For clients
Different challenges.
Tailored solutions.
A ready-made product cannot cover every need. For clients, we build websites, specialist applications and integrations that fit their existing workflows.
Web & platforms
Websites backed by a working system
Django platforms with content management, e-commerce and CRM. Shared technology, with separate spaces for each client.
Management & organisation
Specialist applications that connect the work
Management systems for cemetery lighting and hearing care: from subscriptions and maintenance to device records and appointment scheduling.
AI & integration
New capabilities for existing systems
Telephone assistance connected to FileMaker and local AI for IT workflows: finding information, classifying requests and preparing the next steps.
