Trip Advisor, a leading travel portal, has acquired a mobile application GateGuru for an undisclosed amount. GateGuru offers flight and airport information, and would help Trip Advisor expand user-generated content and information related to airports, and insights on stores, restaurants and amenities. The GateGuru team will continue to operate out of New York. Steve Kaufer, co-founder and CEO, TripAdvisor, said, “This acquisition would help us expand our services in a fast growing segment.”
