The Hopper platform serves hundreds of millions of travelers globally and continues to capture market share around the world. Hopper’s app has been downloaded over 120 million times and is popular among younger travelers. In recent years, Hopper has evolved into a travel fintech provider, commerce platform, and global travel agency that powers some of the world’s largest brands.

Through HTS, our B2B division, the company supercharges its partners’ direct channels by integrating our fintech products on their sites or powering end‑to‑end travel portals. Today, our partners include leading travel brands like Capital One, Nubank, Air Canada, and many more.

Here are just a few stats that demonstrate the company’s recent growth: billions of dollars worth of travel and travel fintech are sold through Hopper and HTS’ channels every year. Our fintech products – including Cancel for Any Reason and Flight Disruption Assistance – have exceptionally strong CSAT because the terms are always clear, and customers receive instant, no‑questions‑asked resolutions. Almost 30% of our app customers purchase at least one fintech product when making a booking; and consumers are 1.6x more likely to repurchase if they add fintech to their booking vs if they booked just travel. Given the success of its fintech products, Hopper launched a B2B initiative, HTS (Hopper Technology Solutions), which represents more than 75% of the business.

Through HTS, any travel provider can integrate and seamlessly distribute Hopper’s fintech or travel inventory on their direct channels. As its first HTS partnership, the company partnered with Capital One to co‑develop Capital One Travel, a new travel portal designed specifically for cardholders. Other HTS partners include Air Canada, Uber, CommBank, Nubank, Flair Airlines and many more.
