Why and how did you decide to go into the financial sector? Did you have other vocations?
I’ve always been drawn to fields that require both problem-solving and the ability to think analytically and creatively. Computer engineering runs in my blood—my father founded one of the earliest software companies in France, my uncle is a prominent figure in the tech industry, and even my brother, a renowned architect, specializes in parametric architecture, which heavily relies on algorithms. Naturally, I started my career exploring innovation in technology, working as a game designer for a football video game, developing websites in the sports industry, and collaborating with industrial clients on complex systems.
The problem-solving and innovation I explored in technology naturally led me to finance, where I found a similar need for creativity, data-driven thinking, and tackling complex challenges. Hedge funds and alternative investments fascinated me because they were dynamic, intellectually stimulating, and offered endless possibilities for innovation. Co-founding DBi has been the perfect way to channel this drive: we are pioneers in hedge fund replication, a space where we leverage systematic, data-driven approaches to disrupt traditional investing. Our mission is to democratize access to sophisticated strategies while setting new standards for transparency, efficiency, and cost-effectiveness.
What is your view of the current macroeconomic environment, and how might it affect markets? How do you manage the current uncertainty?
The current macroeconomic environment is characterized by high levels of uncertainty. Persistent inflation, rising interest rates, trade wars, and geopolitical tensions are creating challenges across asset classes. The recent election of Donald Trump adds further complexity. On one hand, his push for higher tariffs and a protectionist trade agenda could disrupt global supply chains and escalate tensions between major economies. On the other hand, his pro-business policies, such as tax cuts and deregulation, could spur domestic investment and corporate profitability, creating opportunities in certain sectors. Central banks are also walking a fine line between controlling inflation and avoiding recession, while markets are grappling with the end of an era of ultra-low interest rates and relatively free trade.
In this environment, markets are likely to remain volatile, and traditional diversification may not provide the same level of protection. At DBi, we manage uncertainty by focusing on systematic, factor-based strategies that seek to replicate hedge fund performance. By identifying and isolating key return drivers, we aim to deliver consistent performance, regardless of the broader market environment. This approach allows us to adapt dynamically to shifting macroeconomic trends, such as changes in trade or fiscal policy, while maintaining robust risk management.
How should investors orient their portfolios in this environment? What are the biggest risks facing investors?
Investors should prioritize diversification, but they must think beyond traditional stock-bond allocations. In today’s environment, incorporating uncorrelated strategies, such as hedge fund replication, is critical for navigating volatility and inflationary pressures. This approach helps to cushion portfolios from sharp drawdowns while still capturing upside opportunities.
One of the biggest risks facing investors right now is overconfidence in a single narrative, such as “inflation has peaked and will decline steadily” or “a soft landing is inevitable.” Markets are rarely so straightforward, and the interplay between inflation, interest rates, and economic growth remains highly uncertain. In uncertain times like these, hedge fund replication offers a flexible and resilient way for investors to diversify their portfolios and weather the challenges ahead.
What differentiates DBi’s Funds from others, and what advantages can they bring to an investor’s portfolio in the current scenario? How would you describe DBi’s investment philosophy?
DBi’s funds stand out because we bring the benefits of hedge fund investing—diversification, downside protection, and non-correlated returns—without the traditional drawbacks of high fees, lack of transparency, and illiquidity. Our proprietary process replicates the performance of leading hedge funds by targeting the same core factors and strategies they use but in a more cost-effective and transparent manner.
Our investment philosophy centers on democratizing access to sophisticated strategies. We believe that investors should be able to achieve hedge fund-like outcomes without paying the “hedge fund price tag.” In the current environment, where traditional asset classes face headwinds, DBi’s funds can play a pivotal role in providing stability and diversification in portfolios.
Can you give us an example of a position that you have held for a long time in your portfolios and why?
One of the key strengths of our approach is that we don’t focus on individual securities but rather on factor exposures that replicate hedge fund strategies. Our portfolios are constructed to go long or short across key financial indices in multiple asset classes, giving us the flexibility to adapt to changing market conditions. For example, in 2022, our largely unconstrained portfolio allowed us to short U.S. Treasuries and capitalize on the sharp rise in interest rates—a position that many traditional portfolios struggled to navigate effectively.
By structuring portfolios around these systematic exposures, we eliminate the risks and inefficiencies of stock-picking and instead focus on delivering the return profile that investors expect from leading hedge funds. This approach provides both adaptability and consistency, which are cornerstones of our investment philosophy.
What is hedge fund replication? Can you explain your investment process?
Hedge fund replication is a way to capture the performance of hedge funds without actually investing in them. Instead of owning the hedge funds themselves, we look at how they generate their returns and replicate those strategies using more straightforward, cost-effective, and liquid tools like ETFs or futures.
Here’s a simple analogy: imagine you want to replicate a chef’s signature dish. You don’t need the chef in your kitchen—you just need to figure out the key ingredients and how they’re put together. Hedge fund replication works in a similar way. At DBi, we study the performance of top hedge funds to uncover the “ingredients” driving their returns. These might include things like exposure to certain stock markets, trends in commodities, or changes in interest rates.
Once we’ve identified these ingredients, we use liquid and transparent financial instruments to recreate the same exposures. The result is a portfolio that behaves similarly to the hedge fund but with lower costs, greater transparency, and no lock-ups.
At DBi, we’ve developed a systematic process to do this. We focus on replicating hedge funds by targeting the key factors that explain their performance. By using this approach, we provide investors with hedge fund-like diversification and returns, but in a much simpler, more accessible, and cost-effective way.
What do you like to do in your free time?
As much of my work involves sitting alone in front of multiple screens, my favorite way to spend my free time is with my loved ones. I love playing games with my two kids—they keep me on my toes, and honestly, I’m still very much a kid at heart myself! I also enjoy working out with my dad, even though we probably drive our coach crazy by spending 90% of the session joking around. And, of course, I cherish nights spent partying and sharing laughs with my wife and closest friends. For me, it’s all about quality time, humor, and staying connected with the people who matter most.
