NextTraceENDE
A Berlin engineering studio for production AI.
NextTrace builds production-grade AI for European industries that have to be right — tax, healthcare, supply chain. Every recommendation traceable, every value sourced, every output reviewable. Berlin headquartered, EU-resident from day one.
Why
Most AI is built for demos. We build for audit.
- Production, not prototypeEuropean tax law, healthcare workflows, and supply-chain operations don’t tolerate “looks roughly right.” They need outputs a tax inspector, clinician, or auditor can verify. That’s a different engineering posture from “ship a demo and iterate” — and it’s the posture this studio is built around.
- Right beats fastWe move slow when correctness demands it; fast where it doesn’t carry regulatory or clinical weight. Judging which is which is the work.
- EU-resident, audit-gradeData residency, GDPR posture, and regulatory readiness are built into the architecture from the first commit — not bolted on at compliance review.
- Four products, one postureTaxioAI for German tax filing, NexDoz for diabetes insights, SCG for supply-chain compliance cases, Farnah for locally runnable native AI. Different industries, the same engineering bar.
Work
What we make.
NexDoz
Diabetes insights from seven device integrations — Dexcom, FreeStyle Libre, Withings, Oura, Whoop, Fitbit, Polar — with multi-provider AI routing. iOS TestFlight beta.
Read →SCG
Compliance case management for LkSG, CSRD, and UFLPA. Hash-chained evidence ledger, DMN rules, BPMN workflows, SAP/Oracle/D365 connectors. Closed pilot cohort.
Read →Farnah.ai
A locally runnable native AI engine for open-weight models with an agentic CLI. Persistent Spectrum memory carries context across sessions; OpenAI-compatible serving, bounded tools and MCP, multimodal input, and eval-gated native training are built in. Pre-release.
Read →Behind it
Fifteen years on systems that had to be right.
The studio’s engineering posture isn’t a positioning slogan — it’s the career of the people behind it. 15+ years on business-critical backend systems: industrial, B2B, Berlin-based. Symfony, domain-driven design, distributed systems. Seven of those years inside heavy industrial operations, where the cost of a wrong answer was measured in production hours.
Auditable AI for regulated European industries is the natural extension of that work.
