Iceland-based airline technology provider Dohop has secured a multi-million-pound investment from Scottish Equity Partners (SEP), the first and largest investor in Skyscanner.

Dohop did not disclose the exact amount of the funding but CEO David Gunnarsson says its total funding is now nearly €20 million.

Dohop provides flight search and virtual interlining technologies that enable travelers to combine flights from low-cost carriers, full-service carriers and hybrid airlines into a single itinerary. The interlining solutions also provide protection and assistance for passengers if there is a missed connection, schedule change or cancellation.

Among its 35 airline and airport partners are EasyJet, Jetstar, Transavia, Avianca, Eurowings and Gatwick Airport.

With this investment, the company say it will expand its sales and support teams and accelerate development of its interlining solutions, including the addition of train tickets to customer itineraries.

“Joining forces with SEP will enable us to become the technology provider that airlines need now more than ever, on a global scale and with the resources to connect every airline to their partners of choice. In just over three years, we have built the world’s largest next generation interline platform,” Gunnarsson says.

“With SEP’s support, we plan to connect the world’s leading airlines, airports and other travel providers into a platform that allows them to increase passenger choice and confidence about travel. SEP’s experience of growing global technology leaders, and their unique insight into travel distribution, made them our partner of choice for this funding round. We are delighted that they have chosen to back us on our mission to revolutionize travel connectivity.”

SEP backed Skyscanner with a $192 million round in January 2016.
