Experience Is The Difference
Tough Stump Technologies is a Service-Disabled Veteran Owned Small Business that fuses nearly 60 years of combined experience with the latest technologies relevant to small unit tactics. Tough Stump Technologies continuously excels in developing and implementing simple solutions to the complex problems our clients face. U.S. federal/state government agencies, private and non-profit organizations, and special operations groups across the globe benefit from our experiential proficiency with tactical communication readiness, situational awareness toolkits (e.g. ATAK), and the latest remote sensing and SUAS technology to collect and process ultra-high resolution (1.5” per pixel) imagery.
Our practical expertise in utilizing advanced comms equipment, payload-capable drones, and terrestrial photogrammetry in austere and disconnected environments is surpassed only by our ability to teach clients how to harness these technologies and integrate them appropriately into their operations.

Paul Julian is a 20-year U.S. Air Force veteran with a deep background in logistics, including the last seven years spent supporting USSOCOM.

When he’s not keeping operations running like a well-oiled machine, you can find him chasing a golf ball across the nearest fairway or keeping up with his boys, who ensure life stays lively off the clock
