A critical theme in international business and innovation pedagogy is preparing future business leaders and policymakers to address and solve the “Grand Challenges” of today. These challenges necessitate coordinated and sustained efforts from diverse stakeholders toward clearly defined goals, with solutions often emerging from social and technological innovation. Consequently, international business education, particularly in innovation, serves as a starting point for tackling these Grand Challenges. This paper examines the role of international business programs in addressing Grand Challenges through short-term international educational exchanges that promote multi-stakeholder, cross-sector collaboration, specifically through business innovation camps. We present insights from two three-week international innovation camps held in 2023 and 2024, a collaboration between two business schools – one in Finland and one in Mexico. These camps aimed to develop innovative solutions for the global issue of overweight and obesity using design thinking. Students engaged with representatives from Finnish and Mexican businesses, researchers, and experts, facilitating design thinking and service prototyping. The camps provided immersive, experience-based learning for students and offered development opportunities for instructors and external stakeholders. Overall, the camps enabled productive and creative interactions among diverse stakeholders, fostering solutions that would be unlikely achievable in other settings.
