How c:node works

Your organisation plus the world outside. Every answer evidenced.

You ask in your own words. c:node reads your systems, checks them against law, registers and market and verifies every statement at its source. Only then do you see the answer.

1 · Your organisation

c:node reads your systems – with your own access.

Microsoft 365 and Google Workspace are ready to use; our connection team sets up Lexware, Pipedrive, Salesforce and others on request. Only what you approve is enabled.

2 connectors ready to useOAuth · API key

2 · The world outside

The c:node Graph knows law, registers and market.

EU and German federal law, commercial register, public tenders, lobby registers and sanctions lists. All checked against the official source and continuously updated. Publicly viewable at graph.c-node.ai.

3 · Link & verify

c:node puts both sides side by side.

Your file meets the applicable rules. c:node shows step by step what it has checked. On its own, each source looks harmless – together they form the picture.

4 · Evidenced answer

Every statement comes with its citation.

The answer names your file and the provision. Anything that cannot be evidenced, c:node marks as open. Better “I don’t know” than an invented number.

With any model

You decide which model may answer.

Claude, GPT, Gemini, Mistral or open models on your servers. For each question, c:node picks the right one from the models you allow. The check at the source stays the same.

How do you arrive at an evidenced answer?

@Lena, can we onboard Nordwerk Logistik GmbH as a new client?

I'm checking both sides – your file and what applies:

Client file read (4 documents)
Company name, seat and registration number matched against the commercial register
Beneficial owners identified in the transparency register
EU and UN sanctions lists checked
Obligations under the German Anti-Money Laundering Act (GwG) checked

Onboarding possible – but only with enhanced due diligence.

Company and commercial register match
Owner is based outside the EU – § 10, § 15 GwG
Similar name on the EU sanctions list – clarify before onboarding
