When 11 insurance startups sat down to work for the first time in the Stilts Building last January, they held the hopes of an anxious industry. They’d come to Hartford for the city’s inaugural, and untested, accelerator program, the Hartford InsurTech Hub. The second group, announced this week, will be walking into something more established. With CVS committing to keep Aetna in Hartford, and other corporate giants looking to tech startups for big ideas, the once-lethargic industry has regained some of its insurance stature. In November, the National League of Cities and Schmidt Futures recognized Hartford as “the country’s premier destination for insurance technology.”
