Our Story
With over two decades of experience studying financial markets – as a portfolio manager at some of the world’s largest financial institutions and most recently as a professor at Columbia Business School – our founder, Dr. Harry Mamaysky, was frequently approached by friends and family seeking investing advice.
Over the years, Harry realized that individual investors often lack access to the kinds of resources and strategies used by sophisticated financial institutions.
“Individual investors often end up investing on their own and putting their money into funds that charge high fees that negatively impact returns.”*
Harry created QuantStreet to offer clients sophisticated advice, reasonable fees, and a thoughtful approach to risk.

With extensive experience in law, compliance, and organizational management, QuantStreet’s co-founder, Isaac Mamaysky, had been one of the people asking Harry for investing advice.
“To non-professional investors, making good investing decisions can feel a bit like walking in the dark. Research actually shows that individual investors often buy when they should sell, sell when they should buy, and otherwise don’t make the same kinds of decisions as professional money managers.”*
Isaac partnered with Harry to launch QuantStreet because to help clients navigate the challenges of investing.

With Harry as our Chief Investment Officer and Head of Research, and Isaac as our Chief Operating Officer and Head of Compliance, QuantStreet was born. Our goal is to help investors build wealth and achieve their financial goals, and to empower other asset managers to make rigorous, quantitatively-driven investment decisions for their own clients.
Individuals can engage us for custom portfolio management or personalized financial planning, or they can invest in a defined QuantStreet strategy. Asset managers can subscribe to our model portfolios or retain us for consulting or OCIO services.
We deeply appreciate that trust that clients place in us. Our mission is to help clients achieve their goals by making wise investment decisions and carefully managing risk.
