Who buys a list of brand-new companies

A company incorporated this week needs a bank account, an accountant, insurance, a domain, a website, software and an office. Filter by sicCodes to get only the industries you sell to, and by registeredOfficeAddress to get only your patch.

Why this is one request per day

Companies House caps any results download at 5,000 rows — and gives no signal when it has truncated. Asking for a whole week in one query returns exactly 5,000 rows and looks like a complete answer.

So this Actor always slices one request per day. Measured on the verified run: 1–3 September returned 8,979 companies (3,466 + 2,987 + 2,526). The same window as a single query would have returned 5,000 — silently missing 3,979 companies.

If a single day ever does hit the 5,000 cap, that day is listed under truncatedDays in the run summary with a note telling you to narrow it by SIC code, type or location. It is never hidden.

The CSV the source serves is malformed — this handles it

Companies House serves this data as CSV with three unquoted variable-width fields. Measured on one real day of 3,466 companies:

• 35% of rows are wider than the 11-column header, because nature_of_business is rendered as a bare bracketed list — [85590, 85600, 88990, 94990] — which splits across CSV columns
• 246 rows carry commas inside the registered office address
• 8 rows have a comma in the company name — "CALEDONIAN WEDDINGS, TOURS & TRANSFERS LTD"

Read naively, a third of every lead list gets a SIC-code fragment where the address should be, and the comma-named companies end up with half their name filed as the company number. Neither throws an error; both just produce a list that looks fine and is wrong.

This Actor anchors on the company number and reassembles all three fields, and every release is checked against a captured real day before it ships.

Pricing

Pay per event: $0.0003 per company returned, and no run-start fee.

• One day of UK incorporations (~3,400 companies): about $1.00
• A full month (~70,000 companies): about $21
• Filtered to one industry, a month is usually a few hundred rows — cents

Companies excluded by your filters are never delivered and never charged, and a run that finds nothing costs nothing.
