Navigate uncertainty with confidence
​
I partner with leaders ready to step out of their comfort zones, reimagine what’s possible, and achieve breakthrough results. I create space for courageous conversations that shift mindsets, deepen trust and mobilize individuals.
My work supports organizations in strengthening leadership in uncertain times, building resilient, high-performing teams, and fostering high-impact cultures rooted in psychological safety and accountability.
My clients span diverse industries—from banking and insurance to consumer goods, pharmaceuticals, telecommunications, automotive, and luxury watchmaking.
Having lived in twelve cities across four continents, I bring cultural agility and a global mindset, speaking English, French, and Spanish fluently. I thrive in multicultural environments and help my clients do the same.
Above all, I am passionate about instilling courage in others, helping them embrace their most authentic selves and fulfill their highest potential.

"Sébastien has a very down-to-earth and practical approach. He quickly got to the heart of how our team works — and helped us see what needed to change. His style is direct but supportive. The results were clear right away: stronger communication, more ownership, and a real shift in how we show up as leaders."
