About us

Bold Donut was started by Nathan and Kate. 

The idea came from Nathan who recognised the need to frame climate action and a vision for the future in a more positive and engaging way, because as Kate said “the doom and gloom isn’t very inspiring.”


They turned to games because they believe that games are a safe and fun way for people to experience climate-positive behaviours and possible futures without fear of judgement or making a mistake.
