Deloitte’s 2026 Technology Fast 50 lists Belgium’s fastest-growing technology companies, and Adhese is the only adtech company among them. It got there by building a privacy-first, omnichannel retail media platform for retailers and commerce media networks across Europe: one platform for websites, apps, newsletters and in-store screens, where the first-party data always stays with its owner.
“Our strategy of putting retailers and publishers at the forefront, and helping them keep full control of their data, has strengthened our position in the market over the past few years. We see our place in the Fast 50 as confirmation that we are heading in the right direction, and as recognition for our whole team. Next, we want to bring this approach to more media owners across Europe,” says Sven Marievoet, CEO of Adhese.
From retail media to commerce media
Retail media networks are one of the fastest-growing parts of advertising. Online retail media in Europe grew 16.7% in 2025 to €13.3 billion, according to IAB Europe’s AdEx Benchmark. And it no longer stops at supermarkets, from in-store screens to sponsored products in apps. A bank, a delivery app or a postal company knows its customers too, and brands want to reach them. The industry calls this commerce media and Adhese is fully ready to support it.
How Adhese makes advertising work without giving up privacy
Adhese sees privacy as the foundation of a lasting ad business. A company that keeps control of its customer data, its first-party data, keeps its customers’ trust, and that trust is what brands pay to reach.
It pays off commercially too. In the usual online ad chain, a large share of what a brand spends never reaches the company that shows the ad. Adhese connects media owners and brands more directly, through direct programmatic connections, so more of the budget stays with whoever owns the audience. See how it works.
How does Adhese keep first-party data private under GDPR?
Adhese acts only on its customers’ instructions, as a processor under GDPR that never owns their data. Each customer decides whether cookies are used at all, and campaigns can run cookieless. That’s why competing retailers can run on the same platform without seeing each other’s data. More on privacy and compliance and in the Trust Center.
