman Dermot Desmond, said it anticipated adjusted earnings before interest, taxes, depreciation, and amortisation (ebitda) would grow by 18-20 per cent for the full-year, which is in line with previous guidance.

“Despite challenges in the business environment in 2014, including the impact of the weak dollar during the first eight months of 2014, we are confident that our full year guidance will be achieved,” the company said.

Datalex recently signed up a number of new clients, including New York-based JetBlue Airways, Brussels Airlines, which is a member of the Lufthansa Group, and Air Transat, Canada's leading holiday travel airline.

The company also opened a new office in Beijing to support its existing customers in the region and to exploit opportunities in China.

“2014 is a year of investment, performance and growth for Datalex with significant new deployments and investment in new infrastructure to scale our business for the future.”

“Our new customer signings and go lives in 2014 will help secure continued growth in our business in the coming years.”
