About

I'm Arun Asok, currently serving as the Program Director for Climate Finance at Rainier Climate. My career has been dedicated to the intersection of finance and global development, from managing impact funds in Singapore to leading private capital initiatives globally. I’m passionate about directing capital at scale toward underserved markets to create a more equitable future, particularly through the lens of climate and health. I’ve had the privilege of raising significant capital for the BUILD Fund and structuring complex blended finance vehicles that bridge the gap between commercial investment and social impact. I’m always looking to connect with mission-driven individuals and organizations working on sustainable development solutions, especially those exploring the nexus of climate, energy, and health. Whether you're navigating a career in impact or looking to collaborate on innovative financial structures, I'm happy to share what I've learned.

Opinions

  • Finance is a transformative power for driving systemic change rather than just a commercial end
  • In-person human collaboration has unique power for solving complex global issues
  • Climate financing must be linked to health outcomes and long-term maintenance, not just infrastructure
  • The '2 and 20' asset management model needs rethinking
