Just formed a business in Connecticut?

Before a lender reads your application, its verification system checks your state filing, your exact legal name and your domain against each other. Your business credit history only starts once an account reports it, so it's worth getting both right early.

Methodology

Counts are businesses registered with the state of Connecticut whose formation (registration) date falls in December 2025 and that appear on the state register in ListRiver's data as of October 12, 2026. Businesses already dissolved are not counted, so older months can drift slightly as records change. City and county refer to the business address on file. More in the methodology.
