In this article, Harvey Koh, managing director at FSG, discusses the surge in impact investing and the urgent need, “…to help interested investors mobilize more catalytic capital for greater impact.” According to the GIIN’s 2020 Annual Impact Investor Survey, the impact investing sector has grown steadily to USD 715 billion in 2020. “We need to explain the why, what, and how of catalytic capital at a more granular level for different investor types”, writes Koh. This will help expand catalytic capital and move us closer to, “realizing the large-scale solutions that the world needs today.”
