The story

Founded 2017 as a B2B API aggregating airline NDC content so any company could sell flights without IATA accreditation. Expanded to Stays (hotels) and Cars, and layered embedded payments (Duffel Payments, built on Stripe) and a prepaid Balance product so customers can pay airlines directly through Duffel. Current positioning targets both traditional online travel sellers and non-traditional distributors (challenger banks, spend-management platforms) wanting to embed travel booking.
