When a company questions its business model, considers leaving a model at the end of its lifespan, or creating new sustainable growth drivers, two challenges arise: which model to build for tomorrow? And how to make it happen?

To answer this question, I created Celsious, a conscious innovation agency that helps organizations transform themselves to create their best future.

With an entrepreneurial DNA, we work with each company on their main challenges, design innovative solutions to them and drive their implementation as if they were our own startup.

Convinced that social and environmental responsibility is a great driver for value creation, we are committed to building projects designed for the long term and delivering a positive impact for current employees and customers as well as for future generations.

As a B Leader, I assist companies in assessing their impact on employees, community, and environment, identify drivers for improvement and support their implementation.

An engineer from INSA Lyon and a graduate of HEC Paris business school, I have acquired strong experience in development, business transformation, and innovative project management.

After working in sustainable development consulting, I took charge of the innovation department at Veolia Environnement. I led the implementation of partnerships with start-ups in the water, energy, transport and waste sectors with the goal to improve the company’s positive impact. I then managed a vast internal transformation project at Veolia Water.

As an entrepreneur, I have coached more than 50 entrepreneurial or intrapreneurial projects and created several companies myself:

- Copines de Voyage, a collaborative travel agency allowing single women to meet and travel together
- FWE, an outsourced financing offer for environmental infrastructure

I am a lecturer for the HEC Paris’ master degree in Entrepreneurship and coach for the Led By Her women’s entrepreneurship program.
