Customer stories

Since 2014, we have been empowering organisations to grow their positive impact. We do this from the heart, through their employees. Over the past years, we have challenged thousands of employees across various organisations to take small but meaningful steps towards a sustainable life together. These challenges bring sustainability into the heads, hearts, and hands of your employees. All of a sudden, a global problem becomes manageable and a sustainable future achievable. But we are not done yet! Read how we have helped organisations involve their employees in their sustainability strategy and join us in making even more impact.
