During his tenure as EVP, Kunz oversaw tremendous growth and margin expansion through various organic initiatives and strategic acquisitions. In his various roles at TÜVR, Kunz focused on customers in a wide range of end-markets including consumer electronics, telecommunications, medical, automotive, and renewable energy.

“Holger is a proven world-class leader, and I am very excited to welcome him to GRL,” said Johnson Tan, Granite River Labs’ co-founder and CEO.  “I’ve worked with Holger for many years and been consistently impressed by his success in building technology-driven businesses and teams around the world.  Holger’s entrepreneurial drive and expertise in leading cross functional organizations supporting complex technical needs make him the perfect fit to expand our service capabilities and create more value for our customers.”

“Granite River Labs has a sterling reputation for its testing expertise in digital connectivity and charging technologies, an impressive roster of globally-recognizable clients, and a strong leadership team,” said Kunz. “Following a fulfilling career with TÜVR, I am excited to partner with GRL and SFW Capital and take on a more entrepreneurial role.
