At first, the app we made was just for pure fun. It was so popular in Hungary and also got some feedbacks from the surrounding countries that we wanted to open up to the world.
We didn't have any business plan at all but someone suggested ppl might like posters if they look gorgeous. This idea is outside from our group so thought this could work. Also told some friends who liked the idea although asking friends about this is probably not the best validator.
If there where some interest in the posters we would create customized maps. Your routes vs others' routes.
We are also open for other suggestions :) - Putting stores on the map who can advertise? - Sell the data to governments to use it as an input for cycle route planning?
