More about Hopper

Despite the pandemic’s impact on the travel industry, Hopper has emerged stronger than ever. As the travel industry continues to rebound, Hopper has demonstrated significant outperformance with its category-leading mobile-only marketplace, delivering value to customers and supply partners with the company’s proprietary suite of fintech offerings.

Here are just a few stats that demonstrate the company’s recent growth:

- Hopper’s valuation is now over $5B, which is more than triple our valuation from early 2020.

- The company grew its revenue by more than 300% YoY in 2021. Hopper’s monthly revenues are now 375% higher than its pre-pandemic high point and Hopper Cloud, Hopper’s new B2B initiative, is already 15% of its revenues and growing.

- According to Apptopia, Hopper was the #1 most downloaded OTA in the US in 2021. The app has over 70 million downloads.

Hopper Cloud partners include Capital One, Kayak, Marriott, Amadeus,, and MakeMyTrip.

The industry opportunity for Hopper Cloud is enormous as projections estimate that if all travel distribution channels offered travel fintech, it could increase the total consumer spend for the sector by $200 billion annually.

And all this recent growth is just the beginning. There are still so many new opportunities we’re excited to tackle in the next year!
