The VIVA TECHNOLOGY is the leading event for start-ups and innovation players in France. The eighth edition will take place from 22 to 25 May 2024 at the Paris Expo Porte de Versailles.


More than 100 German and French start-ups from the fields of Artificial Intelligence, Industry 4.0, Health Tec, Sustainable Energy Solutions, New Materials and Surfaces, Data Solutions, Entertainment and Education, CyberSecurity, Mobility and Enterprise Solutions, among others, will present themselves in the joint pavilion together with:

  • the Karlsruhe Institute of Technology (KIT),
  • the Technical University of Munich (TUM),
  • the Franco-German Centre for Artificial Intelligence (DFKI),
  • the De Hub Digital Ecosystems,
  • the Franco-German Chamber of Industry and Commerce (AHK),
  • the Franco-German University (DFH/UFA)

as well as organisations from the German states of North Rhine-Westphalia and Saarland, in close cooperation with the Mines Telecom Institute.

Effectively reducing CO2 emissions: Using the production of renewable natural gas to reduce CO2 emissions is the goal of Turn2X. Electrolysis uses renewable energy to produce hydrogen from water and then methane – the main component of biogas – by adding climate-neutral CO2, for example from biomass combustion. While this basic biogas production process is not new, the unique feature of Turn2X’s patented methanation reactor is that it can operate in the face of intermittent renewable energy supplies. This makes Turn2X’s approach a scalable, cost-effective and sustainable solution.


Phytonics has developed a broadband, angle-independent anti-reflective coating with outstanding light-harvesting properties. It is inspired by plant surfaces and improves the yield of solar modules by up to ten percent. The aim is to make a significant contribution to the energy revolution.

The acceptance of software in the construction, property and maintenance industries is very low, especially among those who work on site. The reasons for this are simple. The people involved want to build software, not operate it. On the part of the coordinator (e.g. site manager), this leads to forced, spontaneous and uncoordinated requests via chat, email and telephone, resulting in absolutely chaotic communication.

Valoon addresses this issue by combining the benefits of project management software, such as structure and clarity, with the acceptance and simplicity of messengers. This is achieved by allowing the coordinator to communicate with participants via Valoon, while workers continue to use the messengers they are familiar with, such as WhatsApp.


AvoLingo is revolutionising language education by using AI to connect teachers and students, making education more affordable and accessible to everyone. Their platform enables contact through AI avatars of teachers. These avatars interact with students, adapting to their individual learning style, pace and needs, and guiding them through the teacher’s material. This personalised approach provides each student with tailored language learning support.


RevoAI develops software that enables organisations to exploit the full potential of digital twins. One application is testing in development, which can reduce costs by a factor of more than 1000.


Revyve wants to enable climate-neutral mobility on the water. The team is developing climate-neutral hydrogen engines for the marine sector, known as Hydrogen Internal Combustion Engines (H2ICE), which burn hydrogen. Hydrogen engines are a cost-effective and robust alternative to conventional CO2-free propulsion systems such as batteries or fuel cells.
