SWITZERLAND – September 18, 2023 – Quantis, leading environmental sustainability consulting firm, today announces the appointment of its new Managing Director and Global Leader Allon Zeitoun. Based in France, Zeitoun will lead the Quantis team as it continues its path to align the economy with planetary boundaries.

I’m excited to start working with our people and clients to achieve this goal. The evolution is already taking place, but the planet needs us to move faster – and we’re here to meet the challenge.”

Zeitoun brings more than a decade of experience in strategy consulting, including eight years spent at Quantis’ parent company, Boston Consulting Group (BCG), where he advised consumer goods and healthcare companies on large scale business transformation.
