Adapting your communication style to your interlocutor’s profile to capture his or her attention or even better, to present with impact and be convincing, is not a topic you learn at school. Yet there are many professions where this “secret weapon” makes a difference. I discovered the “magic formulas” thanks to Eric De Cozar’s training.
Eric’s experience, his teaching methods, his kindness and openness are aimed to serve our progress: Thank you HARMODEAL!


Anne Catherine Rosenblatt
CEO Subteno

Last Tuesday I grew up suddenly! Through the negotiation training of Harmodeal, I understood how to behave in front of my clients and how to create value through negotiation. A win-win process that no longer makes me see this moment in a negative way!
I highly recommend Eric De Cozar, a professional expert in his field and extremely pedagogue!
Novice or experienced in sales or negotiation, we all must learn from him!


Sybille Bellamy Brown
CEO Araxes

I was unexperimented in sales and trade, but Eric provided me with me a method and gave some arguments/tips to improve my ability to engage and convince my customers.
His very human approach and attention helps adapting the technics to every personality. Putting it into practice through exercises makes training concrete.
Now I feel better equipped to understand my interlocutors, to lead a commercial conversation, to approach the pricing discussion with serenity.
Eric’s energy as well as his kindness and his permanent support are all strengths in this training.
I can only recommend his know-how that he adapts to each of our profiles and business structures, his generosity in teaching and his commitment to our companies.

Despite several years of experience in customer prospection, sales, negotiation and overall trade relationship, I felt the need to move to an even higher stage. In a dense, exciting training session, Eric shared his knowledge, adapted to the participants specific demands, to the needs of every participant and made us progress at our best. He was full of energy, genuinely interested in people and is a great professional.
If your business takes you to the sale or negotiation, I can only recommend that you boost your skills by calling to Eric, whether you are a novice or already experienced.
