How Connecticut’s digital economy grew
Hartford Fire Insurance Company is founded
Started with $15,000 in working capital. It survives today as The Hartford, still headquartered in the city that became known as the insurance capital of the world.
Colt’s armory: the birthplace of American mass production
Samuel Colt’s first venture failed by 1842. He rebuilt after a 1,000-revolver order from the Texas Rangers, and by 1855 his Hartford armory — its blue onion dome still standing today — was mass-producing genuinely interchangeable parts, assembled on standardized gauges by relatively unskilled labor. By the Civil War it employed 1,500 workers turning out roughly 150,000 firearms a year.
The armory doubled as a de facto engineering academy. Alumni Francis Pratt and Amos Whitney left to found their own machine-tool company in 1860; other Colt-trained machinists went on to found Cadillac, Lincoln, and Warner & Swasey. In 1925, aircraft-engine designer Frederick Rentschler got his company’s name, capital and shop space from that same 1860 tool company — launching Pratt & Whitney Aircraft, still headquartered in East Hartford today.
Insurance, submarines and helicopters
Hartford’s insurance cluster traces to 1810, and the identity has held for over two centuries — The Hartford and Travelers are both still headquartered there. Meanwhile Connecticut’s shipyards and aircraft makers kept delivering genuine world firsts: Electric Boat’s USS Holland (1900) and USS Nautilus (1954, the first nuclear submarine), and Sikorsky’s VS-300 (1939, the first practical helicopter).
The Hartford
Founded 1810 as Hartford Fire Insurance Company — still headquartered in the city.
Electric Boat
Groton, since 1899 — built the Navy’s first and first nuclear submarines, still building them today.
Sikorsky Aircraft
Stratford, since 1929 — flew the first practical helicopter in 1939, now a Lockheed Martin subsidiary.
How Connecticut businesses buy websites
Connecticut is small and dense, but Hartford, Bridgeport, New Haven and Stamford are genuinely different markets — corporate insurance HQs, defense manufacturers, and everyday local trades sit close together but sell to very different customers.

Why FastSites works here
A state that invented the interchangeable part understands the value of getting the standard version right, fast, rather than custom-building everything from scratch. A one-page site, live in days, at a published price, is that same idea applied to a small business’s website.
