about us

Dr. Harold Hess is the visionary founder of Enduralock, a pioneering company at the forefront of innovating technologies that improve aircraft assembly and maintenance times and facilitate space logistics through In-Space Servicing Assembly and Manufacturing (ISAM).  With a background as a Board-Certified Neurological Surgeon and an inventor with over 60 patents worldwide, Hess has seamlessly transitioned from revolutionizing medical devices to redefining how critical components function in extreme environments.

Frustrated by the lengthy surgery and recovery times he witnessed while specializing in neurosurgery, Dr. Hess co-founded Spinal Simplicity and invented an interspinous-interlaminar fusion device with a proprietary high-durability locking mechanism that endured 5 million cycles of compression and 5 million cycles of torque without loosening. Recognizing the broader industrial applications of his technology, he founded Enduralock to tackle one of the most persistent challenges in aerospace – creating fasteners that can withstand high vibrations, thermal fluctuations, and the demands of in-orbit assembly.

Hess’s strategic vision has propelled Enduralock into the aerospace and defense sectors, ensuring its technology remains adaptable across industries. The company’s flagship innovations include high-vibration resistant fasteners and an advanced self-aligning nut plate system. These technologies eliminate the need for traditional safety wiring, reducing lifecycle costs while enhancing structural reliability. The company is currently advancing satellite docking systems and adapting its fasteners for vision-based intelligent systems, paving the way for fully autonomous in-orbit assembly.

As the space industry evolves, Hess remains committed to innovation, focusing on solutions that will enable the servicing, upgrading, and construction of satellites in orbit.
