👋 Hello – My conversation today is with Jared Semik, founder of Eternium Aerospace, a long-range, zero-emissions aircraft development company, focused on sustainable transatlantic flight.

​

A multi-service military aviation veteran with three global deployments, Jared began his career in the Marine Corps in 1999. He is an aerospace research and development engineer with over 20 years of experience working with next-generation zero-emissions aircraft systems. His expertise spans R&D, aircraft systems engineering, program management, talent and supplier development, and corporate partnerships for several global industrial and aerospace corporations. He has been ultimately responsible for the program development of 14 proprietary technologies.

Jared holds a BS in Mechanical Engineering and Business Administration and has earned two U.S./PCT patents for aircraft systems and propulsion.
​
As you’ll hear in our conversation, Eternium is a multi-decade endeavor, and Jared has taken a highly strategic and intentional approach to building the company. This includes fostering local partnerships with organizations like NASA Glenn and implementing a tiered development strategy that stages the creation of commercially viable milestones—such as the power unit, superconductive motor, and ultimately, the Archangel aircraft.
​
Jared has an insightful perspective on risk and is a strong believer in the philosophy that “nothing ventured, nothing gained” and that “all the best things in life are on the other side of one’s fear.” This philosophy extends beyond his business and into his personal pursuits, which include rock climbing, mountaineering, SCUBA diving, skiing, and more.
​
We discuss the challenges of achieving aircraft range and efficiency, the intersection of creativity and engineering, the technological breakthroughs required for zero-emission travel, the importance of long-term thinking, and much more. Please enjoy this fascinating and educational conversation with Jared Semik.

With Love,

Jeffrey
