How can one's own activities as a strategic designer be put at the service of sustainable development goals? The author's vehicle is creative Swiss micro-entrepreneurs who want to achieve sustainability with their products and practices, but are reaching their entrepreneurial and economic limits. In three self-designed design prints, the author tests whether and how he can systematically empower micro-entrepreneurs to develop sustainable solutions for their products, services and entrepreneurial practices. As a result, he reflects on his design process and adapts it to include key insights: for example, he wants to communicate with his clients in a more target group-oriented way in the future, clarify the goals of the sprints or strengthen the follow-up of sprints.
