The year at Trainline in numbers 2016
2016 has been a very busy year at Trainline as we have been growing at a rapid pace. This means our tech team has had to work hard to scale effectively and cope with the sheer demand.
New product teams have been springing up all through the year, while older teams have grown and been split into sub-teams to maintain the essential agility of small teams. With such growth, we have needed to ensure our processes were in good shape to manage the increased complexity that this brings.
Here are a few fascinating stats which tell a short story of the year at Trainline …
