About kwiff

Kwiff is not gambling as you know it. It’s a new approach to sports betting and casino focusing on giving each player an individual experience. We are determined to challenge the industry by being outrageously innovative and product focused – building the gambling company of the future. To be in total control we have built our own tech platform including a fully automated sportsbook. We have launched our native iOS and Android apps on the UK market, offering our customers best-in-class UX/UI. Our ambition is to offer the best gambling experience and we have the knowledge, resources and courage to make it happen.

Kwiff was founded in 2015 and we have been on a rocket trajectory since with already more than 65 employees across our London and Malta offices.
