Our Software

Our flagship GoldSim software package is based on technology developed over a period of over 25 years. GoldSim has been used by and/or for a diverse set of customers and clients, including government agencies in over 10 countries (such as the US Department of Energy, NASA, the Nuclear Regulatory Commission, and the California Department of Water Resources), research laboratories (including Sandia National Laboratories, Los Alamos National Laboratory, the Paul Scherrer Institute, and MIT), and commercial organizations worldwide, including Bechtel, BHP Billiton, Caterpillar, CH2M Hill, ConocoPhillips, Mitsubishi, Newmont Mining, Northrop Grumman and Rio Tinto.

Our Customers

GoldSim currently has thousands of users around the world (including nearly 200 academic institutions in 40 countries), and our user-base is growing rapidly. The software is very actively developed, and continues to evolve in response to customer's needs.

Our Company

Our history is in the civil and environmental engineering arena, but GoldSim was designed from the ground up as a general-purpose, probabilistic simulation framework. As a result, the software is now being used in a wide variety of applications, ranging from long-term business planning for manufacturing companies to operational models of mines and power plants.

A Commitment to Customer Service

We pride ourselves in providing prompt and extensive support to our users, and are committed to ensuring that each installation of our software is successful and adds value to the customer. Our support ranges from email and phone support to address installation and questions regarding basic use of the software to customized on-site training and consulting.

A Commitment to Our Partnership Network

Our objective is to provide our customers with complete end-to-end solutions to address their simulation needs. Our strategy is to keep the GoldSim Technology Group focused on building great simulation software and supporting the technical aspects of building effective GoldSim models. To provide other dimensions of complete solutions, we maintain close relationships with partners, including consulting firms with industry specific expertise, software providers who offer complementary software, and resellers that provide local sales support and product demonstrations.
