Serraes is named as one of the angel investors in Exhibitly's €1.4M pre-seed round. Tech.eu and EU-Startups reported the round on 19 May 2026, while the Lounge deals desk records it as 2026-07. New School VC led it, with 100IN, Allusion Ventures and several angels taking part. Exhibitly is a Ghent company founded in 2025 that builds AI personalisation for B2B event websites. It plans to grow its team from three to seven people.
In a LinkedIn post about the deal he said the founders, Hendrik Franck and Brent Coppens, fit the usual investor checklist of traction, team, market size and timing. He said what won him over was that they were willing to shut down their own product twice.
