French fintech WeeFin secures €25M to elevate sustainable finance and fuel expansion — TFN #FrenchFinance

WeeFin, a French sustainable fintech empowering financial institutions to manage their ESG strategies, has secured €25 million in fresh funding. The round, led by BlackFin Capital Partners alongside existing investors IRIS, Asterion Ventures, and Ring Capital, will accelerate WeeFin’s mission to raise the standards of sustainable finance while expanding its global footprint, particularly in the UK.

The capital injection will be used to enhance its platform with optimised data management and new modules, including an ESG performance attribution tool, as well as expand into new markets, focusing on the UK, Luxembourg, and Italy. The funding will also fuel the company’s traction to increase regulatory compliance support, ensuring financial institutions stay ahead of evolving sustainability regulations and grow its workforce, adding 100 new employees over the next three years.

Aims to reshape sustainable finance

Founded in 2021 by former banking and finance professionals – Grégoire Hug, Marion Aubert, and Guillaume Klech, WeeFin provides financial institutions with a SaaS platform that centralises ESG data, impact metrics, and climate strategies. With over 40 clients managing a staggering €6.9 trillion in assets, the company is a rising force in sustainable finance. Its client roster includes financial heavyweights such as Generali Asset Management, Caisse des Dépôts Asset Management, Groupe BPCE, and Malakoff Humanis.

WeeFin’s modular platform streamlines the ESG process such as handling data collection, regulatory updates, impact measurement, and sustainability reporting. This allows financial institutions to align their investment strategies with ambitious sustainability goals.

WeeFin’s success reflects the growing importance of sustainability in finance. In just two years, its international revenue has jumped from 0% to 30% of total sales, and Annual Recurring Revenue (ARR) has grown fivefold. The company’s decision to establish a London office underscores its commitment to international expansion and meeting the increasing demand for ESG-driven financial solutions.

What makes WeeFin stand out in sustainable fintech?

Sustainable finance is no longer a niche but a necessity. Financial institutions worldwide face pressure from investors, regulators, and stakeholders to integrate sustainability into their decision-making. WeeFin’s platform simplifies this complexity, providing clients with real-time insights, regulatory updates, and impact assessments, all in one place.

This commitment to innovation has earned WeeFin spots on Impact 120 by Mouvement Impact France (which identifies future impact unicorns) and the prestigious 2024 ESG Fintech 100 ranking.

What’s next for WeeFin?

With its fresh funding, a growing client base, and an ambitious roadmap, WeeFin is well-positioned to lead the next wave of sustainable finance innovation. As ESG considerations become critical drivers of investment decisions, WeeFin’s solutions will play a key role in helping financial institutions navigate the evolving landscape of sustainability. The future of finance is green and WeeFin is at the forefront of making it happen.

Julien Creuzé, Partner at BlackFin, and Chloé Novène, Investment Manager et BlackFin commented, “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. In a very short space of time, WeeFin has won over some of the world’s leading asset managers and achieved some very exciting international successes, particularly in the UK. At BlackFin, we share the founders’ vision to establish WeeFin as the leading ESG data management platform for large financial institutions and asset managers. We are looking forward to working with the teams and supporting them in this new phase of growth.”

Grégoire Hug, CEO and co-founder of WeeFin added, “With BlackFin Capital Partners as one of our investors, WeeFin has the support it needs to make a definitive impact in Europe. We have always been convinced that sustainability is an essential and differentiating strategic element for financial institutions.
