In the fight against climate change, Americans have been searching for alternatives to fossil fuels—developing solar, wind, and hydropower plants. Yet over the last decade, nuclear energy has experienced a renaissance, driven by its potential to deliver cheap, clean, and powerful energy. At the forefront of this revival is Jay Jiang Yu, CEO of NANO Nuclear, who is spearheading the development of compact, safe, and energy-efficient nuclear microreactors. But
Jay’s story does not begin in the towering offices of Wall Street—it begins in the heart of Harlem.
Growing Up in Harlem
Jay has always seen himself as an underdog, a mentality he credits for much of his success. While earning his psychology degree at the City College of New York, he also worked full-time in Columbia University’s finance department. His days ran from nine to five at Columbia, followed by classes from six to nine at City College. That grueling schedule taught Jay the value of time and the importance of creating tangible value in any role.
This focus on value helped him advance quickly at Columbia. Starting as a summer financial intern, he became indispensable by mastering the university’s complex financial systems. After graduating, he joined Columbia’s business management department, where he rotated across
finance, accounting, and HR. At just 21 years old, he was even appointed temporary head of the History Department during a restructuring. Jay became one of Columbia’s trusted “money guys,”
gaining hands-on experience in the mechanics of running a successful institution—experience that would later serve him as a CEO.
Reinventing Himself After Wall Street
From the start, Jay’s underdog spirit guided the Nano Nuclear’s approach. As the son of an immigrant who grew up in poverty, he felt he had to prove himself again and again. That drive pushed him to recruit world-class talent—including top scientists, engineers, and even former U.S. Secretaries of Energy and Four-Star Generals. “We want to go toe to toe with anyone,” Jay says, crediting his team’s relentless dedication.
NANO Nuclear’s work is reshaping the energy landscape. Traditional nuclear reactors rely on liquid cooling, which carries significant safety risks. By contrast, NANO Nuclear’s microreactors are self-contained, able to dissipate heat naturally and drastically reduce the risk of radioactive release. Compact yet powerful, these reactors can generate nearly 20 megawatts of clean energy—enough to power entire communities. In partnership with the University of Illinois, NANO Nuclear is preparing to submit its first construction application, paving the way for safe, scalable nuclear power across the United States.
Giving Back to the Community
Jay’s success hasn’t pulled him away from his roots. “It’s ingrained in my DNA to give back,” he says. “My mother was a seamstress, I was a sweatshop baby. I went through struggles, and I always felt lucky to gain access to opportunities—so I want to pay it forward.”
Growing up, Jay benefited from nonprofit basketball programs that gave inner-city kids like him structure and community. Inspired by those experiences, he donates to his old high school, funds supplies, and often gives talks to college students about entrepreneurship. He also founded
Lunar NYC, his own nonprofit supporting sports and education. Today, Lunar NYC serves over 100 kids, covering gym fees, uniforms, and tournaments—giving the next generation the same opportunities Jay once had.
Harlem’s Nuclear Pioneer
From Harlem’s streets to Wall Street to leading one of the most innovative energy companies in the U.S., Jay Jiang Yu embodies the spirit of the underdog. His journey—from City College student to Columbia “money guy,” from Wall Street banker to nuclear entrepreneur—reflects
resilience, vision, and determination. Today, he is not only reshaping the future of clean energy but also giving back to the community that shaped him.
Simply put, Jay Yu is Harlem’s own nuclear pioneer: revolutionizing an industry, investing in the next generation, and proving that underdogs can change the world.
