About Antimony LLC
Antimony LLC, a women-owned small business based in Chantilly, Virginia, holds a single GSA Multiple Award Schedule (MAS) contract as a prime contractor, offering quality engineering, IT customer experience strategy, and program management labor services to federal civilian agencies on a time-and-materials basis. Antimony is a self-certified small disadvantaged business and SBA-certified Women-Owned Small Business operating as a subchapter S corporation.
The vendor's footprint in federal contracting is nascent. Antimony's sole award is a GSA MAS contract issued February 24, 2025, with a $475 thousand ceiling and performance through February 23, 2030. The contract spans ten active labor categories covering quality assurance, IT customer experience and strategy, and program management roles, with hourly rates ranging from $73.72 (entry-level Quality Engineer with two years' experience) to $157.54 (Engineer III with five years' experience). All positions require a bachelor's degree; no security-clearance roles are currently offered on the schedule. Representative mid-tier roles include IT Customer Experience Strategist ($88.87 per hour), Program Management Specialist I through III (spanning $88.87 to $131.29 per hour), and Engineer II ($105.03 per hour), all requiring three to five years of relevant experience. The labor portfolio aligns to PSC IT And Telecom — Business Application/Application Development Support Services (Labor) and NAICS Other Computer Related Services, positioning Antimony as a source for civilian IT staffing augmentation on a commercial-rate basis rather than a specialized defense contractor or complex systems integrator.
Customer concentration is singular: GSA Federal Acquisition Service is the sole customer agency represented in the source data, accounting for 100% of awards and combined potential value. No subcontractor awards or subcontractor relationships appear in the footprint. Activity comprises one award in 2025. The vendor presents as an early-stage federal contractor with a single Schedule contract and no visible prime or sub work history in the source window.
