Overview
His pre-Shayp work included Stylicist, a smart wardrobe assistant that suggested outfit options from a user's clothing behaviour. Shayp began with Alexandre McCormack researching leak detection technology in 2016. McCormack, an architecture and civil engineering graduate of ULB who had been an energy manager for Brussels, was chief executive; de Hemptinne was chief operating officer and Wakrim chief technology officer.
Grégoire de Hemptinne is co-founder and chief executive of Shayp, a Brussels water technology company started in October 2017 with Alexandre McCormack and Zineddine Wakrim. McCormack was chief executive at the company's 2020 funding round, and de Hemptinne held the chief operating officer role, which he still carried in January 2024. He holds a master's degree in computer science and engineering and an MBA from IESE Business School, class of 2017, and describes 15 years of experience building data-driven solutions. Before Shayp he worked on Stylicist, a wardrobe assistant that recommended outfits based on how people wore their clothes. Shayp fits non-invasive dataloggers to existing water meters and runs the readings through anomaly detection to flag leaks and plumbing faults. The product line covers the 2ZERO software, the POLY4 hardware and 4IMPACT smart water financing, with devices assembled in Poperinge. The company reports deployment in more than 9,000 buildings and an average 22 percent reduction in water use. It raised 1.9 million euros in December 2020 from Signa Innovations, AMAVI Capital and finance&invest.brussels. In October 2025 de Hemptinne received IESE's 40under40 award as the entrepreneur with the most social impact.

Done ✔️ Next time we'll aim for even more efficient ! 😉 Working with large international companies is the best segway for scaling your impact as a startup 🚀. For two main reasons: 1. They are complex, but they help you improve your processes.

- Founders are told never to step away from the business. Zineddine Wakrim and I just did. Both of us, at the same time. Between installations in Italy and Spain and the first module of IESE Business School’s Foundations of Scaling in Barcelona, we were away from the office for a good while. At IESE, we joined 40 founders from 17 nationalities and 34 companies, all working on the same question: 🚀 what needs to change in a company to enter a new stage of growth? My answer, after this trip: focus and self development For
- Speed meetings sound like a bad idea on paper. 🤔 Short slots, a timer, and a room full of CEOs who all have a company to talk about. But for anyone at C-level, it works. With our schedules, I’d rather have a short slot than no time at all! This week I joined the B Corp CEO Speed Meeting at @TheMerode in Brussels, hosted by @B Lab Benelux. It was one morning of back-to-back conversations with founders and leaders from across the Belgian and wider Benelux B Corp community. Shayp has been a certified B Corp since 2022. It’s easy to
- Will the European Union finally address water leakage ⁉️💦 Yesterday, the President of the European Commission, Ursula von der Leyen, stated: " European pipes lose almost one in every four litres. Mostly through leakage. What a waste. So we will put forward a new European Water initiative. Because water is precious. " Water is indeed precious ... it's an understatement !! For people, for businesses for nature ... The problem is, it's still priced as if it were abundant. And most of that waste never shows up on a bill. It just
- I've done countless speeches on stage, but I still get a little nervous every time. Anyone else? I was giving yet another one at PropTech Connect and could talk about the invisible pain that water causes in buildings. We're protecting buildings at Shayp, but more importantly we're saving water: something I care about deeply, especially for next generations' future. So every time I talk about it, I want to get it right. I had some fantastic conversations at the event Huge thanks to my colleagues Benja Raice Felho, Artemy Voroshilov,
- Our economy runs on water, and the Rhine just proved exactly how much. On August 17, 2026, the gauge at Kaub, the river's shallowest choke point, read 5 cm. Twenty below the previous record, set in 2018. A normal summer reading there sits around 225 cm. ❓What the numbers mean: The gauge measures water level against a fixed historical reference point, not the riverbed. What it does capture precisely is the trend and the threshold that actually matters for shipping. Somewhere around the 40 cm mark, loaded cargo barges stop being
- 30+ billion litres saved: what AI water monitoring looks like for building portfolios. That's what I'll be unpacking on stage at PropTech Connect Europe. We'll get into how real-time consumption data, asset by asset across a portfolio, changes what's possible for asset managers and sustainability leads, and what it actually takes to get there. 🗓️ September 9th, 2:30 PM 📍 Innovation Stage, 1st floor InterContinental London - The O2 Can't make the session?
