The Connecticut Business Landscape
Connecticut's small geography belies its economic density — the state hosts one of the highest concentrations of hedge funds and private equity firms in the world, clustered in Greenwich and Stamford along the I-95 Gold Coast corridor. Connecticut is known as the 'Insurance Capital of the World,' home to Aetna, The Hartford, and dozens of major insurance and financial services companies.
The aerospace and defense industry is deeply rooted: Pratt & Whitney manufactures jet engines in East Hartford, Sikorsky builds Black Hawk helicopters in Stratford, and General Dynamics Electric Boat designs nuclear submarines in Groton — providing tens of thousands of high-paying manufacturing jobs. Yale New Haven Health and Hartford HealthCare anchor a major healthcare sector.
