(0 review)Future-proof digital platforms for complex organisations
Blastic builds and maintains the digital platforms that complex organisations run their business on. We work across five enterprise CMS and DXP platforms: Sitecore, Kentico, Umbraco, Prepr and Kontent.ai. That matters more than it sounds. It means we can recommend the platform that fits your case rather than the only one we know. Founded in 2012, we work from Kontich, Ghent, Rotterdam and Amsterdam. Our Sitecore practice holds Silver partner status with nine certified professionals, two Sitecore MVPs, and specialisations in Content Hub and Experience Platform. We are a Kontent.ai partner and a Kentico Solution Partner. Clients include Hyundai, AXA, Renson, Versele-Laga, Melexis, Kingspan, De Watergroep, Xerius and Novy. Largely manufacturers, insurers and public organisations running multi-brand, multi-country platforms with a long horizon. What we are asked for most: replatforming and migration between CMS platforms, headless and composable architectures, B2B commerce and customer portals, and WCAG / European Accessibility Act compliance. We also offer Sovereignty as a Service, for organisations that need their platform and data to remain under EU jurisdiction. Most of our client relationships are measured in years, not projects. Think, create, accelerate.Looking for work in C# (C-Sharp) DevelopmentLocated in Kontich, BelgiumFrom €1,000 for C# (C-Sharp) DevelopmentWorked in Travel & Leisure (+10)Speaks English, Dutch(+2)11-50 membersIn the Pocket
(0 review)We ship what others pitch.
Most digital agencies sell you a phase. A strategy deck. A design sprint. A dev team. Then they hand you off and wish you luck. We don't work that way. In The Pocket is a 200-person digital product studio that owns the entire journey, from the boardroom question to the product in your customer's hand. Strategy, design, engineering, data, and AI. One team, no handoffs, no excuses. Since 2010, we've shipped over 500 products for organisations like Barco, Telenet, and BMW. Not prototypes. Not decks. Real products, used by 12.5 million people every year to pay, travel, work, and stay informed. From our studios in Belgium and the Netherlands, we partner with companies that treat digital as a core business capability, not a side project. In a market flooded with agencies that either think or build, we do both. And we stay until it works.Looking for work in C# (C-Sharp) DevelopmentLocated in Ghent, Belgium (+1)From €1,000 for C# (C-Sharp) DevelopmentWorked in Household Products (+7)Speaks English, Dutch(+3)201-500 membersI-Web

The company prioritises stability, long-term maintainability and transparent project management. Using proven technologies like .NET and Azure, it offers clients predictable performance and the ability to scale when needed.
