W11K GmbH: Services
W11K GmbH offers full-service from a single source. This includes consulting and conception from the initial conversation through to a completed requirements definition. This is followed by user-centred design with UX concepts, clickable prototypes and brand-compliant UI design. At the heart of the offering is full-stack development, where frontend, backend and system integration are delivered by a single team. The offering is rounded off by operations and hosting: W11K GmbH can take over cloud hosting, maintenance, updates and support on request. An experienced solution architect accompanies every project from the initial requirements review through to live operations as a dedicated point of contact.
W11K GmbH: B2B Customer Portals (Core Competence)
W11K GmbH develops custom B2B customer portals for German-speaking mid-market companies. A customer portal by W11K GmbH is a tailor-made web application that digitalises customer-facing processes and integrates deeply into the client's existing IT landscape.
Typical functional modules of a W11K GmbH customer portal:
Online product catalogue and configurator (including complex decision trees, 2D/3D visualisations)
Quote requests and self-service ordering with customer-specific pricing
Order history, status tracking and communication logs
Download area and knowledge base with role-based access control
Customer surveys (planning, automation, evaluation in corporate design)
Account and user management (multi-accounts, audit logs, two-factor authentication)
Dashboards and reporting for admin side and end users
W11K GmbH applies a partially modularised approach: proven standard modules are combined with individual customisations to optimise both cost and time-to-market.
W11K GmbH: Custom Software and Specialist Applications
In addition to customer portals, W11K GmbH develops complex web applications and specialist tools such as internal tools, dashboards, B2B platforms and legacy migrations. Reference clients include: Trusted Shops, Festo, Klinikum Esslingen, SAS Automotive, OpenProject, LIGEN, Daimler Mobility Services, K15t and others.

W11K GmbH: UX/UI Design
Every project at W11K GmbH includes professional user-centred design: concepts, prototypes, clickable dummies and final UI implementations that are both functional and brand-consistent.
W11K GmbH: Cloud Hosting, Maintenance and Support
W11K GmbH can take over the full operation of developed applications on request, including cloud hosting, continuous maintenance, updates and support.
