Steward of Entrepreneurial Wisdom
Delarey Brugman
Steward of Entrepreneurial Wisdom
Delarey Brugman is widely regarded as the curious and instinctively insightful entrepreneur whose career is recognized for its depth, range, and human-centered impact. From his formative years at Grey College, travelling over 25 countries and studies, to leadership across multiple industries, he has consistently identified potential and created conditions for it to flourish. His entrepreneurial record spans private equity, venture capital, sports management, distribution, hospitality, property development, financial services, direct sales, agriculture, tourism, value-chain optimisation, brand creation, international hotel boards, and a technology arbitrage fund. Many ventures expanded internationally, some reaching public listings, highlighting his capacity to build resilient, operationally fit organizations and designed complex legal frameworks. As a pioneer in South African sports management, Delarey became known for elevating world-class athletes and pioneering the value adding - creating brands of the superstars. His personal brand - loyalty, strategic mastery, and courage - inspired clients to transform performance into legacy. A lifelong student of human performance, he has competed internationally and provincially across seven sports and read over 300 books on critical thinking, philosophy, politics, psychology, spirituality, economics, leadership, fatherhood, excellence, deal-making, and negotiation. His commitment to action is reflected in the “Give Me a Chance” Children’s Foundation, recognized for developing courageous youth from overlooked communities - including an orphan he mentored who became an auditor, sparking hope in forgotten places. After exiting his international sports agency, Delarey chose a path aligned with purpose: devoted husband, present father, and community contributor. He created a wine for his wife, daughters, and great-grandfather General De la Rey, honouring those who matter to him. This journey evolved into curating “The Great Minds,” a collective of brilliance dedicated to solving complex problems and accelerating the next generation. Delarey has collaborated with global high-net-worth individuals, majority shareholders of banks, and senior leaders of listed companies, gaining insight into decision-making at the highest levels. His advisory network includes world record holders, politicians, ministers, Hollywood award-winners, professional athletes, HNW families, board members, professors, and spiritual leaders - including those who have advised a former American president. Their wisdom and integrity continue to guide his work and relationships. At outsourcedactuaries.ai, Delarey is valued for his ability to recognize talent, align strengths, and foster exceptional teams. He also draws from his global network, insights, and experience to deliver unique entrepreneurial optimisation of “The Great Minds” - contributing towards bespoke solutions, strategic advice, and innovative ideas that augments client value. He is a former Christian Church Council member, completed an 11-day Vision Quest, and continues disciplined Spiritual Direction. He measures success by lives improved and capabilities expanded, instilling belief and courage so you can become the best version of yourself and provide you with the tools to make it happen.
