Evidence and verification infrastructure for North African markets
Evidence infrastructure for markets where data cannot be taken for granted
Traceable numbers. Reproducible checks. We read the official PDFs, reconcile them to their own printed totals and keep, for every row, the address and SHA-256 fingerprint of the source document. A fingerprint proves which document a row came from, not that every extracted value is correct: our checks and their known limits are published on the data-status page.
Mission
To make evidence accessible in markets where data quality is contested: every published figure should be traceable to the official document it came from, and every check repeatable by anyone. We also publish what our checks do not yet cover.
Vision
Transparency as public infrastructure, and a demonstration that rigorous data and AI governance can work where information is hardest to establish: image-only documents, late filings, undeclared corrections.
The problem we take off our partners’ desks
On the Casablanca Stock Exchange, as on many emerging markets, official information exists but arrives as PDFs, sometimes with no text layer, no history and no record of changes. An analysis team spends weeks on it; a reading error becomes a decision error. We do that work once, verifiably, for everyone.
How we work
- CollectThe official document is archived as served, addressed by its SHA-256, with its publication headers.
- VerifyAutomated checks reconcile every table to its own totals. A reconciled total does not validate every value; the independent audit of 29 October 2026 found that admission does not yet enforce every published check, and the fix is in progress.
- ReceiptEvery row keeps the address and fingerprint of the PDF it came from; evidence tables refuse updates and deletes from clients and from the application.
- ComputeLiquidity, sector rotation, technical statistics and links with global markets, each with its sample size and margin of error.
- PublishPublic pages, APIs and reports; disputes and corrections are public too.
The evidence, right now
These figures are read from our own tables as this page is built, not typed by hand. Each one links to the page that documents it, with its limits.
Our evidence standard
- Every published row links to the official document it was extracted from and to its SHA-256 fingerprint. The fingerprint identifies the document; on its own it does not prove the extracted value.
- Failed checks are published: an unverified session shows as such, never as data.
- Evidence tables are append-only: a value is never rewritten, a revision is a new row.
- A public notary (RFC 6962 Merkle roots, OpenTimestamps calendar receipts) lets anyone show that a committed document has changed. Its current coverage is partial and published on the data-status page.
- Statistics are published with their population and dates, sample size, confidence interval and false-discovery-rate control; an association is never presented as a cause.
- Natural persons are never named, at any access tier.
- We use only external data whose licence is documented, and we exclude proprietary vendor indices. For Casablanca Stock Exchange data, a written position on our uses has been requested.
What we offer
Each offering is described by what is delivered and how it is governed.

- Governed by
- Every number in the prose is compared automatically with a receipted fact sheet. Before any publication, a human review bound to the exact text will be required; this control is being built.
Research partnerships
- Delivered
- Reproducible datasets for universities: market microstructure, information quality, issuer governance.
- Governed by
- Frozen versions, published fingerprints and a documented method so every result can be replicated. A qualified research dataset (rights, history, dataset card) is in preparation and not yet released.
Newsroom access
- Delivered
- The full shareholding register, histories and exports for journalists.
- Governed by
- Free with verified credentials. Statistical screens are never allegations; issuers have a right of reply.
Oversight and NGO programmes
- Delivered
- Transparency indicators: publication delays, machine-readability of filings, declared and undeclared corrections.
- Governed by
- Proof required for every dispute, a public status for every case, a public corrections ledger.
Accessibility packs for foreign investors and index providers
- Delivered
- Liquidity by segment, off-book share of trading, shareholding concentration, currency conversion of indices.

Who we work with
We are looking for partners who need reliable data on emerging markets and share our standard of evidence.
Financial institutions
Asset managers, banks, funds and index providers: ready-to-use data, custom databases, accessibility packs.
Non-profit organisations
Transparency and good-governance organisations: public indicators, monitoring data, joint programmes.
Universities
Research groups and scholars: reproducible data, methodological collaboration, supervised projects.
Journalists
Newsrooms and independent journalists: free verified access, citable evidence, protected sources.
Authorities and oversight bodies
Information-quality indicators and reconciled registers, shared within an agreed framework.
What we do not do
- No investment advice: we publish facts and descriptive statistics, never recommendations to buy or sell.
- A statistical screen is never a public allegation; nothing naming an issuer is published without its right of reply.
- Sources and whistleblowers are protected: no IP address kept, pseudonymity available, identity never published.
- We do not sell the exchange’s raw values; their redistribution is subject to its terms, and a written position on our uses has been requested. Our other sources are public or open-licence.
- No price, client or partner is announced here until it exists.
