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 with his wife and two children. 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!


Hermann Paul

Hermann Paul


Information security expert from the very beginning. After 17 years of responsibility for QM in the automotive supply industry and plenty of expertise in start-up protection and crisis management, Hermann Paul started as a consultant, trainer and certification auditor for IATF 16949 & ISO 27001 back in 2004. From then on, the topic of information security became more and more a personal passion.

We find it courageous that he will take on responsibility as operational managing director at Audimus in 2022.

But also in his private life, Hermann Paul always strikes the right note, shows perseverance and skill.

So it's no surprise that he continues to successfully complete marathons, can regularly be found golfing or eliciting his tones from his double bass on Contra C. 


Helmut Aschenbrenner

Helmut Aschenbrenner

Partner Consultant

As a long-standing, active member of the VDA working group on the topic of field failure analysis (2018), he is highly regarded as an expert and trainer. His expertise in this field is the result of 25 years of automotive experience, among other things. The last 9 years alone as global head of warranty at BROSE Fahrzeugteile. 

Helmut Aschenbrenner has always been a passionate competitive athlete. Since 2022, he has been responsible for the overall warranty business area at Audimus and takes on complex warranty problems for our customers as a sporting challenge. Courageous, we think! 

He also keeps moving in his private life with his family. Mountain biking, hiking or fitness in the gym. Mental and physical fitness are the basis for whatever challenges may come. 


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.


Jonas Rouenhoff

Jonas Rouenhoff


Jonas became aware of us after his training through a career orientation programme. He quickly recognised his passion for the processes and procedures at Audimus. He courageously decided to complete a part-time degree programme with us and expand his skills. In his free time, he enjoys playing football and watching American football, as well as being out and about with friends in our state capital.


Nadine Haßdenteufel

Nadine Haßdenteufel


She is actually a humanities graduate, but ended up in marketing due to her passion for social media and PR. For Audimus Consulting, she is out and about on the web, working with the whole team to come up with fresh and bold ideas for our social media channels and organising events. Besides marketing, she is interested in languages and literature, which all came together in her English studies.
