CEO/CTO

Mark Zangari

Zangari leads Quantellia’s Scalable Solutions division, where he leads the World Modeler development team as well as partnering on enterprise-scale modeling projects. Before joining Quantellia, Zangari spent 15 years as CTO for a spatial GIS company, where he specialized in providing solutions to utilities and telecoms. A physicist by training, Zangari’s papers on cosmology are still referenced today.

As co-founder and CEO of Quantellia, Zangari continues to advance the practice of Decision Intelligence by developing the platforms, methodologies, and ecosystem that enable organizations to operationalize the discipline at scale.

Learn more in Zangari’s Introduction to Decision Intelligence, Including Decision Simulation for the Enterprise Webinar, where he shows how to build a decision model for a complex enterprise project, why data isn’t enough, how to connect data to business outcomes, and the role of simulation in connecting technology to business outcomes and actions.

Chief Scientist

Dr. Lorien Pratt

A machine learning pioneer, Pratt has delivered applied machine learning solutions since 1988. She co-edited Learning to Learn, wrote LINK: How Decision Intelligence Connects Data, Actions, and Outcomes for a Better World, co-authored The Decision Intelligence Handbook and leads Quantellia’s machine learning consulting division.

Today, Pratt is widely recognized as the leading voice in Decision Intelligence, helping organizations connect human expertise, AI, and causal reasoning/models to improve complex decision-making. Through her writing and educational programs, she continues to advance practical approaches that make AI more transparent, explainable, and action oriented.
