  • Greg Jarrett

    CEO & Partner

    Commencing his aviation career in 2000, Greg has extensive international experience through roles with DHL Global Logistics, TNT Same-Day, Air Charter Service (London & Dubai), Adagold Aviation and NetJets Middle East. These varied roles included management and procurement of aviation services under Government/Defense contracts, and procurement of charter aircraft in VIP, Cargo and Commercial transport roles. Greg’s early leadership of the Dubai office for Air Charter Service (ACS) was instrumental in ACS becoming one of the major global charter brokers in the Middle East region.

     

    Greg founded STACK.aero in 2014, building the company’s original technology solution himself. Since then, both the company and its suite of product offerings has grown, with Greg now working as project lead on major accounts. Highly skilled in .NET/C#, JavaScript and APEX programming languages, Greg has built a nexus between these technical skills and his industry experience. Having worked with countless Business Aviation Operators, Government, Defense and VIP Customers, Greg ensures that STACK.aero products operate as tools of competitive advantage.

     

    Favoring a holistic approach, Greg has found the most effective path to organizational efficiency is via automation and data analysis and has directed all STACK.aero development efforts accordingly. Greg is committed to providing enduring technology to the aviation industry that is dedicated to maximizing growth potential and providing micro and macro solutions.
