How this evidence set is built

Every published relationship on this site carries seven fields: source, source URLs, source date, date basis, match method, confidence and publication state. Where a field is missing it stays missing rather than being filled in.

Record layers

What is resolved, and how

01

Companies

466 canonical company records after alias resolution. 369 sit in the Series B or later-stage focus; the remainder stay visible as earlier-stage, acquired, historical or unconfirmed records.

02

Funding

733 public round records preserve reported stage, date, currency, amount and source URL. No FX conversion is used for ranking.

03

Investors

2243 company-investor relationships resolve to 1310 canonical investors. Lead, participant, lender, grant and accelerator roles remain distinct where the source supports them.

04

People

Only verified or listed public profiles from London People are included. News-target rows are excluded. The site publishes no emails, phones, officer rows, PSC/controller rows or home addresses.

05

Review

90 company records retain a review flag. “Verified” refers to identity matching or a published profile—not investment quality or current operating performance.

06

Public contracts

57 Contracts Finder award notices match 20 directory companies by Companies House number. Notice values are evidence of procurement, not recognised supplier revenue.

07

Regional context

12 ONS regions carry current Jobseeker’s Allowance claimant context; 10 also carry 2021 England and Wales Census workforce measures. These figures describe places, not company performance.

08

Registry context

376 company records match the Companies House projection by exact company number. Status, filing dates and official SIC codes are shown without addresses, officers or controller data.

09

Legal entities

52 GLEIF records match by exact Companies House number. LEIs are identifiers, not credit or investment-quality ratings.

10

Indexing quality

Investor pages need an official portfolio, at least three linked companies or two distinct relationship sources before entering the sitemap. Thin research records carry noindex.

11

Daily updates

The scheduled run refreshes configured Cloudflare layers, rebuilds and validates the site every day, and publishes only when the evidence fingerprint changes. See freshness status.

12

Limits

This is a dated public-source research snapshot. It is not a cap table, registry substitute, valuation service, complete global portfolio, solicitation or investment recommendation.

13

Object ownership

UKCI owns growth-company, funding and investor discovery. CompanyBeacon owns statutory entity, filing, supplier, charity and control master objects. See the boundary report.

14

Company changes

129 records overlap CompanyBeacon by exact company number; 2 have a retained status-change observation. UKCI links to the statutory timeline instead of duplicating it.

15

Charities & social enterprise

0 exact Charity Commission company-number links are present. Charity status is never treated as a social-enterprise classification; no dedicated social-enterprise source means no claim.

Sources and licences

Every layer, named

Public-register layers are matched on exact identifiers, never on fuzzy company names. Companies House, Contracts Finder, ONS/Nomis and Charity Commission material is used under the Open Government Licence v3.0; GLEIF legal-entity data is published under CC0 1.0. Official registers remain authoritative: follow the named link on any record page for the current official position.

Publication thresholds

What is held back

A funding round gets its own page only when it has a resolved company, a disclosure date, a stage and at least one retained source URL: 730 of 733 records qualify. An investor page enters the sitemap only with an official portfolio URL, three or more linked companies, or two distinct relationship-source URLs: 1066 of 1310 qualify, and the remaining 244 stay navigable under noindex. Sector, location and official-SIC pages need at least three companies; public-buyer pages need at least two matched notices.

Limits

What this is not

This is a dated public-source research snapshot. It is not a cap table, a registry substitute, a valuation service, a complete global portfolio, a solicitation or an investment recommendation. “Verified” refers to identity matching or a published profile, never to investment quality or current trading performance. A retained investor relationship is not proof of a current holding. Contract notice values are procurement records, not recognised supplier revenue. Regional indicators describe places, not the companies headquartered in them.
