TripAdvisor online travel service

TripAdvisor is the world's largest travel guidance platform, helping hundreds of millions of people each month become better travelers. Originally founded in February 2000 by Stephen Kaufer, Langley Steinert, Nick Shanny, and Thomas Palka, the brand was born in Needham, Massachusetts, in a small office above a pizza shop. The platform revolutionized the industry by focusing on user-generated content and honest reviews.

While the company was owned by IAC (InterActiveCorp) and later spun off from Expedia, Inc., it currently operates as an independent publicly traded company (Tripadvisor, Inc.). High-level control is exercised through voting power by Liberty TripAdvisor Holdings, Inc. The platform's digital services are developed and maintained primarily in the United States, though it operates localized websites across dozens of international markets.

As of 2026, TripAdvisor continues to be a dominant force in the global tourism sector, integrating travel planning, hotel bookings, and restaurant reservations into a single ecosystem while maintaining its headquarters in Needham, Massachusetts.
