Martin Giese has spent 25 years at the centre of Munich's deep tech ecosystem — and he thinks most European founders have a blind spot that no incubator programme will fix: they can't sell.

As Managing Director of XPRENEURS (now UTUM Accelerator) and guest lecturer at Stanford GSB, Martin has seen founders across three continents make the same mistake.

In this episode, we dig into what Stanford founders understand about customers that TUM founders typically don't, why the Europe-US gap is more cultural than financial, and what it actually takes to build a B2B company that scales past the first few customers.

Join me as I speak with Martin Giese — investor, incubator director, and one of Europe's most clear-eyed voices on what it really takes to sell deep tech.
