As-reported company
financials, point-in-time.

plaingraph turns statutory filings into clean, point-in-time company financials. Balance sheet and P&L, funding events and implied valuations, charges and group structure — for UK companies (Companies House), Estonian companies (e-Business Register), and EU/UK-listed issuers (ESEF and the FCA National Storage Mechanism) — joined across registers by GLEIF LEI. Screen the whole register by as-reported financials or recent funding, drill into any company, and watch the ones that matter. Every value links back to the filing it came from.

Every numeric field carries a coverage flag (ixbrl / pdf_heuristic / unavailable); implied valuations are filing-derived estimates that carry a confidence band and the source filing date. plaingraph surfaces evidence — you make the decision.

MCP server + plain REST API — connect ours, or build your own MCP on it.

Built for people who track companies

Private-market investors

Follow SH01 funding events and filing-derived implied valuations, read UK private-company accounts, and see point-in-time history — the raw material for angel, micro-VC and corp-dev tracking.

Finance & credit teams

Monitor the companies you depend on: registered charges, insolvency events, late filings, and balance-sheet movement over time. Company financial monitoring — evidence, with its source, not a score.

Journalists & researchers

Every figure links to the filing it came from, entities join across registers by LEI, and the sources are all public-domain or CC-BY — provenance you can cite.

Company intelligence & financials

Balance sheet, P&L, cash flow, runway, headcount — and the latest implied valuation. UK accounts from iXBRL and PDF, Estonian annual reports, as-reported IFRS fundamentals for EU/UK-listed issuers (ESEF), and UKSEF structured accounts for listed UK PLCs (FCA NSM).

Group structure & ownership (GLEIF)

Unify the same company across registers by GLEIF LEI, then surface accounting-consolidation context: walk corporate parent and subsidiary relationships — from a subsidiary's accounts up to the parent that consolidates them. Company-to-company group structure, not a people graph.

Screen the whole register

Ask across every company at once: total assets over a threshold, negative equity, a sector band, or a capital raise in a window — typed filters over as-reported figures, one row per company, ready to drill into or watch. Cross-company screens over REST and MCP, priced one unit per page.

Watch & notify

Subscribe to meaningful changes — accounts filed, priced rounds, charges, status and name changes, insolvency cases. Email digests, HMAC-signed webhooks, or MCP poll, with replayable history.

Provenance & coverage flags

Every value links to its source record. Every parsed numeric carries a coverage flag, so an agent can't silently treat a missing field as a clean read.

One provenance-first graph across registers and group structure — compose financials, charges, valuation and consolidation context in a single call.

For developers and agents

The same as-reported data over a plain REST API and a hosted MCP server — the endpoints are identical, so you can connect ours or build your own MCP on them. Schemas are explicit and agent-composable, every numeric carries its coverage flag, and you can subscribe to changes with HMAC-signed webhooks.

API + MCP access comes with every plan — tiers differ by read model, not channel. Cross-company screens (screen_companies, screen_events) cost one unit per page of up to 100 companies. See the Developer plan.

FAQ

What is plaingraph?

plaingraph is as-reported company financial data from statutory filings — point-in-time financials, funding events, implied valuations, charges and group structure for UK, Estonian and EU/UK-listed companies, joined across registers by GLEIF LEI. Track a set of companies and get alerts, or build on the same data over a hosted MCP server and a plain REST API.

How do AI agents access plaingraph?

Through a hosted MCP (Model Context Protocol) server so agents can call it directly, or over a plain REST API. The same endpoints power both — you can build your own MCP on them if you prefer.

Which sources do you cover?

UK Companies House (registry, filings, charges, accounts — a live change feed), the Estonian e-Business Register (registry and annual-report financials — a snapshot), ESEF (as-reported IFRS fundamentals for ~5,000 EU/UK-listed issuers — batch-built), and the FCA National Storage Mechanism (UKSEF structured accounts for listed UK PLCs — on demand). All joined to a global spine through GLEIF (~2.5M LEIs). See the coverage page for licences and caveats.

What financial data is available?

Balance sheet (equity, total assets, current assets, cash, liabilities), profit & loss (turnover, gross / operating / net profit), cash flow, employee count, director remuneration, share capital, plus a derived implied valuation from the most recent priced share allotment. UK companies come from iXBRL and e-filed PDF accounts; Estonian companies from filed annual reports; EU/UK-listed issuers from as-reported IFRS filings (ESEF) and UKSEF structured annual reports (FCA NSM). Outstanding charges, group structure (GLEIF accounting consolidation) and governance signals are surfaced as separate tools.

Can I screen companies by financials or funding activity?

Yes. Cross-company screens run over the same API and MCP server: filter every company at once by as-reported figures (total assets, turnover, net assets — including negative equity, cash, headcount), registry facts (status, SIC sector, incorporation date), or capital activity (share allotments and priced rounds in a date window). Results come one row per company with provenance, ready to drill into with the per-company tools or add to a watchlist. Screens are neutral filters over as-reported filings — no scores or rankings — and each page of up to 100 companies costs one metered unit. Funding-event coverage accrues forward from our live-feed start date; every response states its coverage honestly.

How does Watch & Notify work?

Subscribe to a company and an event-type list — accounts filed, share allotment, charge created or satisfied, status or name change, insolvency case. Get an email digest, HMAC-signed webhooks, or poll via the MCP watch_events tool. Subscribe is idempotent; the event log is replayable.

Which companies have the best financial coverage?

UK companies filing iXBRL accounts (currently ~40% of filings; mandatory from 2027) have the richest data — full balance sheet plus P&L. Those filing e-PDF accounts get balance sheet basics via heuristic extraction. FRS-105 micro-entities file no P&L by law. Listed UK PLCs whose Companies House copy is PDF-only are served from their UKSEF structured filing at the FCA NSM. Estonian companies file structured annual reports. Every numeric field carries a coverage flag (ixbrl / pdf_heuristic / unavailable) so the source is always visible.

How much does it cost?

One honest meter: the companies you track. Prosumer is €19/mo for up to 50 tracked companies, Power is €49/mo for 250, and a metered Developer plan serves agents and applications. Search, company profiles and coverage look-ups are free on every plan; API and MCP access come with every tier. See pricing.

Is there a free tier?

There's no permanent free tier, but every plan starts with a 14-day trial (a card is required, and you can cancel anytime). Discovery reads — search, company profiles, and coverage look-ups — are free on every plan.

Does plaingraph include people data?

No. plaingraph is a company-data product — not a people-search or compliance-screening (KYC/AML/sanctions) tool. It does not ingest officer, PSC / beneficial-owner or sanctions datasets; incidental personal data in public filings is handled as described in the privacy policy.
