He also runs the early-stage fund Festina with Jorn van Dijk. He is based in Amsterdam.
Crunchbase, PitchBook and Tracxn list him as an individual angel investor. Their deal counts differ (roughly 9 to 21 investments), so treat any single figure as approximate. His recorded deals include a CodeSandbox seed round (May 2019), a Revue angel round, a Pitch Series A and a Float seed round (May 2024, led by Point Nine). Crunchbase lists Revue, CodeSandbox and VoidZero among his exits.

On the Lounge deals desk, he is listed in Bounti's Seed round of $4.6M (EUR 4.0M), dated March 2026. PitchBook records the same deal on 19 March 2026 and describes Bounti as a Berlin company. Crunchbase lists Common Magic and 7 other investors in the round.
His other recent deals are mostly in software and developer tools. Public sources do not describe his AI thesis, so none is stated here.
EasyVC lists his stages as pre-seed and seed. His recorded deals also include Series A rounds (Pitch, VoidZero), so he has not limited himself to the earliest stages. Tracxn shows his deals mainly in enterprise applications and enterprise infrastructure, mostly in the United States and the Netherlands. Festina is described as an early-stage fund for software companies with strong user experience design.
He has not published a check size or a statement of what he looks for. Third-party databases give figures, but they are not first-party and are not repeated here.
