Co-founded by Emmanuel Parmentier and Imène Maharzi, with Charlotte Salmon newly appointed as Partner, WEASTEM emerges from over 15 years of hands-on experience in strategy consulting and sustainable finance — and from a clear observation:
👉 The sustainable finance model built in the 2010s has reached its limits.
With a 20-person team and a systemic view of finance, Weastem works alongside investors to shape expansion and investment strategies adapted to the New Climate Era.
👉 The model of incremental ESG — built on marginal adjustments and limited scope — no longer holds.
A sustainability approach that avoids revisiting core business models or reallocating capital is no longer sufficient.
Weastem was created to provide innovative, actionable solutions across the financial value chain — from banks, insurers, pension funds and family offices to asset managers and corporates — helping leaders navigate uncertainty and reframe value in light of planetary and societal constraints.
🔍 Beyond silos
Sustainability, adaptation, and transition management can no longer be confined to specialists. These questions are bound to inform strategy, operations and investment decisions across the entire financial ecosystem.
In the New Climate Era, finance is expected to serve an economy increasingly centered on essential needs and long-term resilience — ultimately contributing to the regeneration of the living.
This calls for new tools, new models, and above all, new forms of cooperation.
⭐ What sets Weastem apart
✔️ A systemic vision of finance and its role in the New Climate Era
✔️ A distinctive model and tailored offering, with 3 core services focused on the needs of CEOs, CSOs, and deal teams
✔️ Cooperation at the core, combining a seasoned in-house team with a growing European expert network
✔️ A dynamic thinking engine, designed to deliver ongoing strategic clarity, fresh insights, and high-level guidance for clients facing complex transitions
We catalyse capital toward solution companies — businesses with products and services that enable climate and societal progress.
At the same time, we support the broader economy — the one we all rely on — to evolve, adapt, and remain investable in the face of systemic risk.
“Only through cooperation can we begin to meet the immense challenges of the New Climate Era. By bringing together finance, strategy, and innovation, we are laying the groundwork for a deep and lasting transformation.”
If this resonates with you, we'd love to connect!
