About
KAYAK is a travel metasearch engine founded in 2004 by Steve Hafner and Paul English, acquired by Booking Holdings (then Priceline Group) for $1.8B in 2013. Headquartered in Stamford, Connecticut, KAYAK aggregates flight, hotel, car rental, and vacation package results from hundreds of travel sites, enabling one-click comparison shopping. Its product suite includes KAYAK.com, the Momondo brand (acquired 2017), HotelsCombined, and a business travel management platform, KAYAK for Business.\n\nKAYAK's revenue model is primarily CPC (cost-per-click), charging airlines, OTAs, and hotels for qualified referrals rather than taking a booking commission. This metasearch model positions KAYAK as a neutral aggregator rather than a competing OTA, though it also offers direct booking through its platform in select categories. KAYAK for Business targets corporate travel managers with policy controls and expense integrations.\n\nAs a wholly owned subsidiary of Booking Holdings ($26.9B revenue FY2025), KAYAK does not report standalone financials. It remains one of the most visited travel websites globally, with over 300 million monthly searches across its brand portfolio. KAYAK's AI trip-planning features and integration with Booking.com inventory have strengthened its position as a one-stop travel research tool heading into 2026.

About
IDeaS Revenue Solutions is a revenue management software company founded in 1989 and headquartered in Minneapolis, Minnesota, that provides AI-driven pricing and revenue optimization technology to hotels, resorts, and hospitality operators worldwide. The company was founded with a focus on bringing quantitative revenue science to the hotel industry at a time when most pricing decisions were made manually based on experience and intuition. IDeaS is owned by SAS Institute, the analytics software company, which acquired it in 2003 — giving IDeaS deep analytical infrastructure and resources to build increasingly sophisticated demand forecasting and pricing models.\n\nIDeaS' core product is its Revenue Management System (RMS), which uses deep learning algorithms to forecast demand, optimize pricing across room types and rate categories, and automate revenue decisions in real time. The system integrates with property management systems, central reservation systems, and channel management platforms to deploy optimized rates across direct and third-party booking channels without manual intervention. IDeaS serves over 13,000 clients across 140 countries, ranging from independent boutique hotels to major chains and resort groups. The company has expanded beyond rooms revenue into meeting and events optimization and total revenue management approaches.\n\nIDeaS reported 426% year-over-year revenue growth for 2023-2024, reflecting both strong hospitality market recovery and accelerating adoption of automated revenue management as hotels seek to maximize yield across increasingly complex channel and booking environments. Its SAS ownership provides long-term stability and access to cutting-edge analytics R&D, while its 13,000-client customer base and 35 years of hospitality-specific data create a compounding advantage in model accuracy that pure-technology entrants find difficult to replicate.
