About the company
Goldsim Technology Group LLC is a for-profit limited liability partnership based in Seattle, Washington, that sells proprietary scientific simulation and modeling software to federal agencies as a prime contractor competing under full-and-open, noncompetitive sole-source procurements. The company operates exclusively as a prime across 43 federal awards with no subcontract work in the source data. Goldsim does not hold federal IDVs, GWACs, or BPAs; instead, it receives purchase orders and task orders directly from customer agencies for software licenses, upgrades, and maintenance support.
Goldsim's federal capability portfolio is narrowly specialized: GoldSim Pro, a quantitative risk and performance-assessment modeling platform with specialized modules for radionuclide transport, contaminant fate-and-transport, and cost estimation. The company's primary federal customers are in nuclear and environmental remediation domains. The Nuclear Regulatory Commission Central Office anchors the customer base with 12 awards carrying $700 thousand in combined potential value, centered on recurring annual license renewals for GoldSim Pro with Radionuclide Transport Module and DP Plus modules supporting the NRC's decommissioning site assessments and high-level waste repository performance evaluations. The Department of Energy Office of Environmental Management holds 3 awards ($490 thousand combined potential value) for GoldSim software support and maintenance tied to nuclear waste cleanup and site remediation programs. The Department of Energy's National Nuclear Security Administration placed 2 awards ($450 thousand), and NASA Ames Research Center placed 1 award ($173 thousand). Five additional agencies account for the remaining customer footprint.
The award footprint is sparse: forty-three awards spanning from 2004 to April 2026, with activity concentrated in the 2000s and early 2010s and recent years showing minimal issuance (one award in 2021, one in 2022, one in 2026). Combined potential value across all awards stands at $3.8 million, though obligated dollars totaled $5.5 million. The NRC and DOE together account for approximately 49% of combined potential value. Procurements are classified under NAICS 513210 (Software Publishers) and PSC 7A20 (IT and Telecom Application Development Software with Perpetual License) as the predominant categories, reflecting Goldsim's identity as a proprietary software vendor rather than a custom development or integration services firm.
