Crux OCM is a venture capital backed seed stage start-up on a mission to enhance control room operations in the $87.5 trillion dollar per year oil and gas industry to enhance safety and efficiency through autonomous capabilities. Although we are a young company, our team is comprised of industry veterans that have already made their mark in control system, commissioning, and advanced process control. In two short years we have progressed from concept, to MVP, to commercial-scale POC ‘s. Our key short term KPI is to add new logos via facilitating additional POCs. Crux OCM was born with the belief that control room operators should have better tools to perform their daily jobs. Control room operations directly impact safety, environmental, and bottom line revenue for energy operating companies.
