Jérôme is a co-founder and Managing Partner at Expon Capital.
He has been active both as a tech investor and as an entrepreneur across many cycles and multiple trends.
Jérôme's journey in tech investing began in 1994 with M-Systems, a $25M company with a bold vision to revolutionize data storage. That investment delivered a 60x return and a $1.6B exit, but its true legacy lives in every smartphone today— without flash memory technology no mobile computing would be possible. That experience taught him the value of spotting transformational technology before the world catches on—a lesson that continues to guide him. Since then, he has been involved in the foundation of several companies, some of which have gone on to achieve great outcomes.
At Expon Capital, this philosophy has led him and his team to valuable failures and remarkable successes—from Glovo's €2B exit and Spire Global's $1.2B IPO to helping pre-seed companies like Passbolt, Next Gate Tech, and Salonkee grow into local champions. He loves to partner deeply with founders, helping them scale from €1M to €100M in revenues by cultivating a winning mindset and leveraging the firm's global network.
Since childhood, Jerome has been fascinated by new technologies and scientific discoveries across physics and biology. He has always been curious about understanding their impact, spotting future trends and discovering how to turn them into value. He is fascinated by developments in the fields of AI as well as by SpaceTech, Omics, Synthetic biology, Thorium-based energy generation.
Active in multiple non-profit organisations supporting education and entrepreneurship (Junior Achievement Luxembourg, Initiator of the Luxembourg Chapter of Stanford University's How to Start a Startup Class), Luxembourg's internet connectivity (LUCIX.lu) and Luxembourg's Venture Capital & Private Equity Association (LPEA.lu), of which he is the former Chairman and currently an Executive Committee member.
Jérôme graduated Cum Laude from the University of Louvain, where he obtained a Master of Law. He received his MBA from the Rotterdam School of Management, Erasmus University. He is fluent in French and English and has a passive knowledge of Luxembourgish and Dutch.
