"I have had the pleasure of working with Lorenz for over four years, during which time we have collaborated on numerous projects related to INCAR connectivity for North America."
"Lorenz is an extremely hardworking and dedicated colleague who consistently goes above and beyond to ensure that projects are successfully completed. His knowledge of mobile network infrastructure is truly impressive, and he has a great knack for moving projects forward and making sure everyone is on the same page."
"In addition to his technical skills, Lorenz is also an excellent resource when it comes to GDPR issues. He has a deep understanding of the regulations and is always happy to help colleagues navigate the sometimes complex landscape of data protection."
"One of the things I appreciate most about Lorenz is his approachability. He is always willing to lend an ear and offer advice or assistance when needed, and his calm and focused demeanor makes him an excellent colleague to work with."
"In short, I highly recommend Lorenz for any position related to mobile network infrastructure, GDPR, or INCAR connectivity."

"I worked with Lorenz in a long-term automotive connectivity project — he was the responsible lead for our North America OEMs on MNO side."
"Lorenz is in large-scale technical projects a picture book example of a Swiss army knife: He is an extremely motivated project manager, able to communicate and negotiate with any level of stakeholder, always ready to help fixing short-term issues as well as overtaking tasks that everybody else is ignoring. He is very tech-savvy, which allows him to understand complex problems and solve them on 3rd level by himself instead of forwarding the issues to others. And he also has a broad understanding on product management methods and gives always valuable input for product UX."
"Besides that, Lorenz is at the same time a very caring colleague who offers a listening ear and a persistent fighter for progress — to move on with activities."
"I highly recommend Lorenz without restrictions — he is an impeccable reinforcement for any team."
— Gordon Ewe, Senior Manager at valantic · LinkedIn, April 28, 2023

"His strategic vision, coupled with operational excellence, ensures projects align with broader business goals, making him an invaluable asset."
"It is always a pleasure working together with Lorenz."
— Christoph Greb, Entwicklungsingenieur Connected Car · LinkedIn, December 13, 2023
"I worked closely with Lorenz for around one year on a complex Automotive Connectivity project in my role as Product Manager. While he was formally engaged as a Senior Consultant Automotive IoT, he effectively acted as the central point of contact and de-facto project lead, playing a key role in driving the project to successful completion."
"Lorenz demonstrated outstanding ownership, deep domain expertise, and a high level of professional maturity. He successfully led complex topics across commercial, contractual, legal, and technical domains, consistently providing clarity, structure, and momentum."
"Equally strong are his stakeholder and communication skills: issues were handled pragmatically, alignment was created across teams, and problems were solved, not escalated."
"I would gladly work with Lorenz again in a senior project leadership, customer success, or delivery role and strongly recommend him for complex, high-responsibility engagements."
— Fabian Imsiecke, Product Lead at Mercedes-Benz Digital, HHL Alumnus · LinkedIn, January 15, 2026
"I worked with Lorenz Schirmer in the context of a complex project at the intersection of automotive connectivity, digital processes, and technical hardware integration, where he acted as the main contact on the telecommunications side."
"Lorenz combines deep technical expertise in mobile networks and connected vehicle architectures with a strong ability to translate complexity into executable, reliable solutions. He quickly establishes clarity in ambiguous situations, aligns stakeholders across technical and organizational boundaries, and drives topics to concrete, binding outcomes. His contribution had a measurable impact on speed, quality, and overall project progress."
"What clearly distinguishes Lorenz is his execution strength: he does not stop at concepts or coordination but actively ensures implementation, resolves issues pragmatically, and takes ownership where others hesitate. The collaboration was consistently professional, focused, and results-oriented."
"Lorenz Schirmer is a highly reliable expert and leader for demanding projects in automotive connectivity and digital integration."
