As entrepreneurship educators, we typically bring together students in entrepreneurial teams and let them develop and work on their own ideas. Most of the time, their ideas are innovative, interesting, and inspiring. They also increasingly take sustainability into account, still this needs to be fostered systematically. So how could we support these students to tackle global challenges and develop sustainable ideas? To develop more sustainable ideas, entrepreneurship education concepts need to bridge the perspectives of multiple stakeholders. Developing innovation communities within a framework of an open innovation process presents a suitable approach with a possible long-term impact in this regard. The “Sandbox Innovation Process” combines a structured open innovation process while fostering an innovation community enabled to solve regional challenges. Using this workshop concept, participants can experience the “Sandbox Approach” at firsthand and develop comprehensive concepts for their common challenges. This workshop is a starting point to reflect on how researchers and educators in entrepreneurship can become key drivers for developing sustainable solutions. This is supported by a framework that takes contextual constraints into account and reflects on the Sustainable Development Goals.
