As environmental, social, and governance (ESG) requirements increase across the finance industry, digital platforms that help institutions manage sustainability-related data are gaining traction. WeeFin, a fintech company focused on ESG data services, has secured €25 million in fresh funding to drive its strategic expansion and bolster its software offering. The round, led by BlackFin Capital Partners and joined by IRIS, Asterion Ventures, and Ring Capital, brings the company’s total capital raised to more than €34 million. The funding signals growing interest from investors in tools that enable financial firms to manage regulatory and impact-driven requirements efficiently.
WeeFin had previously raised undisclosed backing during its Series A phase and has since shown steady growth, evidenced by a fivefold increase in Annual Recurring Revenue (ARR) and international business now contributing 30% to overall revenue. Earlier reports had focused on the product’s technical capabilities, but not on the rapid revenue and geographic expansion now highlighted. The company’s scaling strategy appears to be more aggressive than initially indicated, with recent market entries in Luxembourg, Italy, and the United Kingdom.
What Does WeeFin Offer Financial Institutions?
Established in 2021 by Grégoire Hug, Marion Aubert, and Guillaume Klech, WeeFin offers a SaaS platform tailored for financial institutions managing ESG, climate, and sustainability data. The software platform integrates and centralizes complex and fragmented datasets that financial asset managers need to meet compliance and sustainability goals. Clients using the service include Generali Asset Management, Groupe BPCE, Malakoff Humanis, and Caisse des Dépôts Asset Management, indicating traction with large-scale users in the field.
The company positions its product as a response to the operational challenges financial firms face when implementing ESG strategies across diverse systems. The platform is built to scale with the needs of these institutions and to adapt to changing regulatory frameworks, especially in the European Union’s evolving sustainability landscape.
How Will the New Capital Be Utilized?
WeeFin intends to strengthen its product capabilities and accelerate its international expansion using the newly raised funds. It has already opened a branch in the United Kingdom and signed new clients in Luxembourg and Italy. Plans for further hiring include onboarding over 100 new employees within the next three years, doubling down on talent acquisition to support growth.
Julien Creuzé, Partner at BlackFin, and Chloé Novène, Investment Manager at BlackFin, commented on the decision to lead the round:
“We have been following WeeFin since its inception and have been particularly impressed by the ability of its management team to execute its ambitious vision. At BlackFin, we share the founders’ vision to establish WeeFin as the leading ESG data management platform for large financial institutions and asset managers.”
WeeFin’s CEO and co-founder, Grégoire Hug, also expressed confidence in the company’s direction:
“We have always been convinced that sustainability is an essential and differentiating strategic element for financial institutions. This Series B not only confirms this vision, but also validates our clients’ trust and the relevance of our platform, which enables them to address their challenges at scale.”
WeeFin’s focus on ESG data centralization reflects broader trends in financial regulation and investor expectations. With multiple jurisdictions requiring transparent ESG reporting, the demand for platforms capable of harmonizing this information is rising. While the company is currently focused on Europe, the strategic framework it is building — scalable software, multilingual support, and modular reporting features — may allow it to compete in global markets should it decide to expand further. The hiring strategy and geographic outreach suggest this may be on the agenda. For financial institutions, the ability to demonstrate ESG compliance effectively without overhauling legacy systems could make platforms like WeeFin’s an operational necessity.
