Internal dedicated company training sessions
We can organize training sessions just for your company, in your premises or online. We call them "intra-company" sessions or "internal" training sessions. These sessions can be organized in your company's premises anywhere in the world, but if you prefer we can organize it in Paris, in our facility. You can contact us for rates and conditions regarding internal training sessions and we will get back to you with different options.

Inter-company training sessions, now online too
We organize several training sessions each year for people from different companies and industries, in English and in French. Because people from different companies can participate, we call them inter-company sessions. We organize these trainings in our facilities in Paris, and since the Covid-19 crisis we now also organize them online.
We adapt the format and the content of our trainings to offer you online learning, consisting of 2-hour sessions per day over several days.
For all our training courses being reprogrammed, contact us if you wish to be kept informed of the new dates
