What Enduralock does
Enduralock, LLC is a privately held aerospace technology company founded in 2014 and headquartered in Lenexa, Kansas. The company develops In-Space Servicing, Assembly, and Manufacturing (ISAM) technologies, with a product portfolio centered on three core systems: OneLink™, a universal docking connector combining mechanical linkage for in-space transportation with interfaces for refueling, data, and power transfer, featuring active misalignment correction for autonomous robotic docking; OneCatch™, a deployable in-space capture mechanism for satellites and orbital debris using 95% COTS materials with only 3 actuators; and OneBuild™, a robotic end effector for in-space assembly integrating with self-aligning nut plates and a Zero-G Retention Disc. Supporting these are patented mechanically locking vibration-resistant fasteners that survive 10x aerospace vibration standards and self-aligning nut plates that accommodate up to 30° of angular bolt misalignment with minimum 25 reusability cycles.
The underlying technology is rooted in patented high-durability locking mechanisms originally developed by founder and CEO Dr. Harold Hess, a Board-Certified Neurological Surgeon and inventor with over 60 patents worldwide whose prior medical device fastener demonstrated 5 million compression and torque cycles without loosening. The company holds AS9100D and ISO 9001:2015 certifications, reflecting aerospace-grade quality management standards. Its go-to-market is engineering-led direct enterprise sales targeting satellite manufacturers, government space agencies, and orbital logistics providers, with revenue generated primarily through hardware product sales, government contracts (SpaceWERX), and potential licensing of patented technologies. Pricing is quote-based with multi-year contract terms, and marketing is concentrated on industry events, SpaceNews earned media, and direct engineering outreach.
Enduralock operates with a small team of approximately 10 employees and has secured a $1.25M SpaceWERX contract for OneLink™ development (May 2025), a Letter of Intent with Space Ocean Corp to standardize docking interfaces (October 2025), and product validation through Arkisys' 1G robotic ground test facility (December 2025). Both OneLink™ and OneCatch™ achieved 'awardable' status through the DARPA ERIS Marketplace in June 2026. Revenue is not publicly disclosed, and the company's first orbital product deployment is scheduled for early 2027 on the Arkisys Cutter satellite, with a second deployment planned for mid-2028 on the Arkisys Port Module.
