Testimonials

What are our clients saying about us?

“In the process of designing our fund, Raison was instrumental in helping us figure out how to make Article 9 operational, balancing pragmatism and compliance with the spirit of SFDR. We now work with Raison on all our impact due diligence projects – they are quick to get on the ball and work independently, while understanding and respecting the need to control time spend. As I see as more and more funds operating in this space, it is clear to me that Raison Consulting is absolutely best-in-class.”

“Raison supported Stiesdal in carrying out our first double materiality assessment and in articulating our sustainability ambitions and roadmap. Raison has been instrumental in structuring and documenting our sustainability efforts in line with the latest legislation, while keeping a keen eye on proportionality and translating complex legislation into actionable plans. We recommend Raison for their vast knowledge of the sustainability legislative landscape, complemented by a pragmatic approach to enabling compliance and impact.”

“Working with Raison on our ESG initiative has been a transformative experience for us. Their expertise and dedication significantly helped us to align our business with best practices and industry standards.”
