A common language
between your data
and your users.

Koine is the governed middleware that sits between any database, any AI model, and any user asking a question. Analysts get answers in plain language. Integrations move data between systems. Every step is scoped, cited, and audited. Nothing passes without permission.

What Koine does

A pipe, not a warehouse.

Your records stay on your infrastructure. Koine reads them to compose an answer, or moves them from source to destination through governed tools — then the data goes where it was going. We keep the audit, not the rows.

For analysts + leadership

Ask in English, French, or Portuguese. Get answers with citations, the SQL that ran, and ContextFacts that flag caveats.

For operators + developers

Connect any database. Author tools. Map fields between systems. Schedule pipelines. Every write gated by dry-run + approval.

Three layers · one product

Connect. Compose. Answer.

Koine is structured so no layer can overreach. Governance runs once, at the middle, on every request — no matter where it entered from.
Layer 01

Connector

A single bidirectional interface to any database or SaaS. Postgres, MySQL, SQLite, SQL Server, REST, Sheets, ArcGIS. Read and write through the same contract.

Verticals

Products built on Koine.

Koine is the platform. Verticals are full products built on it — branded, specialised, with their own tools, prompts, and chat UI. Each one proves the platform; each one hardens the core.
Civil Registration · CRVS

VitalReg

A national CRVS intelligence platform. Birth, death, attestation, stillbirth — indicator calculators, data-gap detection, fuzzy duplicates, governed exports, NIN pipeline aware. In pilot with Nigeria's NPC.

Who Koine is for

Institutions that move in quarters, not sprints.

Koine is built for the inner ring first — African ministries, pan-African banks, multi-state NGOs. Expansion outward comes through proven verticals, not by chasing the global market before the continental one is defended.
Ministries & statistics offices

Civil registries, customs, taxation, health information systems. Governance first, audit second, AI third.

Multi-state NGOs & donors

UNICEF, GAVI, World Bank programmes. Governed exports across partners, with residency and PII handled for you.

Pan-African banks & telcos

Postgres-scale data, regional residency rules, central-bank reporting. Koine sits between core systems and analyst desks.

Consultancies & operators

License Koine, build your own vertical on top. White-labelled for your clients, maintained by you, supported by us.

The single sentence

Koine is the governance-first common tongue between any system and any user, so that the people who need to make decisions can stop waiting on the people who need to run queries.
