Daily Delta: New Business Entities (CO, CT, OR)

You sell something every new company needs — business insurance, bookkeeping, payroll, a bank account, a website. The best moment to reach a founder is the fortnight after they file, while they are still choosing vendors and nothing is locked in. Miss that window and you are asking someone to switch rather than to start.

So you want yesterday’s filings, every morning, for the states you cover. Not a list someone resells you three weeks late.

The manual way, and what it costs

This data is genuinely open. Colorado, Connecticut and Oregon each publish their business-entity registry as a Socrata dataset, and you can filter and export from those portals yourself without paying anyone. If you work a single state, go and do exactly that — bookmark the dataset, sort by formation date, download the CSV. It costs nothing and this actor has little to offer you.

The cost appears when you cover more than one. Each state is a separate portal with its own column names: what Colorado calls the formation date field is not what Connecticut calls it, entity-type codes differ, and addresses are shaped differently in each. So “new companies this week across my territory” becomes three exports plus a normalisation script you now own and maintain — every morning, indefinitely.

The faster way

Multi-State Corporate & Business Entity Registry (CO, CT, OR) queries all three registries and returns one normalised shape.

{
  "states": ["CO", "CT", "OR"],
  "sinceDate": "2026-07-06",
  "maxResults": 500
}

sinceDate is what makes this a delta rather than a dump: only entities formed on or after that date come back. Set it to yesterday and schedule the run daily, and each run returns only what is new. Set it to the first of the month and you get the month so far.

What comes back

{
  "state": "CO",
  "entity_id": "20251665680",
  "entity_name": "KYLDERON MIST VALLEY LLC",
  "entity_type": "DLLC",
  "status": "Good Standing",
  "formation_date": "2025-06-16T00:00:00.000",
  "jurisdiction": "CO",
  "principal_address": "660 Willow Wood Ln",
  "principal_city": "Delta",
  "principal_state": "CO"
}

Field	Why it matters here
formation_date	How old the company is, to the day — the entire basis for a timed outreach window
entity_name	Who to address
entity_type	DLLC, corporation, non-profit — filters out forms you do not sell to
status	Good Standing, or not
principal_address / _city / _zip	Territory routing, and a mailing address
agent_name	The registered agent — often a formation service, not the founder

The field that closes the loop is formation_date. Sort by it and the list is ordered by how warm the lead is.

What you’d do with it

Schedule it daily with sinceDate set to yesterday and push the rows into your CRM as new leads, keeping the formation date as a custom field. Route by principal_state to the right rep. Filter entity_type down to the forms you actually sell to — most B2B sellers want LLCs and corporations and little else.

Worth knowing

Three states, not fifty. Colorado, Connecticut and Oregon, because those are the ones confirmed to publish an official Socrata business-entity registry. More are added as they are confirmed — plenty of states advertise business-entity data without publishing it in a queryable form.

A registered agent is not a founder. agent_name is frequently a formation service or a law firm shared by thousands of companies. Treat it as routing metadata, not a contact.

No phone numbers or email addresses. State registries publish addresses, not contact details. This gives you the company and the address to enrich from — nothing more.

Filing date is not opening date. A company can form months before it trades, or form to hold an asset and never trade at all.
