Auditors who build software.

Stephan Hoppe studied business informatics and is a German public auditor (Wirtschaftsprüfer) and tax advisor. At DATEV he developed modules for IT audit, so he knows audit software from the inside. After university he worked in audit and then moved to REWE Group.

There he audited in group internal audit, then took charge of the group-wide internal control system and most recently headed Group Financial Reporting with around 70 staff.

He then joined a mid-sized audit firm as managing director and partner and co-founded Oreamnos.

What runs through every stage: understanding, structuring and automating processes. That is what he brings to ore.

Dmitri Steinbach studied media informatics and, after early projects in 3D modelling, quickly found his way into software development. On the team he is known as “the professor”: one keyword is enough and he explains off the cuff where a technology comes from and how it works. He works through every new framework until he knows what is behind it.

For companies he has done almost everything from IT administration to custom software. He has built ERP systems from the ground up and translated the operations of entire companies into lean processes. Corporate groups still bring him in as a consultant and have him train their developers, especially in working with AI.

At Oreamnos he is responsible for the architecture of ore, the tech stack and development. Especially with AI, it helps that he gets to the bottom of new technology quickly. On top of that come IT and software audits.

Thorsten Klein trained as an industrial clerk and studied business administration at TH Köln, specialising in financial accounting, management and controlling. After positions at Audi and PwC he joined EY, most recently as manager and authorised signatory (Prokurist).

At EY he led audits in an international environment as the responsible auditor, many of them with SOX compliance and PCAOB requirements. From years of practice he knows what audit processes must look like to meet even the strictest regulatory requirements. Having also worked in mid-sized firms, he knows both sides of the profession.

At Oreamnos he makes sure that every feature of ore complies with the ISA and stands up to a quality control review. He ensures that new requirements reach ore immediately, and he is responsible for professional testing and professional development.

Maria A. Wimmer has been Professor of E-Government at the University of Koblenz since 2005 and heads its E-Government research group. She is one of the best-known voices in her field internationally and is closely connected across Germany and Europe.

She studied computer science at the University of Linz and then researched in Rome and Siena how safety-critical systems can be designed holistically. From 2000 she led research and consulting projects on e-government in Linz. In 2004 and 2005 she worked at the Austrian Federal Chancellery on interoperability, electronic signatures and the training of public sector staff.

With Oreamnos she founded Holistic Systems Development GmbH, which advises public authorities on e-government. For us she is the theoretical backbone and makes sure our work stays at the forefront of research.

Cedric Pauken is a doctoral candidate in information systems at the University of Koblenz, focusing on e-government. He researches generative AI and large language models, and how to standardise and prepare heterogeneous data for such models. He is currently developing an AI assistant that checks procurement documents for construction works.

He contributes to the German standards for electronic procurement: XRechnung, XBestellung and XKatalog. In his master's thesis he specified XKatalog as the national standard for e-catalogues.

At Oreamnos he advises public authorities on e-government together with Andreas Schmitz, and the Landesbetrieb Mobilität Rheinland-Pfalz on AI. Like Andreas, he works on our research project to make the AI in ore safe and verifiable, so that our audit processes deliver the quality an auditing standard demands.
