About Avantix, LLC
Avantix, LLC is a for-profit limited liability company based in Fairfax, California that specializes in providing software solutions and technical support services to the U.S. federal government, particularly the Department of the Navy. The company has maintained federal contractor status since its SAM.gov registration in May 2004 and has established itself as a key technology partner for naval agencies through its primary offering, the COLTS (COTS Logistics Tracking System) program management suite. Avantix delivers maintenance, technical support, and software licensing services that support critical logistics and tracking infrastructure across naval operations, with a business model focused on providing specialized software solutions to defense agencies.
Avantix's federal contract work demonstrates a concentrated focus on COLTS-related services delivered primarily to two Naval commands: Naval Sea Systems Command (NAVSEA) and Naval Information Warfare Systems Command (NAVWAR). As a prime contractor, Avantix has received six purchase orders ranging from $30,000 to $150,000, including contracts for COLTS software maintenance (multiple awards from NAVSEA in 2023, 2024, and 2025), COLTS technical support services (awards from NAVWAR in 2022 and 2025), software license and maintenance renewal services (NAVSEA, May 2030), and license reinstatement and maintenance support (NAVSEA, June 2022). None of these prime awards utilized set-aside designations. Beyond its prime contracting role, Avantix has served as a subcontractor to major defense firms including Lockheed Martin Corporation, Northrop Grumman Systems Corporation, General Dynamics Global Force LLC, Science Applications International Corporation, Textron Systems Corporation, and Serco Inc., with sub-award work spanning computer software provision, technical support services, product delivery, and material purchases. The company's sub-contracting activity has been consistent, with awards documented from 2021 through February 2025, demonstrating sustained engagement with the defense industrial base across multiple prime contractor relationships.
