When I talk to clients about investment diversification, I focus on strategic diversification within asset classes rather than broad, over-diversified portfolios. A lot of people think diversification just means spreading investments across as many different assets as possible, but that can actually dilute returns and make it harder to generate meaningful growth. Instead, I emphasize investing in a mix of asset classes (stocks, real estate, private equity, etc.) while keeping a focused, high-conviction approach within each one. With equities, I don't suggest buying every stock in an index. It's my opinion to focus on a concentrated portfolio of high-quality companies with strong fundamentals. In real estate, it's not about owning a little bit of everything, but rather selecting properties or markets with the best risk-reward balance. This allows for risk mitigation while still optimizing for strong returns. My advice is to diversify across asset classes, but be intentional and focused within them. That's how you create a portfolio that's both resilient and built for growth.
From my banking days at Sparda to now leading spectup, I've seen how crucial smart diversification is - but it looks different for startups than it does for traditional investors. During my time at Deloitte's Innovation & Ventures team, I noticed that many founders struggled with balancing resource allocation, often putting all their eggs in one basket. At spectup, we now advise startups to think about diversification not just in terms of investments, but in terms of revenue streams, market segments, and even technological approaches. I saw this work particularly well during my time at BMW Startup Garage, where successful startups often had multiple applications for their core technology. We encourage founders to build a foundation that can support various growth directions while maintaining enough focus to execute effectively. This approach helps protect against the common pitfall of running out of cash - which affects 38% of failed startups - by creating multiple paths to revenue. It's about finding the right balance between focused execution and strategic flexibility, something I learned firsthand while working on international expansion at Deutsche Bahn.
