Overview
Julie Capiau joined 100IN as a Partner alongside Jorn Vanysacker and Gilles Mattelin, who founded the fund following their exit from legal AI company Henchman in 2024. The 100IN model is structured around EUR 100K checks to 100 Belgian startups, deployed from a EUR 12M vehicle.
Julie brings a different background to the trio: where Jorn and Gilles came from a SaaS and legal tech operator path, Julie's prior experience spans consumer-facing brands including TheMerode and Maison Dandoy, a heritage Belgian biscuit house. This mix gives 100IN coverage across both tech-native and consumer brand ventures.
She holds a Master in Business Engineering with a specialization in Entrepreneurship from Solvay Business School (2010-2012).
Julie is also connected to the broader Belgian founder community through Syndicate One, the angel investment co-operative that brought together more than 120 founders, operators, and investors. Her participation in the EUR 22M oversubscribed first close of a Syndicate One vehicle underscores her embeddedness in the Belgian early-stage community.
Julie's profile is distinct from the typical Flemish tech-operator-turned-investor. Her Brussels base, Solvay pedigree, and consumer brand background broaden 100IN's deal flow beyond the Ghent SaaS cluster. She represents the growing participation of Brussels-based professionals in the Belgian startup investment ecosystem.

- If your work drains you, that's not normal. Go change it! I thought summer was going to be dead in VC. Turned out different. Nevertheless, I had the best summer ever. A job takes your energy. But when you start doing what you love and you are surrounded by the BEST people, it gives you energy. So grateful for this dream-team. 🍉❤️ Jorn Vanysacker Gilles Mattelin Stef-Kamil Fissette 100IN

- BEST OPPORTUNITY EVER!
- One year ago, WAT(beta) started. And a few months later, I made the biggest jump of my career. No tech background. No VC experience. Just a gut feeling and a lot of people looking at me like: "really?" I told Charlotte and Thibaud what we were doing: launching a fund, from scratch, and with me coming from a totally different world. They didn't ask me "Are you sure? Do you have the right background?". No. Just enthusiasm that made me believe I could do this. It was a small gesture, but had real impact for me. WAT(beta) turns one
