Our take
Trainline make it super easy to book transport tickets. Its app is intuitive and well designed and its even pioneering paperless travel, allowing users to store their tickets in the app.
It's hyper-focused on customer experience and has a product culture of fast iteration to deliver great outcomes for customers. Its customers make 170,000 journeys a day and it sells 200 tickets a minute.
Its continuing to innovate to stay ahead, using machine learning to predict price movements and integrating with Siri and Google Assistant so people can buy tickets simply by speaking to their phone.
