01 / Profile

An independent operator.

Guillaume Kevin Jenner is a self-made entrepreneur and private investor with active operations across France, Hong Kong, Singapore and the United Arab Emirates.

Over years of independent activity, he has founded and scaled multiple companies in technology, B2B services and the blockchain sector, while developing an international portfolio of venture investments and real estate holdings.

His approach is grounded in disciplined analysis, a long-term strategic perspective, and an uncompromising commitment to ethical conduct and corporate governance.

02 / Background

Built without a blueprint.

Guillaume's career began without the benefit of formal higher education. He built his foundation through self-instruction, applied practice, and disciplined capital management.

In an earlier chapter of his career, professional poker provided both a rigorous training in probabilistic thinking and the initial capital that funded his first business and investment activities. He withdrew from the professional circuit several years ago to focus exclusively on entrepreneurship and investment; the analytical discipline acquired during that period continues to inform his work today.

What followed was a decade of operating: building, scaling, divesting and reinvesting. Each chapter has reinforced a single conviction — that durable value is created at the intersection of patience, conviction and rigorous execution.

Never start a fight, but always finish it.

B. Investor

Venture capital

Direct seed and Series A investments in technology ventures, alongside selective venture-capital exposure.
