Laure, Head of HR

Before starting the course, I thought that Negotiation was an art reserved for an elite and that I would never be able to do it. In fact, I was wrong. With the right techniques, I discovered that I could face any negotiation situation without the apprehension I used to have.

In the training course, all the techniques are explained very clearly. For each one, the trainers share their experience, which enabled me to identify with some of the situations I encounter.

I realized that negotiation can be learned, and that it's not a gift but a skill to be acquired.

Thanks to the method, I've already saved over 10,000 Euros on my first negotiation. I still can't believe it.

Sophie, Head of Procurement

I was looking for a negotiation method that would cover all the negotiation situations I might encounter. I had considered signing up for a course at a university, but the fees always put me off and I didn't want to invest that kind of money in training.

What impressed me most about the method was the ease with which the concepts presented were assimilated.

I took the online course and have been applying it on a daily basis ever since. Above all, I've retained 5 techniques that correspond perfectly to my personality and enable me to come out on top in all my negotiations.

Mathieu, Head of PM

The course has transformed my interactions with my friends. It sounds silly to say this, but before I took the course, I thought that always accepting what was asked of me would win me the sympathy of others. I realize that this is not the case. On the contrary, it more often than not aroused animosity because I was perceived as weak.

Since I've been using the Inness method, even with my friends, my contacts have told me that discussions are more pleasant and everyone benefits.

The other advantage of online training is that I've been able to progress at my own pace. The lessons already reviewed are available online 24/24. The 21-day challenge also pushed me to take small steps every day to achieve a big result in the end.

    Tout à fait. La totalité de votre contenu restera accessible en illimité, de façon à ce que vous puissiez revoir chaque leçon autant de fois que vous le souhaiterez.
  • J'aimerais apprendre à négocier, mais je doute d'avoir le niveau… Que faut-il savoir pour participer à cette formation à la négociation ?
    Absolument rien. Que vous soyez un négociateur occasionnel, professionnel ou bien encore un parfait débutant, vous êtes au bon endroit. Tout ce dont vous avez besoin, c'est votre envie d'apprendre.
  • Comment serais-je certain que cette formation est véritablement efficace au moment de m'engager ?
