Different perspectives united by shared values
Our Story
Founded in 2014, JBG Capital is a Wealth Management and Investment Solutions firm based in Geneva, dedicated to preserving and growing family legacies across generations.
In an industry often driven by short‑term narratives and increasing complexity, JBG Capital takes a different view. We do not see capital purely as a financial asset, but as a long-term responsibility, a partnership, and a lasting legacy. Every relationship we build reflects that understanding.
For us, Wealth Management begins with trust, is strengthened through personalized guidance and is shaped by a deep understanding of what matters most to our clients.
The foundation of our enduring Investment Solutions is built on a rigorous framework, perseverance and conviction.
We use disciplined processes and evidence‑based analysis to bring clarity to complexity. With conviction and independent assessment, our strategies are designed to perform across changing market cycles.
Our commitment to upholding the highest Swiss financial regulatory standards is demonstrated by our FINMA authorization under AOOS supervision.
Founders
JBG Capital was founded in Geneva by Jean‑Benoît and Marylène Guex. Together, they bring decades of complementary experiences. United by the ambition to offer a personal and multi‑generational approach to Wealth Management, their shared vision is grounded in integrity and a genuine commitment to clients.
Jean‑Benoît held senior leadership roles within the international private banking industry, shaping teams across Geneva, Europe, and the Middle East, developing deep expertise in investment, governance, and strategic advisory.
Marylène, with a background as an entrepreneur and in human resources management, contributed a thoughtful, people‑focused perspective that helped shape the firm’s culture, values, and collaborative spirit. Her approach has always been grounded in discretion and care, alongside a deep sense of responsibility toward clients.
Since its founding in 2014, JBG Capital embraced an entrepreneurial mindset, curious, forward‑looking, and committed to creating enduring value. Today, the founders’ principles continue to guide the firm: being a trusted partner aligned with clients` long-term interests, operating in a transparent and efficient framework.

Whether supporting family wealth, entrepreneurial success, or institutional capital, we seek to align investment strategies with long-term objectives, governance considerations, and legacy planning.
