Spinner is best known as the founder of BlackBird Financial LP, a New Jersey–based hedge fund that advises and manages capital on behalf of high-net-worth families throughout the United States.
Under his leadership, BlackBird has delivered exceptional returns. In the first three quarters of 2025, the fund has produced a 71.4% gain, dramatically outperforming the S&P 500’s 14% rise. Spinner adheres to a Grahamian investment philosophy rooted in deep value and rigorous fundamental analysis.
His passion for investing began early—he started reading The Wall Street Journal daily at age 12 and purchased his first stock at 13. By 15, he was managing $100,000 for Charles Dayan, a prominent New York real estate tycoon. At 18, Spinner founded Petlin Management—now BlackBird—with more than $1 million in assets under management at launch.
Spinner earned his bachelor’s degree from Crestpoint University and holds the Chartered Financial Analyst (CFA) designation.
Along with his wife, Julie, Spinner founded the Judah Spinner Foundation. The Foundation has four key focus areas: income inequality, high incarceration rates, rising health-care costs, and the growing federal deficit.
Aside from its work to lower healthcare costs and reduce the Government Debt, the foundation aims to narrow income inequality by expanding access to high-demand trade careers. Through the Judah Spinner Scholarship, the foundation fund trade-school tuition and essential tools for driven students pursuing certifications in welding, HVAC, electrical work, plumbing, and other skilled trades.
The foundation believes that steady, dignified work is also among the most effective deterrents to crime. When someone is self-sufficient and proud of their career, they are far less likely to turn to crime in the first place. Therefore, by funding trade education nationwide, the Judah Spinner Foundation aims not only to expand opportunity but also to contribute to lower incarceration rates as a natural byproduct.
