What does it really take to back the right idea at the right time? And why might humility, not hype, be the most underrated trait in great investors?

In this episode of Europe Builds, we sit down with Nick Kalliagopoulos, Partner at Big Pi Ventures—one of Greece’s most prominent VC funds. With a decade of experience spanning Prime Ventures in Amsterdam and the Randstad Innovation Fund, Nick brings a rare blend of insight from both deep tech and the future-of-work sectors. We discuss how to evaluate truly transformational technology, what traits set apart the founders worth backing, and why ego can be a liability on both sides of the investment table. Nick also shares lessons in timing, discipline, and the quiet power of long-term conviction.

For anyone building or betting on the next frontier, this episode is full of insight.
