About Us


GEG Tech’s mission is to design and provide cutting-edge vectorization and gene editing solutions, to help private and public research laboratories meet their innovation challenges.

Our core area of expertise is the design of advanced vectorization systems based on lentiviral technologies, where we hold a world-class know-how. From there, we regularly extend the range of our products and services to meet our Client’s needs.


GEG Tech has been founded in 2013 in Paris, France. Our R&D team mostly originated from cutting-edge research laboratories (incl. CNRS, the leading French research institution, and the Riken Institute from Japan), where we cumulate more than 15 years experience in pionneering research on advanced vectorization systems.

In 2014 we decided to switch to an open innovation model: instead of focusing exclusively on internal R&D projects, why not sharing our technologies and expertise to help other scientific teams meet their innovation challenges?

Launching an open innovation strategy required a fundamental change in the way we worked. We first had to work on R&D to adapt our technology to a variety of innovation contexts. In parallel, we designed an online platform to transparently share hundreds of vector technologies, as well as prices and other relevant data. The GEG Tech platform now offers more than 5’000 vectorization systems. Actually not enough, since many clients have specific requirements outside the catalog. Open innovation also involves sharing insights and methods to enhance our client’s innovation performance.

GEG Tech laboratory is located in the heart of Paris-area scientific hub (plateau de Saclay), in the François-Hyafil R&D center. Our R&D site (certified ISO 14 001) benefit from a complete set of state-of-the-art infrastructure and equipment (incl. biosafety levels 2 and 3 labs, as well as animal facilities).


GEG Tech R&D team is focused on innovation in gene transfer tools and constantly innovate to improve lentiviral vector features, capabilities and safety.

We aim at creating new tools which take every advantage of the lentivirus biology:
Integration-Deficient lentiviral vectors, Reverse-Transcriptase-Deficient Lentiviral Vectors (or mRNA lentiviral vectors) for a fully transient gene transfer, pseudotyping (VSV- or Mokola- pseudotyped lentiviral vectors to enhance the specificity toward your target cells).


For the last 15 years, the GEG Tech R&D team has been gaining experience in the field of lentiviral vectors through production of thousands of stocks, for multiple customers, various purposes and a wide range of R&D fields.

GEG Tech engages its knowhow and skills to the benefit of your R&D:

  • to make your project research efficient
  • to answer relevant questions in the most efficient way
  • to identify bottlenecks and provide original solutions
  • to optimize your resources and productivity


Thanks to our production methods, based on transient transfection instead of a stable producer cell line, each element can be modified at will to design the perfect vector for your specific needs and R&D objectives:

  • Cell targeting: choose a specific envelope to modulate the transduction or a specific promoter to determine in which cell the transgene is expressed
  • Gene expression kinetic and duration
  • Concentration of the particles
