BetDash.com was a social web application for sports betting. Users could not only wager using web & mobile, but also connect via Facebook with betting fans all over the world. The startup was acquired by Paddy Power.
That was a really engaging project. We needed to take care to not get addicted ;) A couple of our team members worked as much as 20 months on the web and Facebook apps. We were responsible for backend and frontend of the apps based on a present design.
