About Us

Tamarack was founded in 2014 by Paul Rubens to support US- and Asia-based investment managers, running a range of hedged, long-only and private markets strategies, as they build relationships with institutional investors in North America.


Tamarack raises the profiles of emerging managers and niche strategies among professional allocators and helps facilitate investor due diligence.


Manager Capabilities

Hedge Funds

Tamarack works with single strategy managers, as well as specialist multi-manager strategies to access a range of hedge funds in the U.S., Greater China, Japan, India and elsewhere in Asia.

Japanese Growth Equity

We work with a Tokyo-based growth specialist for Japan long-only equity. Our manager leverages a deep research database built over decades covering Japanese growth companies and a rigorous on-going local research effort. The team seeks impact from research time spent by constructing concentrated, benchmark-agnostic portfolios.

non-profit/blended financE

Tamarack supports climate resiliency in the Greater Mekong Sub-region (Vietnam/Cambodia/Laos) through its representation on the Board of Thrive Networks/East Meets West Foundation and blended finance initiatives with regional lenders.
