We build the infrastructure that makes digital documents trustworthy, verifiable, and automatable — at every step of the process.
In a world where businesses operate digitally across geographies and jurisdictions, the signature on a document is only as trustworthy as the system that verifies it.
Most signing solutions stop at the moment of signing. DN Deliveries starts there and builds a complete verification infrastructure around every signed event — ensuring that documents remain trustworthy long after they leave the signing system.
We believe trust in digital documents should be cryptographically verifiable, server-anchored, and accessible to anyone — not stored in an email thread or reliant on a static file attachment.
Every product we build is designed to establish and maintain verifiable trust in digital documents — from the moment of signing through any future verification.
Manual steps are the enemy of scalable operations. DNFlow eliminates the gap between signing and action — connecting document events to your business systems automatically.
DNVerify API means any system can verify any DN Deliveries certificate. We don't lock verification behind our own UI — we expose it as infrastructure.
Operating out of Germany, we design every system with GDPR compliance, EU data residency, and transparent processing as baseline requirements — not afterthoughts.
Our engineering philosophy: every piece of data has provenance, every action has an audit trail, every document has a verifiable origin.
Every product we build exposes its core functionality as an API. This makes DN Deliveries embeddable into any existing system without rebuilding workflows.
Certificates are server-anchored documents. The PDF you receive is a human-readable view; the source of truth lives on our servers and can be queried at any time.
DNFlow treats every signing event as a trigger. Business logic lives in automation rules, not custom code — reducing integration time from weeks to hours.
Hash-based integrity checking isn't a premium feature — it's in every certificate, every time. There is no "basic" tier that skips security.
