ABOUT US
Who we are
At Castalia we use our knowledge, skills and experience to question and redefine how the infrastructure challenges of the world are solved.
We are experts in the finance, economics, law, and policy of infrastructure, natural resources and social service provision. We are passionate about finding solutions to the world’s most complex infrastructure problems in those fields, knowing that in doing so we can make the world a better place.
Founded in 1980 by Roland Leroy in Paris, Castalia was built from the start around innovative thinking on the organization of public services. Our portfolio of work speaks for itself. Over the past 4 decades we have pioneered public private partnerships in infrastructure on a global scale, we developed the framework that will help utilities to turn themselves around, and we are now redefining the fiscal management of infrastructure.
Since 1980 we have grown in staff numbers and global presence. We have over 50 members of staff, and offices in: Washington DC, USA; Auckland, New Zealand; Wellington, New Zealand; Sydney, Australia; Bogotá, Colombia; and Paris, France.
Castalia is the trusted advisor of corporations, utilities, governments, international agencies and infrastructure investors around the world. We solve complex, strategic assignments and deliver sustainable, measurable results.
OUR MISSION
We apply smart thinking and analytical rigor to solve the world’s biggest infrastructure, resource, and policy challenges
What we value
Integrity
We treat our clients and each other with respect. We are honest and say what we mean. We encourage open debate, and if we think someone is making a mistake, we say so, tactfully. We do not play political games. Once a decision is made, we are committed to following through.
Intelligence
We are thoughtful. We understand the value of experience, but we also question traditional approaches, looking for better, smarter ways to do things. We need to understand and be able to justify the way things are done – the answer ‘we’ve always done it that way’ is not enough.
Quality
We are committed to excellence. We always do the best we can. If our best is not outstanding, we find ways to improve. We approach everything we do with rigor and passion. That’s how we make sure that every output and interaction is of the highest standard.
Results
We are not interested in analysis for its own sake. Satisfaction comes when our intelligence and experience can be applied to achieve practical results. We aim to help our clients achieve results.
