What GoldSim does
GoldSim Technology Group, headquartered in Issaquah, Washington, develops and markets GoldSim, a Monte Carlo simulation software platform for dynamically modeling complex systems in engineering, science, and business. The product is a hybrid simulator that superimposes discrete events onto continuously varying systems, supporting hierarchical top-down model construction through an influence-diagram graphical interface. The core engine is complemented by five extension modules (Financial, Reliability, Contaminant Transport, Distributed Processing, and Dashboard Authoring), a free runtime viewer (GoldSim Player), and a Python integration bridge (GSPy) that connects to EPA-standard water modeling tools (EPANET, SWMM, MODFLOW) and optimization libraries (PuLP).
The company serves environmental systems engineers, engineered systems modelers, business analysts, academic researchers, and government agencies across more than 60 countries, with a customer base exceeding 600 commercial and government organizations including NASA and the Washington State Department of Ecology. Revenue is generated through perpetual software licenses, annual maintenance subscriptions (which gate free basic technical support), and fee-based advanced technical support sold at US$200 per hour in pre-paid 10-hour blocks. Academic institutions receive discounted licensing under a dedicated program. Distribution is direct via the company website with consultative enterprise sales and trial downloads.
In March 2026, GoldSim was acquired by Datacor, a software company serving engineers, process manufacturers, and chemical distributors that also owns CHEMCAD and Applied Flow Technology pipe flow tools. The acquisition is positioned to provide additional resources for product investment and customer experience improvements while preserving GoldSim's brand, product, and support operations.

GoldSim product offering
Product offeringCore offering
GoldSim develops and sells Monte Carlo simulation software for dynamically modeling complex systems in engineering, science, and business. The platform combines continuous system dynamics with discrete event simulation, supported by specialized extension modules for financial modeling, reliability analysis, contaminant transport, distributed processing, and custom dashboard authoring. It enables organizations to quantitatively represent uncertainty and evaluate alternative designs, plans, and policies through probabilistic predictions.
Product overview
GoldSim is a unified simulation platform consisting of a core Monte Carlo simulation engine with specialized extension modules. The core GoldSim software provides dynamic, probabilistic modeling capabilities for complex systems across engineering, science, and business applications. Extension modules add domain-specific functionality: the Financial Module enables probabilistic financial analysis; the Reliability Module supports failure probability modeling; the Contaminant Transport Module simulates environmental pollutant movement; the Distributed Processing Module accelerates computation via parallel processing; and the Dashboard Authoring Module enables custom interactive user interfaces. GoldSim Player provides free runtime access to pre-built models. The platform also supports integration with external tools (EPANET, EPA SWMM, MODFLOW, Python) via DLL bridges and the GSPy Python interface for extended capabilities. GoldSim is developed by GoldSim Technology Group, which was acquired by Datacor in March 2026.

GoldSim competitors and assessment
Company assessmentDirect peers
- ExtendSim: Simulation platform supporting discrete event, continuous, and agent-based modeling with strong industrial and process-engineering adoption. Comparable to GoldSim in supporting complex hierarchical models and stochastic analysis, though with a more general-purpose positioning and different module structure.
- Arena Simulation (Rockwell Automation): Discrete event simulation and process modeling software widely used in manufacturing, logistics, and healthcare. Comparable to GoldSim in offering hierarchical, probabilistic modeling for engineered systems, with deeper traction in industrial process optimization and a larger corporate parent.
- Oracle Crystal Ball: Excel-based Monte Carlo simulation and predictive modeling tool originally developed by Decisioneering and now owned by Oracle. Direct overlap with GoldSim in probabilistic forecasting and uncertainty quantification for engineering and business analysts, although distribution is via a much larger enterprise software incumbent.
- Simul8: Visual discrete event simulation platform targeted at process improvement, healthcare, and manufacturing. Comparable to GoldSim in providing hierarchical probabilistic simulation with domain extensions, though focused on operational/throughput use cases rather than environmental and infrastructure modeling.
- AnyLogic: Multi-method simulation platform combining agent-based, discrete event, and system dynamics simulation with Java/Python extensibility. Closely comparable to GoldSim's hybrid simulation engine and enterprise/government customer base, with broader modeling paradigms and a stronger cloud/SaaS posture.
- Palisade @RISK: Industry-standard Monte Carlo simulation add-in for Microsoft Excel, used by risk analysts and engineers to model uncertainty in spreadsheets. Closely comparable to GoldSim's Monte Carlo simulation capabilities, distribution model (perpetual license + maintenance), and target audience of risk-aware technical professionals.
Broad incumbents
- MathWorks MATLAB and Simulink: Dominant numerical computing and model-based design platform used across engineering and science. Comparable to GoldSim in serving engineers who need probabilistic and dynamic simulation, but with a much broader scope, mature cloud offering, and far larger installed base and pricing power.
- COMSOL: Multiphysics simulation platform used for engineering R&D across mechanical, fluid, chemical, and electrical domains. Comparable to GoldSim in addressing complex engineered systems with specialized add-on modules, but anchored in physics-based FEA rather than probabilistic system dynamics.
Others
- HEC-HMS (US Army Corps of Engineers): Public-domain hydrologic modeling software developed by the U.S. Army Corps of Engineers and widely used by government water agencies. Comparable to GoldSim's hydrology and water resources applications, though not a direct competitor as it is freely distributed and limited to rainfall-runoff simulation.
Emerging players
- RiverWare (CADSWES, CU Boulder): River basin modeling and water resources simulation tool used by utilities, Reclamation, and academic institutions. Comparable to GoldSim's water resources modeling use cases, particularly the Contaminant Transport Module, but with narrower domain focus on river/reservoir operations rather than general systems simulation.
