How do you plan to maintain the data in Sure? You mentioned that you crowd-sourced the current data in SF and Copenhagen from local bloggers, but did you had somebody double check these places? What happens if one of these places do get shut down or closed? Having a chatbot on Messenger means that people are placing trust on you - and will be hard to gain back once it's lost or given a bad choice of place. Will people be able to flag places as closed within the conversation? What about preferences? E.g. If I don't want to be recommended the same place again next time I talk to Sure?
All this aside, great job guys! Try to surf the ride and do not fall down!
