Maarten Slendebroek
The Navigator
Judgement in the fog, money, risk and the call others cannot make.
Maarten Slendebroek demonstrates the Navigator archetype throughout this interview, charting deliberate courses through shifting landscapes across multiple decades and institutions. He describes moving from legal work on the Amsterdam Stock Exchange to equity analysis, then through Merrill Lynch, BlackRock, Jupiter, and finally Robeco's supervisory board with a clear-eyed pragmatism about where value and opportunity lie. Slendebroek reads structural change early, whether mobilizing BlackRock's Aladdin platform during the financial crisis or recognizing Robeco's ESG positioning as a durable competitive moat rather than a trend. His investment philosophy reflects the same orientation: he backs management teams, seeks margin of safety in unloved markets, and resists purely algorithmic certainty. He guides rather than disrupts, synthesizing quantitative and fundamental lenses while keeping long-term institutional orientation firmly in view.
“What you need in asset management is scale in product. You don't necessarily need to be BlackRock to be successful. There are firms with asset levels of less than 10 billion that can motor on forever.”
“I rang the doorbell of the UK Treasury and effectively said, can we help with anything? And it was absolute chaos there because they were struggling with banks, RBS, and others.”
“If you start that game today, you're never going to catch up. So I believe that Robeco indeed is in a strong position to continue to grow its footprint, particularly in that space.”
