About Duffel

Duffel is a technology-driven company that operates in the travel industry, providing a suite of application programming interfaces (APIs) that streamline the process of searching, booking, and managing flights. Its services are primarily targeted towards travel sellers, including both traditional travel agencies and non-traditional sellers like Pelikin, who are looking to diversify their revenue streams.

Duffel's business model is centered around its comprehensive APIs, which are designed to be easily integrated into clients' existing systems. These APIs allow clients to access multiple airlines, manage changes and cancellations, offer paid seats and bags, and provide pay-later options, among other features. This not only enhances the end-to-end customer experience but also gives clients a competitive edge in the market.

The company's APIs are supported by extensive documentation, user guides, and client libraries in Node.js, Python, and Ruby. This, coupled with prebuilt components like seat selection and payments, makes it easier for clients to design a great user experience for their customers.

Duffel generates revenue by charging its clients for using its APIs. The more features clients use, the more revenue Duffel makes. This makes Duffel's revenue model scalable and directly tied to the success of its clients.

In summary, Duffel is a technology company that provides comprehensive API solutions to travel sellers, enabling them to enhance their customer experience and diversify their revenue streams.
