David Brillembourg Jr. dropped out of NYU at 18 to become employee number 5 at Galaxy Digital, where he helped build Galaxy Interactive's $325M gaming fund and deployed over $100M into gaming startups before launching his own fund at 21. As the sole partner at Dune Ventures, he focuses exclusively on interactive content and gaming companies, positioning himself as a low-ego consigliere who commits to decade-long relationships with founders and works particularly well with young, ambitious entrepreneurs.

• A distinct preference for unproven or unconventional founders over those with perfect credentials. He frequently highlights entrepreneurs who emerge from the fringes, such as college students who felt they did not belong on campus or self-taught builders who started extremely young, viewing these illegible backgrounds as a signal of high potential.
• Values courage and obsession as the primary differentiators between good and great founders. He looks for individuals treating their company as their life's work rather than those looking for a quick exit strategy, even suggesting that true courage sometimes means choosing not to start a company if the conviction is not absolute.
• Respects deep preparation and comprehensive answers during the diligence process. He pointed to an interaction regarding Genentech to illustrate that the most impressive founders are those who have thought through every aspect of their business and have a ready answer for every difficult question an investor might ask.
• Focuses on high conviction and concentrated bets on non-obvious people. He admires investment strategies that involve taking significant positions in special founders before they are recognized by the wider market, explicitly criticizing the tendency of the industry to seek safety in consensus.
