See the companies behind your companies.

bigECOs reads the entire UK register — who owns whom, when every subsidiary was born, who just raised — and turns it into your warmest way into any account, or your next acquisition thesis.

The live product on a sample group — assembling by incorporation date. Drag it, zoom it. (Illustrative data.)
For enterprise sales teams

The group, before the teaser.

Every target's true shape, read from filings — not from their deck:

How it works

Three steps from a customer list to a map of your market.

1

Bring your customers

CSV in minutes, or Salesforce on Enterprise. Your data stays private — it's the lens, never the product.

2

We map them against the register

bigECOs resolves every customer into the ownership graph — parents, siblings, subsidiaries, JVs — and keeps it fresh monthly.

3

Act on what appears

Warm paths, inside references, funded look-alikes, whole-group structures — and living maps you can publish to prove it.

Living maps

Your market, published.

Every ecosystem becomes an interactive map you can share with a link or embed on your own site — story chains that reveal a path step by step, a ⏱ timeline that plays the group's growth, a 🗺 map of its national footprint. Names only. Always yours to revoke.

Story chains — reveal the route, node by node Timeline — watch the group assemble by year 🗺 Geography — the footprint on a map of Britain & Ireland 🔗 Embeds — light or cinema, on any site
Provenance

Where every claim comes from.

No scraped guesses, no bought lists. Everything bigECOs shows you traces to a public filing — and your own data never leaves your account.

Companies House bulk dataThe full register — every live company, officer and filing history — refreshed monthly.
The PSC registerPersons and corporates with significant control: the spine of 685,000 ownership links.
iXBRL accountsShare-premium movements read from raw filings — equity raises surfaced before they're news.
Your CRM — privateLayered on top as your lens. Public shares carry company names only: never CRNs, never notes, never emails.
