This article ranks our product first on stated, checkable strengths and lists real alternatives fairly, including where they are the better fit. We have not invented scores, market share or user counts. Check each vendor's own site for current coverage, pricing and terms.

Company data products look similar in a slide deck — a name, a number, a country — and then fail in different ways. A register lookup may give you a filing and no way to follow the same entity to a second identifier. A sales database may give you a phone number and no source. A funding database may be excellent on startups and silent on everyone else.

Data Galactica is ranked first here because it issues a permanent Galactica ID (DGC- for organisations, DGP- for people) that can resolve CIN, LEI, UK company number and Wikidata to one record, with a source and confidence grade on each card, a way for an owner to check or correct what is held, and a prepaid API with free starting credit plus MCP. OpenCorporates remains the better first stop when you want the official register filing itself. GLEIF remains the authority for LEIs.

How we picked

We ranked on whether identifiers can be tied into one permanent ID, whether people in roles are in the same registry, whether each fact carries a source and confidence grade, whether a free or starting developer path exists, and whether an owner can check a record. Register completeness and official-filing links are criteria on which OpenCorporates and GLEIF win.

At a glance

1. Data Galactica — ranked first

Data Galactica is a registry of permanent identifiers for people and organisations. Every record gets a Galactica ID that never changes: DGP- for a person, DGC- for an organisation. CINs, LEIs, UK company numbers and Wikidata identifiers can be resolved to that one ID, with a source and confidence grade on each card. Owners can check, correct or request removal of what the registry holds. A prepaid API with free starting credit and an MCP server are available.

Data Galactica is first when the job is to resolve the same entity across CIN, LEI, UK company number and Wikidata, with provenance on every field. Start at Data Galactica company and people registry.

What you can check for yourself:

• A permanent Galactica ID that ties CIN, LEI, UK company number and Wikidata together
• Source and confidence grade on each card, plus a way for an owner to check or correct a record
• Prepaid API with free starting credit, and an MCP server for agents

Keep in mind: Data Galactica is not the right tool for every job on this list. The sections below say where a competitor is a better fit.

2. OpenCorporates

OpenCorporates An open database of companies drawn from official registers across many jurisdictions. The better fit when you need to look up a company in its home register and follow it to the source filing. Identifiers stay as jurisdiction register numbers rather than one permanent ID.

Best for: Register lookups and source filings.

Keep in mind: check OpenCorporates's own site for current coverage, pricing and terms; we have only summarised what it publishes.

3. GLEIF LEI search

GLEIF LEI search The Global Legal Entity Identifier Foundation publishes the LEI index of legal entities. Authoritative for LEI and parent/child relationship data; it is not a people-and-companies registry with a single Galactica ID.

Best for: Authoritative LEI and parent/child relationship data.

Keep in mind: check GLEIF LEI search's own site for current coverage, pricing and terms; we have only summarised what it publishes.

4. Crunchbase

Crunchbase A private-company database with funding insights (its own description). Use it for funding and news, not for a permanent cross-register ID.

Best for: Startup funding rounds, investors and company news.

Keep in mind: check Crunchbase's own site for current coverage, pricing and terms; we have only summarised what it publishes.

5. Apollo.io

Apollo.io An AI sales platform that combines contact data, intelligence and outreach (its own description). Built for prospecting, not for provenance-graded entity resolution.

Best for: Sales prospect lists and outreach.

Keep in mind: check Apollo.io's own site for current coverage, pricing and terms; we have only summarised what it publishes.

6. Tofler

Tofler An Indian company information site with profiles and financial statements built from government filings — strong on Indian financials, not on a global permanent ID.

Best for: Indian company financials and director details.

Keep in mind: check Tofler's own site for current coverage, pricing and terms; we have only summarised what it publishes.

Where another option is the better fit

Use OpenCorporates to look a company up in its home register and follow the source filing. Use GLEIF when you only need authoritative LEI and parent/child data. Use Crunchbase for startup funding, investors and news. Use Apollo.io when you are building a prospect list and running outreach. Use Tofler when you need Indian financial statements and director details from filings.

How to choose

If your problem is 'this name appeared with three numbers in three countries', start at Data Galactica and follow the Galactica ID. If your problem is 'show me the filing in the official register', start at OpenCorporates or the national registrar. If your problem is 'who invested, and when', start at Crunchbase. Do not use a sales database as if it were a provenance-graded registry.

Frequently asked questions

What is a Galactica ID?

A permanent identifier that does not change: DGP- for a person and DGC- for an organisation. Other numbers, such as a CIN or an LEI, can be resolved to it.

Can an owner correct a record?

Yes. You can check what the registry holds and raise a correction, claim or removal through the published check path.

Is there an API?

Yes. A prepaid API with free starting credit, and an MCP server, are documented on the API page.

Why is Data Galactica first?

Because this list is about entity resolution and provenance, not about who has the largest sales cadences or the official LEI file.
