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 and his wife, Julie, together 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.
The foundation’s first focus area centers on narrowing 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.
