REX Information

REX is building the DecisionOS™ for high-stakes, complex systems. Most enterprise software helps organizations see what happened, predict what might happen, or automate predefined rules. REX answers a different question: What is the optimal decision to make right now? Our DecisionOS™ evaluates the full Decision Space™—thousands or millions of possible actions, constraints, tradeoffs, and downstream consequences—to identify the path most likely to produce the Optimal Outcome™. We’re starting where decisions have measurable economic consequences: energy. REX runs a 30-day assessment at no cost, evaluating the exact decisions an organization actually made. We move forward only if DecisionOS™ demonstrates that it would have made or saved the customer money. From energy and logistics to healthcare and national security, our thesis is simple: The next generation of AI won’t just predict the future. It will help decide what to do about it. REX — The DecisionOS™ for the world’s most consequential decisions.
