The startup scene in United States

Danbury is represented in StartupBlink’s September 2026 city list at ranks #543 globally and #147 in the United States; StartupBlink says its ranking algorithm uses total investment, employee count, and quarterly website traffic. These are publisher-attributed rankings, not a verified roster of companies founded or operating in the city.

Several documented companies connect Danbury to physical-product manufacturing. The City of Danbury says LesserEvil began in the city in 2012, and the company reports that its products are manufactured at its Danbury headquarters. The City reported more than 650 LesserEvil employees across the region in July 2026. Imperial Electronic Assembly identifies Danbury as its founding city in 1988 and describes itself as a privately owned electronic contract manufacturer; in July 2026, the City described the company’s investment of more than $23 million as planned.

Cadenza Innovation says it was founded in Connecticut in 2012. In November 2022, reporting described the company consolidating its Wilton and Bethel operations in Danbury and licensing technology to global manufacturers. A 2020 News-Times report attributed more than $500,000 in financing to the Connecticut Innovations venture fund; that is a historical amount. Danbury Hackerspace reports that it was founded in 2012 and lists 3D printers, prototyping tools, a mockup studio, and coworking space among its facilities. In 2016, the News-Times reported that founders of Bethel-based Noteworthy Chocolates used Hackerspace equipment to test their product idea.
