“After extensive A/B testing of Karmafy in Dancing With The Stars I was amazed at the positive effect that doing good through Karmafy had on our player engagement.  I am delighted to be able to empower all our players to have a positive impact on the world, simple by playing our game.“
— Nick Harper, Head of Studio at Exient UK.

Karmafy Freemium Philanthropy

Increase your revenues, decrease your acquisition cost, and build a following with purpose. 

We know that developers today are faced not only with the challenge of writing great games, but also acquiring, retaining, and monetising players in an ecosystem where costs are spiralling and differentiation is key. Karmafy drives acquisition and engagement by empowering your game players to come together to support great causes and charities within your games, and to share their successes with friends and family.

Our engagement platform turns players into payers, increases virality, and builds a studio following by empowering the community to collaborate as a force for good, converting them to brand ambassadors and evangelists. By creating meaningful reasons for players to pay and share, you as a developer can grow your revenues and market share whilst controlling cost of acquisition.

Results from Driving Engagement with the Power of Doing Good

Karmafy has been part of A/B tests over 140.000 players in Slam Dunk Basketball 2 and Dancing With The Stars. The results showed that adding Karmafy had the following impact on players and behaviour:

  • Social media sharing up 100% to 200%

  • Conversion to paying up 5% to 10%

  • Average revenue per user up 25% to 42%

  • Retention D7 up 5% to 10%, D30 up 10% to 20%


Demo Game

For a quick demo of Karmafy in a game we recommend you install the game Swim Dash. It has a somewhat accelerated Karmafy experience. Keep in mind that the Karmafy UI is completely skinnable and that each game and charity is individually gamified.
