Michael Gastauer: The Youngest Self-Made Billionaire Redefining Germany’s Wealth Landscape

Germany’s wealthiest individuals are largely known, but Michael Gastauer shakes up the list. While entering the billionaire ranks is not unusual, Gastauer stands out as the youngest self-made billionaire in the country, with the potential to eclipse them all.

Unlike many of his counterparts, Gastauer didn’t inherit his fortune. He built it himself, starting as a financial executive before venturing into entrepreneurship. In 2015, he identified global challenges in digital banking and founded Black Banx, a digital banking platform aimed at dismantling the barriers of traditional finance and offering global accessibility.

What began as a disruptive fintech concept has evolved into a global digital banking powerhouse, now serving 61 million customers worldwide—an impressive leap from the 5 million it boasted six years ago. In just three years, by 2018, Black Banx had achieved a staggering valuation of $9.8 billion. Fast forward to 2024, and though the company’s private status prevents an official valuation, experts suggest it could be worth as much as major competitors like Revolut, which was valued at $45 billion in 2024.

However, Gastauer’s success is not just about user numbers or company valuation. Black Banx is expected to generate $2.9 billion in profits in 2024, with the vast majority of that profit going to Gastauer and his family, who own 99.9% of the company. This puts him in league with some of Germany’s wealthiest individuals, such as Klaus-Michael Kuehne, who is set to receive $4.5 billion in dividends this year, and Reinhold Wuerth, whose group earned $1.5 billion in profits last year. Gastauer’s payout isn’t far behind, and considering his age and Black Banx’s private status, it’s clear he’s only just begun.

Valuing a privately held company like Black Banx is no easy task, especially without recent share sales. However, given its financial performance and growth trajectory, it’s likely Black Banx could be valued similarly to public companies in its industry. A company generating $2.9 billion in annual profits could easily be worth 15 to 20 times that amount if publicly traded.

Should Gastauer decide to take Black Banx public, the valuation could skyrocket, potentially making him Germany’s richest person. Holding nearly all of the company’s shares, Gastauer would see his fortune soar. Going public is often seen as a pivotal step for tech companies, with examples like Apple, Microsoft, and Amazon reaching new heights after opening to public investment. Their founders—Jobs, Gates, and Bezos—became household names, known not just for their wealth but for reshaping industries.

For Gastauer, an initial public offering (IPO) could offer similar opportunities, catapulting Black Banx and its founder to even greater global prominence. However, it would also mean ceding some control, a major consideration for a self-made entrepreneur. Currently, Gastauer has total control over Black Banx, something he would have to share with shareholders if the company went public. Market volatility, another factor public companies contend with, could also be avoided by staying private.

Gastauer may find maintaining control more valuable than the potential benefits of going public. His ability to build a multi-billion-dollar empire without external involvement has already proven immensely successful. Still, if he ever decides to take Black Banx public, it would not only cement his position as Germany’s wealthiest individual but also mark a shift in the country’s billionaire narrative. Unlike most of Germany’s richest, who inherited their wealth through family businesses, Gastauer represents a new generation—self-made, driven by technology and innovation.

This transformation isn’t limited to Germany. In the U.S., many of the wealthiest individuals, such as Elon Musk, Jeff Bezos, and Mark Zuckerberg, are also self-made entrepreneurs who reshaped their industries through innovation. Gastauer’s rise could signal a similar shift in Germany, where entrepreneurship and technological advancement might begin to eclipse old-money wealth.

Regardless of the path he chooses, Gastauer has already left an indelible mark on the financial world. Whether he keeps Black Banx private or opts to go public, his legacy is poised to influence the future of entrepreneurship in Germany and beyond.
