Christian Frisch

Christian Frisch

 Managing Director
Q-Auditor & Automotive Core Expert

A Saarland native with a lot of experience in barbecuing - that is also competence!

After 18 years of professional experience (OEM, 1st & 2nd tier suppliers), he returned to the origins of his automotive career out of love for his home country. As Audimus founder, he has successfully demonstrated his courage several times since 2015. But also in his daily dealings with customers, partners and his employees, he demonstrates his diverse skills and passionately sets the direction.

Christian Frisch has been one of the best consultants and auditors in the automotive field for years. In his private life, he enjoys being out in the "fresh" air. He courageously climbs the highest peaks with his splitboard and mountain bike at the appropriate time of year. Even with Audimus, he still wants to go high!


Ulf Winkler

Ulf Winkler


Ulf Winkler came to quality via production planning in the automotive supply industry. In addition to his enthusiasm for production and manufacturing processes, he discovered his passion for supplier quality management. From 2014, he initially worked as a VDA 6.7 auditor. Since 2016, he has been a certified VDA 6.3 process auditor with global experience. For him, audits are not an end in themselves, but ideally part of a progressive customer-supplier relationship for mutual benefit. Understanding the customer and making him fit for the audit are his guidelines in consulting. Since 2023 he has been active as a VDA trainer in training on the topics of Automotive Core Tools (ACT) and qualification as a VDA 6.3 Process Auditor.

For balance and energy, he goes to the gym for strength and endurance training. And if that's not enough, he's an avid hiker in the Alps or follows his long-standing passion to experience Great Britain. 


Jan Schumacher

Jan Schumacher

Dipl. Ing.


Jan Schumacher is one of our consultants and the expert for FMEA. He already developed his passion for the topics of risk analysis - and minimisation - during his mechanical engineering studies (2003) and completed his diploma thesis in the automotive supplier industry on the topic of FMEA. He himself says: "thinking through complex systems and processes is his passion." 

State of the art technology and science, that is his theme. For this reason, standing still is not an option for him either.

In his free time, he covers longer distances on his bicycle and boldly spends his holidays "backpacking".


Stefan Liebig

Stefan Liebig


Stefan Liebig has a good rapport with our customers and takes care of comprehensive support. He always strikes the right note, and not just because he likes to bravely give his best in karaoke sessions in his spare time. In addition to striking the right note, Stefan Liebig also finds the right solution for our customers, from the initial enquiry to the final settlement. In his private life, he is passionate about playing pool and looking after his four-legged pelt-nose, his dog.
