Founded in 2025 in Paris, we are a growing ecosystem of 20+ professionals located at the intersection of strategy, finance, and sustainability.

Our ambition is clear

Help shift the economy from an extractive model to a regenerative one — by positioning finance as a strategic accelerator of that transition.
This translates into:
- Acting as a lab for regenerative finance innovation
- Developing strategies and frameworks that move beyond compliance into transformation
- Cultivating systemic thinking and cross-sector collaboration
- Training the next generation of finance professionals to work with purpose and vision
Weastem is expanding — and we are currently seeking Engagement managers ready to play a key role in delivering and shaping missions that matter.
