Sustainability-focused fintech WeeFin has raised €25 million in a Series B funding round led by Blackfin Capital Partners. Founded in 2021 by Grégoire Hug, Marion Aubert, and Guillaume Klech, WeeFin offers a SaaS platform that helps financial institutions centralize and manage ESG, impact, and climate risk data.
With 40+ customers across Europe, including Generali Asset Management, Caisse des Dépôts Asset Management, Groupe BPCE, and Malakoff Humanis, WeeFin supports firms managing a combined €6.9 trillion in Assets under Management (AuM).
The company has experienced rapid growth, with 30% of total revenue now coming from international sales—up from 0% just two years ago—and Annual Recurring Revenue (ARR) increasing fivefold in the same period. As part of its European expansion, WeeFin is entering Luxembourg and Italy and establishing a UK office. The company has also doubled its workforce in two years and plans to hire 100+ new employees over the next three years.
Grégoire Hug, CEO and co-founder of WeeFin, emphasizes the strategic importance of ESG in finance:
“Sustainability is an essential and differentiating element for financial institutions. This Series B confirms our vision, validates our clients’ trust, and reinforces the relevance of our platform in tackling sustainability challenges at scale.”
