Client testimonials
What our clients say about us.
“I had the pleasure of working with Olivier Janin on the ICPC project – a cross-industry initiative focused on the circular economy in the plastics sector. Over two years, Olivier led the project with remarkable structure, diplomacy, and a strong solution-oriented mindset, even within a complex environment involving market peers and limited availability of key stakeholders. His calm, analytical approach and highly professional communication were key in driving the project close to its launch phase. I truly valued his expertise and the excellent collaboration both professionally and personally.“
“As part of the transformation of IGM Resins as CEO, I have asked Olivier to join us to address our need for a robust commercial excellence platform, a lean marketing organisation accelerating the rollout of our innovations and to develop our sustainability strategy as an element of the marketing mix.
Over two years, Olivier led these assignments with structure, energy, and a strong ownership towards results, in line with the transformation agenda I set for the company. His experience in leading business transformation made him credible across the Excom for a rapid buy-in within all departments. His customer centricity, relationship building and highly professional communication were key in delivering on the objectives. I truly valued his blending in our Excom team and the trust we developed both professionally and personally.”
