ABOUT US
Luxinvest Capital Advisors S.A. is a Luxembourg-based boutique advisory firm specializing in sustainability-driven finance and corporate structuring. We focus on companies that deliver high-value environmental solutions while demonstrating strong commercial performance.
​
Our core areas of expertise:
​
-
Climate Tech Expansion & Local Economic Development
We assist climate tech companies in scaling their operations from Luxembourg—a strategic gateway to the EU market and a hub for innovation. By establishing a local presence, these companies contribute directly to Luxembourg’s economic diversification through job creation, innovative solutions, and added value to the national economy.
Our role goes beyond advisory: we help climate tech firms unlock growth by connecting them with key public and private stakeholders. This accelerates market entry, fosters collaboration, and amplifies impact both locally and internationally.
-
Sustainable Finance & Green Bonds
We support companies in raising green debt financing through the structuring of Green Bond issuances. This enables businesses to fund their growth while aligning with sustainable practices and investor expectations.
Luxembourg’s reputation as a global center for sustainable finance—bolstered by the Luxembourg Green Exchange (LGX)—makes it the ideal location for issuing and listing Green Bonds. [Discover more about LGX.]
At Luxinvest Capital Advisors, we guide our clients through the complexities of both climate technology development and sustainable finance. Our mission is to help them thrive in Luxembourg’s pro-business environment and advanced financial infrastructure, while actively contributing to the country’s long-term sustainable growth.
