Terms of the deal have not been disclosed.
Private equity firm Warburg Pinkus brokered the earlier merger as part of a plan to create a new global brand to provide tech to airlines, agencies and freight handlers.
Anari runs as a business intelligence consultancy and software development provider, covering areas such as “revenue integrity” and passenger profiling.
Accelya managing director, Jose-Maria Portabella, says:
“This acquisition gives our team significant new opportunities to help airlines combine and enhance the traditional revenue integrity and revenue assurance processes, to amplify their revenue protection capabilities.”
