Oli

For more than fifty years, OLI has helped engineers predict and solve the world’s toughest chemistry problems. Grounded in first-principles science and proven in the field, our work delivers clarity when it matters most. That pursuit began with solving failures others could not explain and continues today with a focus on turning scientific understanding into predictive insight. Our platform integrates simulation, cloud automation and embedded AI to meet the demands of modern industry. Each model is grounded in proven chemistry and built to translate complex interactions into practical insight. The results reflect decades of validation and the continuous refinement of our frameworks, ensuring that every analysis supports confident, data-driven action. At OLI, we enable our users to make decisions with confidence. Our proactive, partnership-driven approach safeguards their most valuable assets and ensures reliability in the most demanding environments. Our mission is not to provide data, but to provide understanding and predictive power that turns chemistry into foresight. Our clients include leaders in energy, mining, manufacturing, and water management who depend on OLI to ensure operational reliability and long-term performance. They come to us for insight that moves beyond calculation, giving engineers the understanding to act before problems occur. Headquartered in Parsippany, New Jersey, OLI operates globally through its software, consulting, and collaboration with academic and government institutions. Each partnership reflects a shared goal: transforming chemical complexity into clarity that strengthens performance, protects assets, and supports a more sustainable industrial future. Learn more at
