Immerse yourself in the innovative world of Big 2025

Every year, the world of innovation and entrepreneurship converges at Big, the flagship event organized by Bpifrance, which brings together the largest European business ecosystem. This eleventh edition, scheduled for September 23, 2025, at the Accor Arena in Paris, promises to be a true immersion into the ongoing changes, combining science, advanced technologies, and major societal concerns. Under the powerful theme of « truth, » Big 2025 transcends traditional trade shows to offer a unique platform where leaders, researchers, students, and innovators confront ideas, experiences, and ambitions. This edition takes place at the heart of a context where scientific truth is becoming a valuable compass in the face of complex global challenges – an essential framework for understanding why and how companies, driven by Deeptech, artificial intelligence, and the quest for sustainable reindustrialization, are reinventing their future. Innovation Drivers at Big 2025: Reindustrialization and AI at the Heart of Economic Challenges

In a world marked by major disruptions, reindustrialization is now positioned as an essential pillar for European economies. This dynamic is at the center of the debates and conferences at Big 2025. The event highlights French initiatives led in particular by iconic players such as La French Tech and OVHcloud, which embody the alliance between technological innovation and industrial sovereignty. The revitalization of industrial sectors is essential in the context of international competitiveness exacerbated by fragmented globalization and geopolitical tensions.

Through dedicated meetings, visitors can discover how cutting-edge technologies, particularly those from Inria laboratories, will put Deep Tech in the spotlight. This scientific and experimental approach confirms the central role of facts and data in an economy dominated by artificial intelligence. Demonstrations, interactive workshops, and thematic booths allow entrepreneurs to understand how to integrate generative AI into their processes to accelerate productivity, customer personalization, and optimize the supply chain. Le Wagon, a recognized training platform, also offers sessions to equip new talent to face these technological changes, preparing them to meet the specific needs of a rapidly expanding Industry 4.0.

Reindustrialization, coupled with digital transformation, is not just a simple trend but a true economic revolution, driven in particular by targeted funding from Bpifrance, which facilitates the scaling up of ambitious projects. This public-private support is one of the secrets to the continued success of this gathering, which brings together this expertise. The meeting with corporate leaders and innovative SMEs reveals a strong trend: the alliance between artisanal know-how, often intangible, and advanced manufacturing processes, underpinned by data, to meet today’s environmental and technological challenges.

Finally, this industrial panorama fuels a broader reflection on the place of French and European companies in a global economy that is as fragmented as it is interconnected, as well as on how innovation, like the ecosystems fostered by Cap Digital and NUMA, can build bridges between territories, sectors, and generations. These dynamics will be highlighted through the proposed thematic tours, which provide an opportunity to immerse yourself in strategic issues that are critical for economic players engaged in this journey.

The 2025 edition of Big places particular emphasis on the essential role of

artificial intelligencein the digital transformation of businesses. This year, a space entirely dedicated to the AI of Joywill offer the public the opportunity to demystify this technology, which is evolving with unprecedented intensity. Workshops and roundtable discussions will help visitors explore generative AI not only as a tool for innovation but also as a lever for solving human, organizational, and economic challenges. Innovators and experts from diverse backgrounds, from Doctolib to Viva Technology, demonstrate how AI is becoming part of everyday business while also raising ethical and responsible questions. For example, digital health solutions designed to improve access, prevention, and medical monitoring will be at the heart of discussions in the Health track. The concrete case of Doctolib perfectly illustrates how digital innovation addresses concrete challenges by making the healthcare pathway more seamless and accessible to all.

Big 2025 not only showcases technologies; it also provides a forum for debate where essential doubts and reflections around data and its processing can be expressed. Without denying the issues of confidentiality and regulation, this edition affirms the superiority of scientific truth, supported by rigorous statistics and experiments, over vague opinions or misinformation. This commitment to rigor is reflected in the quality of the speakers, featuring some of the most recognized figures in their fields, who place innovation in a human and responsible perspective.

Furthermore, synergies between stakeholders such as Station F and Le Wagon illustrate this desire to support digital transformation through training and skills sharing. The goal is to collectively build augmented intelligence to foster the emergence of solutions adapted to future challenges. This commitment to training underscores a fundamental aspect: the power of innovation lies in the human being, the person who leads a project, develops an idea, and innovates to create meaning. French Tech and Innovation Ecosystems: Catalysts for Growth at Big 2025 The strength of Big 2025 also lies in its ability to unite innovation ecosystems, of which French Tech is the major driving force. This network, a driving force of economic growth and job creation in France, is distinguished by a network of key players gathered at the show: startups, incubators, investors, and public institutions, all driven by the desire to bring ambitious projects to fruition both nationally and internationally.

Particular attention is paid to the emergence of deep tech, which combines applied science and industrial ambitions to open up unprecedented perspectives. The close partnership with research centers like Inria fuels this dynamic by making fundamental knowledge available. These scientific advances come to life in innovative spaces, where prototypes can be tested in 360 degrees – a concrete example of how Big stands out from traditional forums. Furthermore, the harmonious coexistence of traditional players with new generations of business creators, whether supported by recognized training programs such as Le Wagon or stimulated by clusters like Cap Digital, fosters a fully integrated ecosystem. This cross-functionality of skills and diversity of profiles contributes to a unique ability to adapt to the demands of a globalized and highly technological market.

There is also a renewed focus on international development, with strategic partnerships at the European and global levels that encourage exchanges, cooperation, and exports. Roundtable discussions devoted to these issues highlight innovative territorial strategies, consistent with the objectives of reindustrialization and digital sovereignty, while ensuring competitiveness.

This collaborative infrastructure represents a major lever for business founders and buyers attending Big 2025, enabling them to discover investment opportunities, available training, and, above all, the essential network needed to grow their projects. Connections are forged in an environment that is both professional and friendly, fostering the exchange of cross-disciplinary expertise. This excitement reinforces Big’s position as a key catalyst for French economic renewal.

Health and Sustainable Mobility: Key Themes at Big 2025 for a Future Leader

Taking into account major environmental and social challenges remains at the heart of Big 2025’s discussions. With this in mind, the Health track offers an immersion into innovations that combine digital technologies and medicine, driven in particular by pioneering players such as Doctolib and deeptech startups. The focus is on prevention, medical data management, and also on quality of life at work for companies seeking to better reconcile economic performance and employee well-being. Another major program, dedicated to sustainable mobility, focuses on the humanistic and responsible solutions that will evolve in the coming years. Industrial innovation takes on its full meaning here, with demonstrations of advanced technologies aimed at reducing carbon footprints and encouraging safer and smarter modes of travel. The ambition is to make these solutions accessible on a large scale, to increase efficiency while preserving natural resources.

The discussions also address the essential issue of societal transformations, particularly through the impact of these technological innovations on territories and lifestyles. Testimonies from entrepreneurs and political leaders highlight the challenges of establishing a sustainable balance between economic growth, ecological transition, and social justice.

This responsible dimension is also reflected in the new « À table! » spaces, a food court entirely dedicated to informal exchanges that allows for discussions to continue in a friendly setting. These spaces encourage cooperation and conviviality, essential factors for driving high-impact projects. Big 2025 thus demonstrates that scientific truth must also be accompanied by social truth, ensuring that innovation truly benefits the greatest number of people. To delve deeper into housing and sustainable urban planning issues, particularly in large cities, it is also possible to draw inspiration from additional online resources such as
