Investment leader Samer Choucair said the stories of four billionaires born in Lebanon — Sami Mnaimneh, Tony Tamer, Noubar Afeyan, and Karim Atiyeh — offer an important example of how human capital can move from individual talent to institutions capable of creating and scaling value globally.
Choucair explained that the latest Forbes estimates published in August 2026 put the fortunes of Mnaimneh and Tamer at approximately $7.8 billion each, while Afeyan and Atiyeh were each estimated at around $1.9 billion. Combined, their fortunes amounted to approximately $19.4 billion based on those snapshots in time, with the understanding that wealth estimates fluctuate with market movements and private-company valuations.
Choucair noted that the more important story is not the size of the fortunes, but the different models that created them. Mnaimneh and Tamer founded H.I.G. Capital in 1993, which developed into a global alternative-investment platform managing approximately $70 billion, with a historical focus on middle-market companies alongside credit and other strategies. This trajectory demonstrates the importance of transforming deal-making expertise into an investment institution capable of operating across multiple economic cycles.
In biotechnology, Noubar Afeyan represents a different model. He founded Flagship Pioneering and serves as chairman and co-founder of Moderna. Throughout his career, he has contributed to the creation of more than 70 companies in life sciences and healthcare.
Choucair said the value of this model lies in building a system capable of transforming scientific ideas into multiple companies and distributing risk across a portfolio of innovations rather than relying on a single project.
Karim Atiyeh, co-founder and chief technology officer of Ramp, represents a newer generation of financial technology. Ramp was founded in 2019 and, in June 2026, secured $750 million in funding at a $44 billion valuation in a round led by ICONIQ, GIC, and the Ontario Teachers’ Pension Plan.
Choucair emphasized that these four paths reveal a common principle in building substantial wealth: sustainable value does not come from owning a single asset, but from building a platform that can scale and be replicated. H.I.G. transformed investment expertise into an institution, Flagship transformed scientific research into a company-creation model, while Ramp is transforming corporate financial operations into an AI-powered digital platform.
Choucair added that the presence of 144 billionaires born outside the United States, with a combined fortune of $2.2 trillion according to Forbes, highlights the role played by deep markets, universities, venture capital, and financial markets in turning immigrant talent into companies, wealth, and employment opportunities.
“The lesson for sovereign wealth funds and Gulf investors goes beyond celebrating success stories,” Choucair said. “It is about investing in platforms capable of repeatedly creating value.”
He added that the next phase of capital allocation will reward institutions that combine capital with operational expertise, technology, and governance, because growth alone is no longer sufficient. More important is a company’s ability to convert new capital into sustainable returns.
Samer Choucair concluded that the stories of these four billionaires offer a clear lesson: capital follows talent, but it settles where institutions exist that can transform talent into a continuous system of innovation, growth, and value creation.
