avid Nordberg has previously worked with digital gaming companies Electronic Arts and King.
Oscar Mühlbach takes on the new role having recently held the same position at ecommerce company Footway.
Nordberg said: “We're at the dawn of a new era where the boundaries between real money and free-to-play games are rapidly broken down and merged into a hybrid business model. Gaming companies are forced to think outside the box and look for new innovative ways to market and promote themselves.
"We already know brand values and customer sentiment matter so much more than big TV advertising campaigns. It’s in this context I’m joining one of the strongest brands in the industry. I'm excited and proud to start a new journey together with a management team which has a vision set on changing the gaming industry forever,” he remarked.
Mühlbach said: "I am thrilled and honoured to get the chance to join Mr Green in these exciting times for the industry. The company has a successful track record of growth and most importantly a fantastic team ready to take the Mr Green customer experience to the next level."
