100IN is a Belgian investment group led by Jorn Vanysacker and Gilles Mattelin, both of whom exited Henchman, the Ghent-based legal AI company. The group invests the proceeds from that exit into new Belgian tech ventures.

In the news
- Not long ago, Conveo was a handful of people in Antwerp. Today, we have offices across Europe and the U.S., and we work with more than 400 enterprises, including 50+ of the Fortune 500. This week at Tectonic in Ghent, I swapped founder stories with Manu Vanderveeren from Spott. Thanks to Jorn Vanysacker from 100IN for moderating. Here are three things I’d tell any founder starting out. 👉 Early on, hire people who can grow into the job, because nobody knows yet what the job will look like next year. Later, add people who’ve done it
- Pitched Kasqade at the Tectonic pitching competition finals yesterday! Unfortunately, top 10 was all we managed to achieve, but still proud to have represented our team in front of judges from 100IN, Entourage Ventures, Baseline, and ScaleFund. Congrats to Paldo for taking the bag 💰, and thanks to the entire Tectonic crew for an exciting and energising day right in our home base at Wintercircus Ghent. Till next year!
- I don’t need to tell you something special is happening in Belgian tech. New blood is coming in from great companies and universities, just like Boris, Michiel, and Stef-Kamil(and team), who are organising Tectonic, one of the biggest tech conferences in Belgium. Startups and VCs from across Europe, in one Wintercircus. Built on ambition, hustle and a lot of late nights. This is what a compounding ecosystem looks like. Throw in a TechWolf exit from last week and it feels like we’re only getting started. Exits return more than
- Le 1er juillet 2025, Florent Quinti, Partner chez Hexa, publiait un simple post LinkedIn autour d’une idée : ResearchX. Un peu plus d’un an plus tard, cette idée est devenue une vraie boite. Lydia Bellahouel et Camille Epitalon ont lancé Verso (HX26) avec une conviction forte : les grandes entreprises auront toujours besoin de rester au plus près de leurs clients pour imaginer et améliorer leurs produits. Mais l’IA change complètement la manière de le faire. Verso permet d’interroger de vrais consommateurs, d’analyser des milliers
- Verso runs AI-led consumer interviews at 10x the speed and a quarter of the cost. The first 30 customers include Ferrero, Orange and Michelin. $6M raised, led by Angular Ventures, with Kima Ventures, Olympe Capital, Sharpstone Capital, some great angels, and we couldn't resist. Lydia, Camille — we didn't need a focus group for this one 😘
- For any company, unpaid invoices are silent killers. Chasing them manually is still how most of Europe's mid-market operates. Enter Cleavr. 80% less manual work. 37% fewer payment delays. 100+ customers across Europe in just a few months. €8M seed, led by Varsity, with Kima Ventures, Better Angle, Portfolio Ventures, Clover and us. Baptiste, Antoine, Arthur, we paid. On time. You're welcome. 🖤
- Our portfolio company NOX Energy raised €3M to build the infrastructure behind flexibility. One software layer connecting heat pumps, solar panels, batteries and EVs to energy markets, embedded directly into OEMs and energy retailers across Europe. Over the next years, millions of flexible devices will come onto the grid. They need to be connected. They need to be controlled. And their flexibility needs to become valuable. NOX Energy wants to be the infrastructure behind every kWh of it. Congratulations to Axelle Moortgat & Louis
- May 29th, 2024. A hot day, a slightly cramped office, and our first meeting with the Noxians. The energy in the room (pun very much intended ⚡) was incredible. Afterwards, we loved the vision and the ambition. But we also asked ourselves an honest question: could a team this young (22 and 23 at the time) really make a dent in a market this complex?
