Sirio Capital Partners is an advisory and investment firm dedicated to strengthening the next generation of emerging market fund managers.

Our mission is clear: to help fund managers build, grow, and perform — delivering both financial results and lasting impact.

Our philosophy draws inspiration from Mastering Emerging Markets Funds — a forthcoming book by Jeroen Harteveld — which explores the patterns and principles behind exceptional fund managers (available here) . The book’s insights form part of our foundation: a belief that mastery in emerging markets requires not only performance but also patience, adaptability, and purpose.

At Sirio Capital Partners, we apply these same principles in practice — identifying, partnering with, and investing in the next generation of fund managers shaping the future of global finance. 

We back those who build the capital ecosystems of tomorrow.

What sets SIRIO apart is the combination of perspective and practice. Our guidance is drawn from over 20 years of investing, managing, and studying exceptional emerging market funds — and the pattern behind success.

What We Do

Fund Managers (GPs) — from first-time teams to established firms preparing new vintages.
We help sharpen investment strategy, strengthen investor relations, and build organizations designed for performance.

Institutional and Private Investors (LPs) — from development finance institutions to family offices.
We offer practical frameworks to assess, select, and support high-performing GPs in fast-growing markets and selectively invest in those managers set up for outsized impact and commercial returns.

Global Focus

From our base in Amsterdam, The Netherlands, we work globally — covering funds active in Africa, Latin America, the Middle East, and Asia.

Our role is to support ambitious fund managers turn vision into a fund strategy that attract capital, perform, and create impact.
