Connecticut New Business Leads: new LLCs with NAICS industry codes (daily)

Get newly registered Connecticut businesses from the official Connecticut Secretary of the State Business Registry open data on data.ct.gov (public domain), updated daily. About 5,000 new businesses a month, and unlike most state registries, each one comes with the NAICS industry code the owner chose, so you can pull "new construction companies", "new restaurants" or "new dental practices" directly.

Each result has the business name, account number, business type, registration date, NAICS code and industry, home state of formation, city, state, ZIP and business street address.

No browser, no proxies, no login. Runs take seconds.

Who uses this

• Suppliers, insurers and equipment dealers targeting new companies in one industry (e.g. NAICS 23 construction, 722 restaurants).
• Business banks, accountants, payroll and bookkeeping firms reaching companies in their first weeks.
• B2B SaaS and lead-gen agencies building fresh Connecticut lists by town or ZIP (Stamford, Hartford, New Haven, Greenwich).
• Economic development and market researchers tracking new business formation by industry.

Privacy by design

• No emails and no personal names. Business email, survey email, owner-demographic flags and agent data are never requested.
• Businesses only. Rows whose name has no business designator (LLC, Inc, Corp...) are dropped, except nonprofit corporations.
• Apartment-style addresses are withheld (city/ZIP stay).
