Hoang Kieu Net Worth, Relationships, Age/Birthdate & Birthday

Hoang Kieu is a Vietnamese-born American entrepreneur, best known for building a global blood-plasma business and founding a Napa Valley winery — once ranked among the world’s richest.

Introduction

Hoang Kieu (birthdate: 1944) rose from humble beginnings in central Vietnam to become one of the most notable Vietnamese-American businessmen. Born in Bich Khe village, Quảng Trị Province, his journey took him from rural hardship to co-founding and building Shanghai RAAS Blood Products, and later launching a Napa Valley wine venture under Kieu Hoang Winery. At his peak, his estimated net worth reached billions, though subsequent challenges dramatically altered that fortune. Publicly linked to a high-profile relationship, his personal life has drawn as much interest as his business success.

Quick Facts

From War-Torn Vietnam to American Opportunity

Hoang Kieu was born in 1944 in Bich Khe village, Trieu Phong district, Quảng Trị Province.  His early childhood was marked by hardship — he grew up barefoot, helping his family with simple but demanding tasks just to survive. 

When he was about five, he moved to Saigon to live with his uncle, a known artist, who ensured he had access to education.  He began studying science at university, but the upheaval of war altered his path. As the conflict escalated and Vietnam underwent major transformations, Hoang Kieu made a life-changing decision: in 1975, just as the war ended, he immigrated to the United States. 

In America, his early years were difficult. He started with modest jobs, including working at a lab for minimal pay.  Yet, Hoang quickly demonstrated determination and resilience. Within a short time at Abbott Laboratories, he rose from entry-level to become director in charge of plasma sample testing. 

Deciding to leverage his knowledge, Hoang founded his own company in 1985 focused on blood-plasma. Over the next several years, he expanded operations, and in 1992 established Shanghai RAAS Blood Products — entering the Chinese market at a time few Western entrepreneurs dared to venture there. 

Defining moments in Hoang Kieu’s journey include:

• Immigrating to the United States in 1975 with almost nothing, yet securing a job at Abbott Laboratories. 

• Founding his first blood-plasma company in the U.S. in 1985, establishing 11 plasma centers nationwide. 

• Launching Shanghai RAAS Blood Products in 1992, successfully penetrating the Chinese blood-plasma market.

• Expanding beyond healthcare to wine — purchasing a Napa Valley winery and inaugurating it with high-profile events. 

Through grit, ambition, and strategic vision, Hoang transformed from a refugee to a global businessman.

The Core Pillars of Hoang Kieu’s Wealth

The core pillars of Hoang Kieu’s wealth include:

• Ownership in Shanghai RAAS Blood Products — The lifeblood of his fortune. When the company went public, its stocks soared, and Hoang’s stake made him a billionaire almost overnight. 

• Founding Rare Antibody Antigen Supply (RAAS) in the U.S. — His first venture into plasma-based healthcare services, providing the foundation for later expansions. 

• Wine and Lifestyle Business with Kieu Hoang Winery — Purchased a vineyard in Napa Valley and marketed wine under his brand, blending his interest in health, lifestyle, and business. 

• Diversified Assets and Investments — Over the years he reportedly held real estate, ranches, and other asset types beyond plasma and wine. 

These multiple streams — healthcare, wine, real estate — formed a diversified wealth base for Hoang.

Relationships & Personal Life

Although much of Hoang Kieu’s life has been private, some aspects of his relationships and personal background are public.

• He has children — several sources mention that he has five children. 

• In the mid-2010s, he gained public attention for his romantic link with Ngoc Trinh, a high-profile Vietnamese model and celebrity. 

• Their relationship stirred public debate because of the significant age difference between them. 

• Some reports note that despite his vast wealth at one time, questions about divorce, children’s views, and inheritance began circulating amid his financial downturn. 

Key insights into Hoang Kieu’s relationships and personal life:

• He had a large family, with five children prior to his public romantic link.

• His connection with Ngoc Trinh brought renewed public scrutiny to his personal life.

• The high-profile relationship also stirred speculation about inheritance and wealth transfer.

• Despite personal controversies, Hoang maintained a reputation for privacy regarding his earlier family life.

A Life of Luxury, Wine, and Giving Back

Beyond career success, Hoang Kieu leads a lifestyle that reflects both passion and purpose, including:

• Investing in a Napa Valley winery — blending his entrepreneurial spirit with a taste for lifestyle and culture.

• Owning a ranch outside Los Angeles: according to sources, a “$33 million ranch called Hummingbird Nest,” used for events and private gatherings. 

• Engaging in philanthropy: He reportedly donated millions to disaster relief efforts in the U.S. and supported social projects in Vietnam.

• Maintaining ties to his homeland — periodically returning to Vietnam, supporting community and development projects, and remembering his humble roots. 

Net Worth Breakdown & Analysis

Hoang Kieu’s net worth has fluctuated significantly over the years. Here's a breakdown of how his wealth was structured during its peak, and how business variables affected it:

What happened to cause decline:

• In 2017, a sharp fall in shares of Shanghai RAAS reportedly caused a drop of about 70% in his net worth. 

• In interviews, Hoang admitted to large debts — reportedly around US$3 billion — during the downturn. 

• As a result, he dropped off the billionaire lists, and media narratives shifted from meteoric rise to financial struggle. 

This volatility underscores the risks inherent in stock-heavy fortunes and single-industry concentration — even for someone as driven and experienced as Hoang Kieu.

Public Image, Legacy & Influence

Hoang Kieu’s public image is a blend of immigrant-success legend, controversial figure, and philanthropic businessman.

• Many view him as a quintessential “American dream” success story — a refugee who built a multinational enterprise through grit and vision. His rise from testing plasma for a few dollars an hour to owning one of China’s largest plasma-based companies resonates widely. 

• His foray into wine and luxury lifestyle with Kieu Hoang Winery added another layer — showing adaptability beyond core industry, bridging East and West, business and culture. 

• On the flip side, the dramatic drop in fortune and reports of debts have raised serious questions about over-leverage, risk management, and sustainability. His own comments reflect awareness: “You can be a billionaire today, and tomorrow you’re not a billionaire,” he once said. 

• In Vietnam, his legacy includes philanthropic gestures: charitable donations, efforts to build homes for the poor, and maintaining a degree of connection to his homeland in spite of global success. 

Conclusion

Hoang Kieu’s story — from a rural village in Quảng Trị to becoming a globally recognized entrepreneur — is a powerful narrative of ambition, risk-taking, resilience, and the complex reality of wealth. His estimated net worth once soared to as much as US$3.8 billion, his ventures spanned continents, and his personal life captured headlines. His birthdate in 1944 marks the beginning of an extraordinary journey.

But wealth, as Hoang has acknowledged, is fragile — subject to market swings, debt, and unforeseen downturns. His story reminds aspiring entrepreneurs that success often comes with volatility. Through it all, his legacy remains: a pioneering immigrant entrepreneur who built an empire, ventured boldly into new industries, and never forgot his roots.
