Meet some of the people behind Gurobi

The computational progress in linear and mixed integer programming over the last twenty years has been nothing short of remarkable, enabling business, scientific and other applications that literally would have been unapproachable just a few short years ago. The Gurobi founders have been at the forefront of these developments.

The Gurobi team is committed not just to providing the best technology now available, but to continuing to push forward the frontier of optimization solution capability.

Duke Perrucci

Chief Revenue Officer

Duke Perrucci, Gurobi Chief Revenue Officer

Mr. Perrucci has 25 years of experience in roles spanning sales, marketing and analytics. Prior to his role at Gurobi, he held the position of CRO at Cambridge Analytica – a predictive analytics firm. Here he built the commercial practice in North America by helping companies drive better advertising through the use of artificial intelligence. Before Cambridge he spent 8 years in martech with FocusVision. Here he built a global sales organization across 6 continents and 10 offices. Prior to FocusVision, Mr. Perrucci spent a total of 9 years at Information Resources Inc. (IRI) working in various analytic consulting roles across the entire PepsiCo enterprise. After the first 4 years at IRI, he decided to gain experience on the brand side and moved into analytics at Unilever. Before long he secured a position in brand management working on the Bertolli business – a $400 million brand in the United States. When IRI came calling again, it was an offer too good to pass up – running the Pepsi Cola and Quaker businesses out of PepsiCo’s world headquarters in Purchase, NY.

Before this journey, Duke earned a BA in Classical Civilization from Fordham University. While en route, he earned his MBA from Cornell University.
