Nexus Solutions

What Nexus Solutions does

Nexus Solutions, Inc. is a privately held industrial software company founded in 1996 in Kingwood, Texas (originally as Nexus Engineering, rebranded in June 2004), that develops real-time diagnostics software for process and power plant operations. The company's core product is the rtOpx (Real-Time Operations Excellence) platform, a modular enterprise software suite deployed through the NexusOzopx delivery engine. The platform comprises four integrated modules: rtSCDx for sensor validation (17 sensor diagnostics, 30 controller diagnostics), rtEPMx for predictive equipment performance modeling (covering valves, pumps, exchangers, fired heaters, and distillation columns), rtKMx for knowledge management (deploying PSM documents and senior operator expertise), and rtIAx for integrated real-time operator advisory. The architecture is built on Microsoft .NET with native XML and OPC connectivity for integration with existing DCS and historian systems.

Nexus Solutions serves nine process and power industry verticals: Refining, Petrochemical, Chemical, Power Generation, Gas Pipeline, Upstream, Pulp & Paper, Pharmaceuticals, and Brewing. The platform addresses operational pain points including equipment reliability, sensor accuracy, throughput optimization, and the loss of institutional knowledge as senior operators retire.

The company operates a small organization of 11-50 employees under founder Jack Stout III (President). It generates revenue through subscription/recurring enterprise licensing of the rtOpx platform, with quote-based pricing on enterprise agreements covering implementation, training, third-party integration, and maintenance packages. Distribution is exclusively through a network of 5 authorized regional agents across 4 continents (Asia Pacific in Korea, China, Malaysia, and Taiwan; South America in Argentina; plus reach into Central America, Europe, and Canada). The firm holds a 2001 strategic alliance with Emerson and maintains registered trademarks on rtOpx and Nexus Oz. No external funding rounds, acquisitions, or parent ownership are disclosed.
