About Céleste

An engineer-manager by training, I support French and international companies in their transformation towards a business model compatible with planetary limits, with a global approach combining strategy, governance, and human mobilization. Today, I wish to contribute to the momentum of organizations in the Lyon region that want to go beyond intention, to profoundly evolve their model towards greater robustness and a positive impact business model.

My skills:

- Transformation steering and change management: Building roadmaps aligned with regulatory frameworks, structuring governance, defining new performance benchmarks.

- Evolution of offerings and sustainable innovation: Support for reinventing products, services, and uses to meet the narratives of sobriety and functionality. Support for ideation and implementation of projects serving the transformation plan.

- Ecosystem mobilization: Partners, clients, suppliers, territories. Weaving a collective dynamic that strengthens interdependencies rather than oppositions.

- Driving internal transformation: Mobilizing teams around a clear vision, inspiring narratives, and concrete mechanisms (training, workshops, highlights, ...).

- Sustainability labeling and reporting: Support in external labeling processes (Mission-Driven Company, B Corp) and consolidation of sustainability reports.
