Overview

I didn't set out to build a SaaS company. I set out to fix something that was broken.

10 years ago Influencer marketing had become this weird mix of gut instinct, spreadsheets, and crossed fingers. Brands were spending serious budgets with almost no visibility on what was actually working. So together with my co-founder Cathy, we built Stellar and later more solution under the Stellar Tech umbrella to change that. We've grown the hard way: through acquisitions, market-by-market expansion, and a lot of hard-won market knowledge. Today we operate across Belgium, France, the Netherlands, and Germany, helping brands and agencies run influencer programs that are measurable, scalable, and responsible.

Beyond the platform, I sit on the Steering Committee of the Influencer Marketing Alliance (IMA) and on the Board of Women in Tech Belgium. Because building industry standards matters as much as building the product. I'm also obsessed with what AI is doing to our space right now - not in a hype way, but in a "this is actually changing everything and we need to talk about it honestly" way. I write and speak about it regularly especially when linked with influencer marketing.

Outside of work: I'm a mum (the most humbling leadership role I've ever had), a runner who uses early morning kilometers to think clearly, and the proud owner of Marvel, a golden retriever who has absolutely no respect for my schedule. I believe these things make me a better entrepreneur, not despite the chaos, but because of it.

If you work in influencer marketing, AI, or you're just building something in Europe and want to compare notes... I'm always happy to connect.
