At just 23, Zier Hassan — widely known as “Zoio” — has achieved what many seasoned entrepreneurs and fund managers spend decades pursuing. His journey from building a successful streetwear brand as a teenager to steering hundreds of millions in guided portfolios illustrates not only ambition, but an unrelenting pursuit of mastery.
Hassan’s entrepreneurial path began at 18, when he launched his first streetwear label named ”Glücksmann“ and quickly scaled it to seven-figure revenues. Yet for him, success in retail was never the destination. “A few million a year isn’t enough if you want to play in the same league as the truly big players,” he recalls.
Instead of following the typical distractions of youth, Hassan immersed himself in the mechanics of the capital markets. He dissected balance sheets, market cycles, and trading psychology — not in theory, but in real time, applying each lesson with discipline. The results spoke loudly: a 123% return in 2023, followed by an astonishing 228% in 2024, achieved exclusively through single-stock selection and timing, without leverage.
As word of his performance spread, friends and family sought his guidance. That circle quickly expanded. Today, Hassan advises an exclusive investor base with an accompanying portfolio volume exceeding €280 million.
What sets him apart is his model. Hassan never takes custody of client funds. Investors maintain full control of their assets while he provides strategic guidance and conviction-based recommendations.
His compensation? A simple, transparent formula: a 30% performance fee on realized profits. “Our incentives are perfectly aligned. I win only when my clients win,” he explains.
This alignment — paired with remarkable returns — has positioned Hassan as one of Europe’s most intriguing young figures in finance. Yet he views his current success as just the beginning. His ambition is to scale the accompanying portfolio volume into the ten-figure range, challenging an industry long dominated by older institutions.
“I don’t play to remain a millionaire,” Hassan says with quiet certainty. “I play to rewrite the rules.”
