What Bold Donut Is All About
Bold Donut is on a mission to scale climate engagement and impact through gamification. Forget the usual “doom and gloom” approach. Instead, they capture attention actively, bring joy rather than anxiety, and empower people instead of overwhelming them. It’s about making sustainability something people want to be part of, not something they dread.

The Story Behind Bold Donut
Bold Donut was founded by Nathan and Kate. Nathan’s initial spark came from exploring how demand flexibility campaigns could shift energy customer behaviours. From there, they realized the need to frame climate action in a more positive, engaging way. Digital games, especially those like Candy Crush, seemed like the perfect medium — easy to pick up, fun, and played by millions worldwide. So, they set out to create games that make sustainability approachable and enjoyable.
