Lumen is the operating system for digital agencies that runs your projects, clients, and invoicing on infrastructure that never leaves the EU. It puts first-class EU tax and compliance — Slovenian atypical-taxpayer rules, e-invoicing, eIDAS-signed documents, and AI Act transparency — at the core, not bolted on.
EU-sovereign by design
Hosting, payments, email, and AI all run on EU providers — no US-jurisdiction service in the path of your clients' data.
Self-hostable with GPU
Deploy to your own Linux box with one Docker Compose, and run the AI on-premise when you want full control.
AI-native, not bolted-on
Agents, semantic search, and natural-language queries are part of the data model, not an afterthought.
MCP-native
Reach your agency data from Claude, ChatGPT, and your editor through authenticated Model Context Protocol servers.
Built for EU compliance
GDPR data-subject requests, eIDAS-signed invoices, e-SLOG / Peppol e-invoicing, and Slovenian atypical-taxpayer mode out of the box.

Frequently asked questions
Where does our data actually run?
The PII path is 100% EU-sovereign, hosted with Hetzner in Germany and Finland, with no US-jurisdiction service in the path. You can also self-host it on your own hardware.
Is the compliance complete?
The VAT engine, GDPR data-subject requests and AI transparency are shipped today; Peppol dispatch and eIDAS signatures are on the roadmap. We keep an honest feature matrix and state maturity plainly.
Can we trust it for production billing yet?
It's in active development as a closed-beta MVP, so we recommend a pilot or early-access engagement. It isn't intended for unsupervised production billing yet.
