Stewart is a graduate of the US Air Force Academy’s 38th class - the Class of 1996.

Born in Service.
Built to Win.

We started in the late 1990s, when Stewart, fresh from serving his country as a USAF officer, was working for a huge multinational contractor and was fed up with having to explain, from his operational role, that what the proposal teams promised the USG wasn't physically possible. The senior leaders at this multinational were tired of his complaining and challenged him to win the next bid, so he did, and never looked back.

Starting out in the Middle East, he quickly made a name for himself in GovCon circles and started attracting like-minded talent. The team was always fluid, but the processes were set in stone. Honed and sharpened over more than two decades of battle, the GCA Proposal Development Methodology has led to billions in contract awards.

Today, our team spans the globe and offers 24/7 coverage. We cover every US Combatant Command, geographic and functional. Our proprietary QMat™ and CMat™ are the heart that drives our success. We operate with a fierce dedication to the mission and an unwavering candor. We're here to make sure you win. Like it says on the door - we win US Government Contracts. Period.

The Team Behind the Results

Stewart brings over 25 years of hands-on US Government contracting experience spanning countless industry sectors and multiple theaters of operation. He has personally captured and directed contracts totaling in the billions, with deep expertise in construction, logistics, fuel distribution, food services, warehousing, and transportation across the Middle East, Africa, and beyond.

Director Strategic Partnerships & Client Services

Cinzia oversees the strategic backbone of GCA's engagements. Her deep study of human psychology and behavior makes her a formidable advocate at the US Government negotiating table - and a ruthless qualifier of every opportunity she touches. Cinzia doesn't just assess whether a client can win a bid; she ensures they can execute at a level that makes the follow-on contract virtually inevitable. Relentless in building the relationships that matter, dogged in protecting the clients she represents.

How We Operate

Six commitments that define every engagement, every deliverable, and every relationship.

Integrity Above All

We tell the truth, especially when it costs us. Clients feel it immediately and understand our intent. If a client is not ready to win, we say so. We refuse to sell false hope. That integrity protects our results, our reputation, and our relationships.

Precision is Power

Details win contracts. We demand 100% technical compliance. Every requirement gets tracked. Every word carries intent. Every response is exact. Our team feels pride in the craft because precision is not perfectionism. Precision is how we win.

Win Relentlessly

Winning is what we do. Our client-side team finds the right bid for you to win. Our proposal teams craft unbeatable proposals. Our operational teams make sure your performance now guarantees follow-on work later. Every department plays to win, every day, in everything we do.

Always Be Communicating

No surprises. No silence. No missed details. We communicate early and often, with clients and with each other. Risks, shifts, wins, and lessons learned are shared before anyone has to ask. That builds trust and reduces execution stress.

Compassionate Candor

Radical honesty, delivered with respect. We speak hard truths to elevate people. Our feedback makes clients and teammates stronger, sharper, and more prepared to win. This standard creates confidence, not fear.

Mission-Level Ownership

We act as if missions and lives depend on our work, because in many cases, they do. We own outcomes, deadlines, and quality. We show up fully and take responsibility for what happens on our watch.
