YIS Capital’s investments are anchored by the philosophy that market inefficiencies and related opportunities exist in certain asset classes. To realize this potential YIS seeks to partner with those investment managers or business operators with an identifiable “edge.” Finally, this partnership must include a strong alignment of incentives that minimizes — if not eliminates — the principal/agent conflict.

Who We Are


YIS is led by Jeff Greenstein who has been actively investing in alternative investment strategies for over 30 years for his portfolio and on behalf of leading institutional and private clients worldwide.

What We Offer


YIS believes the best investment managers and business operators can and should be selective in who they partner with.

Our Focus


YIS Capital has no predefined asset allocation, and instead seeks to build a diversified portfolio of idiosyncratic opportunistic investments.
