Founder & Owner’s Background

Cemocan “Gemo” Yesil is a Combat Veteran, Aerospace Engineer, and a Global Defense Business Development executive with 20 years of experience. As a dual-rated U.S. Air Force pilot, he has flown Combat Rescue helicopters and Tactical Airlift jets in Iraq, Afghanistan, Africa, and S. America.

After managing Fortune 500 engineering teams on multiple $2B+ programs at Sikorsky/Lockheed Martin and scaling his EdTech startup nationally, Gemo has served as CMC Electronics' Global Sales & Strategy Director, Gecko Robotics' Head of Defense Business Development, and HABCO Industries’ VP of Sales & Marketing. He launched Bastion Atlas in 2024 to assemble a team of revenue growth experts and scale their impact across the global Aerospace & Defense industry.

He remains proudly connected to his alma mater (MIT), retains an active security clearance, and — as a personal passion — continues to manage national STEM Education initiatives.
