About the company

Written by GovTribe AI ·

Rarisrex, LLC, a limited liability partnership and child of parent company Uncomn LLC, operates as a subcontractor to federal primes on IT and business application development work, with two recent sub awards under Accenture Federal Services and a single prime award under a GSA vehicle. The vendor's federal footprint is minimal and recent: three total awards across 2021–2025, with combined potential value of $2 million and $621 thousand in obligated dollars to date.

Rarisrex is headquartered at Scott Air Force Base, Illinois, alongside parent Uncomn LLC. No SBA designations (8(a), HUBZone, SDVOSB, WOSB, or other set-asides) appear in the source. The vendor's award portfolio shows 67% sub-award activity and 33% prime participation. Customer concentration is split between the Department of the Treasury Internal Revenue Service (two awards, both sub tasks under Accenture) and GSA Federal Acquisition Service (one prime award, $2 million potential value). The two Treasury sub awards, dated June 2024 and December 2025, address tax account processing and taxpayer experience intake re-compete work within the IRS Enterprise Development Operations Services vehicle. The GSA prime award sits on the Multiple Award Schedule.

On the GSA Schedule labor portfolio, Rarisrex and parent Uncomn LLC carry ninety-seven active labor categories spanning IT helpdesk, functional analysis, cloud engineering, and cybersecurity roles at rates from $34.78 per hour (IT Helpdesk Specialist I, bachelor's degree, no clearance) through $329.29 per hour (Cybersecurity Solutions Architect VI, master's degree, 20 years experience, mentor-priced under parent T-Rex Solutions, LLC). The spectrum indicates a blended capability portfolio in cloud infrastructure, application development, and security analysis.

Service Contract Inventory data captures only one record in FY2024, reflecting 0.2 FTEs of sub-contracted work against the $150,000 reporting threshold. This minimal SCI footprint reflects the vendor's nascent federal contracting presence — the first award in source data dates to May 2021, and recent activity (December 2025) suggests the vendor is actively pursuing work but has not yet scaled. The corporate structure names T-Rex Solutions, LLC as a mentor firm on the GSA Schedule, indicating a relationship beyond parent-child ownership.
