About us

We are an innovative European company that provides a collaborative solution to the recurring problem of increasing administrative burden imposed by compliance standards and regulations. As such, we have developed a B2B information and services network that is both collaborative and open, and which allows companies to share legal documents.


Our aim is to connect companies, simplify their day-to-day business and secure customer-supplier relations at a European level. Our ambition is to develop a “once for all” solution and enable companies to share their up-to-date administrative documents with customers across Europe; once and for all.

By developing a new interoperability standard that interconnects existing platforms from different countries, we propose a true “Once for All” solution for all contractors aiming to do business with European public or private entities.

“We want to help businesses become more competitive by reducing non-core tasks. We achieve this through value-added services that are made possible by world-class technology

Today companies are hampered in expanding beyond the border by focusing on a single market, sector and country. We are convinced that many of these obstacles can be overcome through standardization.

To make the market more open, flexible and efficient at the European level, it is our plan to bring everyone together – competitors, suppliers, contractors and the public sector – through an open standard.

We cooperate with all market participants to achieve this goal.”
