Fuse Leadership

Sumner Hunt Lee

Founder & CEO

Sumner founded Fuse with a vision to deliver critically needed capabilities to the warfighter through application of Design Thinking processes. He leads the company by aligning the team to a Noble Cause of “Advancing warfighter capabilities with elegant, user-focused communications, networks, and software systems.” By combining deep operational experience of veteran operators with exceptional engineering expertise inside Fuse, Sumner has assembled a team that successfully applies cutting-edge technology to real operational issues. The combined experience and expertise of the Fuse team has enabled successful transitions from research and development to products in the hands of our customer users.

Sumner started his career as a naval aviator. After graduating from the US Naval Academy, he graduated first in his class from flight school and flew H-46 helicopters through two deployments with the HC-11 “Gunbearers” out of San Diego. Later, he accepted a position leading the SPAWAR Systems Center Pacific airborne networking team. He was a plankowner of the Joint Tactical Edge Networking working group, and while at SPAWAR, he won three ONR Rapid Technology Transition projects, co-wrote the technical plan for the $70 million CABLE Joint Capability Technology Demonstration, and transitioned two airborne networking programs from projects into programs of record.

Before founding Fuse, Sumner worked as Director of Business Development at RKS Design, an internationally recognized strategy development and product design firm, where he came to appreciate the value of human-centered design. Sumner has been awarded a patent for a multi-enclave networking solution, an Exemplary Achievement Award from SPAWAR, and previously he served as a lieutenant in the US Navy. He also served in a leadership position at Centurion Boats, the Hindu Kush Ski Patrol, and founded M-WERX LLC. Sumner holds an MBA from the University of Southern California.
