Saeju Jeong is the co-founder and Executive Chairman of Noom, a leading digital health and wellness company headquartered in New York City. Since its inception in 2008, Noom has been on a mission to empower people globally to lead healthier lives through behavioral change. Over his 17-year tenure as CEO, Jeong masterfully spearheaded the company's dramatic growth, securing $657 million from premier investors like Sequoia Capital and Silver Lake, which propelled Noom to unicorn status and ensured its sustainable profitability. His strategic vision has not only expanded the company’s global footprint but also positively impacted millions of lives and nurtured a vibrant corporate culture that champions innovation and collective success.

In July 2023, Jeong took on the role of Executive Chairman, marking a significant transition in his leadership journey. In this role, he continues to shape Noom’s strategic direction, focusing on expanding its influence in global health initiatives. Jeong leads Noom's engagements with the World Economic Forum and plays a critical role on the Steering Committee for the Forum’s Healthy Workforces initiative. His leadership is further recognized through his selection as a member of the prestigious 2024 Henry Crown Fellowship class at The Aspen Institute, reflecting his ongoing commitment to impactful leadership.

Jeong's contributions to business and health have been recognized globally. He has received multiple prestigious awards including EY’s Entrepreneur of the Year National Award in 2020, Harvard Business School’s Entrepreneurial Company of the Year in 2022, and Goldman Sachs' Builders and Innovators Award in 2022.

His active participation in the venture capital community involves investments alongside significant firms like Sequoia Capital, and he has significantly contributed to fostering entrepreneurship as the co-founder and co-chair of United Korean Founders, the largest network of Korean founders in the United States.

Jeong’s entrepreneurial spirit was evident early in his career when he founded South Korea’s first-ever heavy metal e-commerce business. This venture was just the beginning of his journey. The passing of his father, a respected physician, profoundly influenced his career trajectory, steering him towards a focus on preventive healthcare. This personal experience deeply inspired him and led to the founding of Noom, a platform dedicated to transforming the healthcare landscape from sick care to preventive care.

Today, Noom is recognized globally as a comprehensive destination for holistic health solutions. The platform offers targeted programs for weight management, obesity care, diabetes control, and stress management. Additionally, Noom has achieved success in the publishing arena with bestsellers like "The Noom Mindset" and "The Noom Kitchen," which have been widely acclaimed. Jeong's thought leadership and insights have been featured in top-tier media outlets, including “How I Built This,” “Masters of Scale,” an extensive brand interview in Inc., and a cover story in Forbes Korea in February 2025.
