Hartford is Connecticut's capital and has long been known as the "Insurance Capital of the World," with insurers such as Aetna, The Hartford and Hartford Steam Boiler headquartered in the city. Beyond insurance, the local economy leans on services, education and healthcare, and the Greater Hartford metro ranks among the higher U.S. regions for per capita income. Technology investment has grown as well, including an Infosys innovation hub focused on insurance, healthcare and manufacturing. Marketing agencies in the Hartford area, many based in suburbs such as Avon and Glastonbury, commonly serve financial services, insurance, healthcare, manufacturing and public-sector clients, alongside regional consumer brands.
