Compliance by design: EU-first, GDPR- and EU-AI-Act conformity, audit-ready data flows, open source, and sovereign deployment. We help start-ups, scale-ups, SMEs, associations, NGOs and the public sector ship AI knowledge assistants, RAG chatbots, AI email agents and voice agents – on EU-hosted infrastructure your team can run without us.
We build specific things, not slide decks. RAG chatbots over your own documents. AI email agents that draft replies for human review. Voice agents and structured transcription. Internal knowledge assistants for staff and members. AI avatars for video content at scale.
Default stack: n8n in Berlin, Qdrant in the EU, Azure OpenAI via Microsoft EU Sovereignty, plus open-source EU alternatives like Mistral and Milvus on request.
Internal knowledge assistants
RAG chatbots over your own documents, with cited answers.
AI email agents
Classification plus drafted replies, reviewed by a human before sending.
Structured transcription
Voice to formatted reports, e.g. for German Pension Insurance reporting.
Member portal AI
Chat-based discovery alongside category filters.
Document triage
Classify and route incoming forms or requests to the right team.
Workflow automation
n8n-based orchestration around the AI step, with full audit trails.
1. Identify
A one or two-day AI use case workshop where we map your real processes, score candidate AI use cases against impact, feasibility, data and risk, and pick the one to build first. You leave with a project sketch and a written summary within 48 hours.
2. Prototype
In four short sprints we build a working version of your top use case on EU-compliant infrastructure. Working software at the end of every sprint. Real users in front of it as soon as possible.
3. Implement
We hand over a low-code architecture with documentation so your non-technical team can operate and extend the system. Optional ongoing support.
Public sector and municipal administrations
Under EU AI Act and GDPR constraints. Procurement-ready. We have delivered under Civic Coding and for leading industry associations.
NGOs, associations and impact organisations
Small teams, full inboxes, knowledge-heavy member portals. The shape of work we already ship for a leading donation platform, a leading member network and Multilang Socialmap.
SMEs and innovation / operations teams
With internal documentation, repetitive knowledge work, and the appetite to ship a working prototype rather than commission another strategy deck.
A leading member network – RAG knowledge chatbot in production for 1,000+ members inside HumHub. Delivered in four sprints on n8n + Qdrant + GPT-4 via Microsoft EU sovereignty. Operated by a non-developer team.
GDV (German Insurers Association) – AI Knowledge Assistant over tens of thousands of policy documents, supporting 400+ member insurance companies and the policy questions of an industry that manages over 500 million insurance contracts.
Tannenhof Berlin-Brandenburg – Civic Coding-funded AI transcription pilot for therapy sessions on EU-hosted infrastructure, with output formatted for German Pension Insurance reporting. Started with a premortem session that mapped legal, security and user-acceptance failure modes before any code was written.
A leading donation platform – AI email agent classifying enquiries and drafting replies with mandatory human review, in pilot on N8N and Azure OpenAI.
Civic Coding – AI consultation across 100 social-impact projects under Germany's federal initiative.
Through the development of our Custom GPT, our employees and members can find relevant information much more easily and quickly, and rediscover sources and long-forgotten folders.

AI creates a new kind of intelligence that opens up exciting possibilities for every person and every organization to achieve more. When approached responsibly and with a spirit of curiosity, it can lead to truly great things – as we have experienced when working with N3XTCODER on the AI for Impact Challenge.
