The program has been significantly expanded for 2025: Over 1,000 speakers, including 150 renowned figures from politics, business, and culture such as Agnès Buzyn and Hubert Védrine, will offer diverse perspectives on current and future challenges. This spectrum impressively demonstrates how innovation today is no longer just about technology, but requires interdisciplinary approaches that combine social, economic, and ecological aspects. Companies such as SAP, Adidas, and BMW are increasingly using Big as a platform to present their innovative projects and network with partners. The exchange of experience between established corporations and emerging startups is an essential driver for new business models and technological advances. The strong focus on connected mobility solutions and sustainable production highlights how German industry is maintaining its global competitiveness while contributing to decarbonization. The influence of Big 2025 will therefore also be of major importance for Europe’s future industrial restructuring.

The integration of various thematic paths, such as climate, health, and deeptech, offers participants targeted guidance to sharpen their individual innovation profile. A personalized visit, for example, allows for targeted networking with experts in the field of smart energy supply, which companies like BASF and Infineon are currently playing a key role in shaping. Big thus acts not only as a driving force but also as a strategic network to strengthen innovation in Europe.

The event impressively demonstrates how Europe’s economy is positioning itself in an increasingly complex world. The combination of research findings, practical business ideas, and political vision makes Big 2025 a groundbreaking event. Entrepreneurs and scientists alike draw on the latest findings, making the event a pacesetter for industrial and technological development.

The rapid development of artificial intelligence (AI) is one of the key factors shaping Big 2025. The event dedicates a dedicated area to the so-called “AI de la joie,” showcasing the latest applications in the field of generative AI. Users will experience both demonstrations and expert panels aimed at consciously and responsibly tapping into the potential of AI. Here, companies like Deutsche Telekom and SAP are relying on intelligent data processing and automation to drive efficient solutions in areas such as telecommunications and enterprise software.

AI technologies not only enable increased productivity but also significantly impact environmental and climate protection. Through precise predictive models for energy consumption and material efficiency, companies like BASF and Infineon are contributing to a more sustainable use of natural resources. This exemplifies the close connection between digitalization and ecological responsibility, which is a recurring theme at Big 2025.

The comprehensive program of masterclasses and workshops in this area is aimed at entrepreneurs and research experts who want to implement innovative concepts for the application of AI in industry. In addition to the automotive industry, such as BMW and Volkswagen, this also includes emerging business areas related to electromobility, which will be explored in expert presentations and live demonstrations at the trade fair. The long-discussed challenge of mass production of solid-state batteries for electric cars – a topic explored in depth in in-depth analyses such as this one – exemplifies the complex technological and economic issues facing both entrepreneurs and industry.

Big 2025 also places the highest demands on training programs: In addition to technical know-how, talented individuals must also possess competencies in ethical AI development and sustainable business development. The networking of stakeholders from universities, research centers, and companies creates a unique ecosystem that aims to secure innovation leadership in Europe in the long term. As a result, young founders are establishing contacts with established companies such as Allianz and Bosch, which are increasingly opening their innovation programs to collaborative projects. New Spaces for Innovation: How Big 2025 Promotes Creative Encounters

Big 2025’s structure stands out for its innovative spatial concepts, which specifically encourage the exchange of new ideas. One example is interactive experience worlds such as “Die Deeptech sieht Big,” which is based on gaming experiences and multimedia installations. This combination of science, technology, and social impact makes innovation tangible for the general public and inspires participation in disruptive developments.

Another highlight is “Ampli | Big Media” – a central media hub that brings together prominent personalities and opinion leaders.
