Anchored in Europe, with offices in London and Zurich, and supported by a growing platform in Asia based in Singapore, the team brings deep expertise and a longstanding track record across energy transition themes and risk-return profiles, investing across the capital stack from senior-secured credit to value-add equity. The integrated platform applies a proactive approach to risk management and value creation that systematically integrates ESG considerations and delivers measurable decarbonisation impact.
