Join us in harnessing the collective power of innovation to tackle some of today's most pressing challenges!

Cities are vital for economic development and social progress, with over 50% of the world's population living in urban areas. However, rapid urbanisation is putting a strain on infrastructure, resources, and services, leading to overcrowding, pollution, and other negative impacts.

Climate change poses a significant threat to cities worldwide, with sea levels projected to rise by up to 1 metre by the end of the century, putting coastal cities at risk of flooding and storm surges. Bridging the infrastructure gap is also essential, as many cities worldwide lack sufficient investment in this area, with Nigeria alone needing to spend about $3 trillion over the next 30 years.

We are calling on all entrepreneurs, thinkers, and doers within the community of Germany alumni to develop innovative and entrepreneurial ideas to address such challenges. Solutions that can help cities become more sustainable, equitable, and resilient are needed. Your solutions can have a significant impact on people's lives globally.
