We build the infrastructure that finally makes real estate knowledge accessible

docunite grew out of a simple observation: real estate companies hold vast amounts of knowledge — but it sits in documents that know nothing about each other.

The docunite DNA

docunite is a dedicated team of specialists from IT, software development, and the real estate industry. We know the specific challenges of the industry and use our extensive experience to give you a platform tailored precisely to your needs. Our team combines IT security, software development, and usability to deliver an intuitive and powerful solution.

How docunite came to be

Built on more than 20 years of experience in the real estate industry

Patrick Penn, Founder and CEO, worked as an IT specialist in the real estate industry — not as a consultant, but as someone who built the systems himself and saw the problems every day.

His impression: in every company there were thousands of documents that knew everything — contracts, addenda, handover protocols. But this knowledge was invisible, because none of it knew about the rest, let alone talked to it.

In 2017 he founded docunite — and with it a data room that understands real estate. Not folders and drives, but structure based on industry logic.

"In every company, there is knowledge locked away in documents that no one can find. We changed that."

— Patrick Penn, Founder and CEO

But structure alone is not enough. Documents also need to be intelligent — not just filed away, but connected. In 2024, docuspine was born: an AI-Backbone that builds a persistent knowledge graph from documents. Every processed document makes the system smarter. No forgetting, no starting over.

Today, Patrick Penn and Mark Scharpenack run the company together. Patrick with the vision, Mark with the closeness to the product. docunite is self-funded: no venture capital, no investors. A deliberate choice. We build what the industry needs. Not what a pitch deck promises.
