What w11k does

W11K GmbH is a privately held German software agency headquartered in Esslingen am Neckar, with regional offices in Stuttgart and Cologne. Founded originally in 2000 (as iMEDIC) and re-established under the W11K brand in 2015, the firm specializes in building modular B2B customer portals (Kundenportale) and custom web applications for German Mittelstand companies across manufacturing, automotive, e-commerce, healthcare, and regulated industries. Service offerings span consulting, UX/UI design, full-stack development, and managed cloud hosting, with Angular and React as core frontend competencies and Node.js, Python, Java, and AWS Lambda as supporting backend technologies.

The company's product surface combines a partially modularized Kundenportal platform (configurable modules for product catalogs, configurators, order management, surveys, and account management) with bespoke Individualsoftware engagements. An in-house training sub-brand, theCodeCampus, sells Angular, TypeScript, and software testing courses directly to corporate clients. Cloud hosting and ongoing operations provide recurring managed-services revenue tied to the software W11K ships. Customers include named enterprises such as Trusted Shops, Mercedes-Benz, Daimler Mobility Services, Festo, K15t, and Klinikum Esslingen, alongside mid-market and startup clients.

The go-to-market is sales-led and consultative: free two-hour "Portal-Check" sessions with CTO Roman Roelofsen convert into fixed-price pre-projects (Vorprojekt) with money-back guarantees, then larger multi-year project engagements. The firm is owner-managed by co-founders Jan Blankenhorn (CEO) and Roman Roelofsen (CTO), with Felicitas Proelß as Prokuristin/People & Culture. With roughly 30 employees, an average tenure of 7 years, and no external funding, W11K is a profitable lifestyle-scale boutique operating exclusively in the German domestic market.
