About us

We are transformational infrastructure specialists dedicated to helping make the UN Sustainable Development Goals happen.

We believe that reaching these 17 ambitious targets is essential for the future of people and the planet by tackling climate change, building resilient communities and protecting the environment.

And we have the expertise and creativity to make a real impact. Our people are hands-on problem-solvers, focused on three impact areas – critical public services, sustainable mobility, and innovative low carbon solutions.

We deliver sustainable and resilient infrastructure over the long term, support and accelerate the development of innovative, ambitious and fast-growing SMEs involved in the ecological transition.

Investing responsibly has the power to build economic growth and dramatically improve people’s lives. It’s why we promise long-term commitment to every project and every community we serve. For today’s world, tomorrow’s progress and the good of future generations.

Who we are
We are a Benefit Corporation (B Corp) and an asset manager. As a B Corp we’ve made a legal commitment to social and environmental sustainability, equal to our financial commitment.

Where we work

We help countries in both developed and emerging markets across Europe, Africa and the Americas. By creating new and essential infrastructure and replacing ageing services, we hope to improve the quality of people’s lives. Founded in Paris in 2005, we now have ten offices and over 368 employees around the world, and our assets have created over 250,000 direct and indirect jobs (learn more).

Our impact areas

We are focused on delivering impact in three areas: Critical public services, Sustainable mobility, and Innovative low carbon solutions. Our integrated approach to investment ensures we can maximise economical, environmental and social benefit across every project.

Our initiatives

We believe we can make a bigger impact if we share our knowledge and experience with academic institutions, non-profit groups, entrepreneurs and investors.

We are particularly keen to be involved in initiatives that support sustainable development goals at a grassroots level. In 2015 we established our corporate endowment fund that further strengthens our ability to support impactful assets on gender equality and biodiversity.

Our academic partnerships include:


Entrepreneurship and youth engagement support includes:
  • Working with the Entrepreneurs de la Cité Foundation since 2008 on its valuable work fighting exclusion of disadvantaged communities in France
  • Backing the ADOS association to help develop career opportunities for young people from the disadvantaged neighbourhoods of Paris
  • Identifying and increasing the potential of inclusive leaders with associations including Empow’Her , Bond’Innov , Ashoka


Other initiatives include:


               – Certify the sustainability of infrastructure projects with the FAST-Infra Sustainable Infrastructure Label®.

              – Increase the volume of bankable projects via the FAST-Infra Platform

  • Meridiam initiated the Long-Term Infrastructure Investor Association (LTIIA) with a group of global institutional investors, to form an industry association for long-term investing in infrastructure. This independent organization, led by investors, aims at increasing the knowledge base to encourage quality sustainable investment in infrastructure. A key component includes sharing and promoting ESG best practices between investors.
