An operating system for knowledge organisations
An integrated working environment for knowledge-based organisations: documents, projects, communication, CRM, HR and payroll, live broadcasts, and networking and meeting tools in a single system. It was built because no off-the-shelf tool matched the way a think tank works.
01Situation
An analytical organisation works with more than a dozen tools at once: documents in one, projects in another, contacts in a third, broadcasts in a fourth. Every switch costs time, and knowledge is scattered across systems. NES needed a single environment that mirrors a think tank's work cycle, from the first note to the broadcast.
02Actions
6 steps in the order in which the project was built.
Communication and broadcasting, planning and coordination, relationship development, operations and organisational governance.
A block editor, a code editor, whiteboards, real-time co-editing (Yjs, CRDT), PDF preview and generation.
Video via LiveKit and the in-house NES-Connect WebRTC/SFU stack, RTMP/SRT broadcasts with simulcast and SVC.
Lovable Cloud (managed Supabase), PostgreSQL, Deno edge functions, Row-Level Security and full-text search.
TypeScript in strict mode, Vitest, Playwright, pgTAP and axe-core tests, append-only SQL migrations and release gates in GitHub Actions.
A free Starter plan, a Team plan and Enterprise deployments.

“A tool for a knowledge organisation should mirror its rhythm of work. I started Merydian by describing the NES processes and chose the technology to fit them afterwards; that is why the modules connect where the work connects.”
06Details
Modules are grouped by what the organisation does, not by the type of tool.
The design assumptions include encryption of chat columns (AES-256), an audit log chain based on SHA-256, row- and role-level access control (RLS, RBAC) and hosting in the EU. The Enterprise plan provides for SAML SSO and SCIM.

09FAQ
Merydian is an integrated working environment for knowledge organisations: more than 20 modules in four areas – communication and broadcasting, planning and coordination, relationships, and operations and governance. Igor Miasnikow designed and built it end to end for New European Strategies.
In the European Union (Frankfurt). The design includes row- and role-level access control (RLS, RBAC), AES-256 encryption of chat columns and a SHA-256 audit log chain; the Enterprise plan provides SAML SSO and SCIM.
Through the public meeting booking module at merydian.app/meetings/igor-miasnikow, which schedules a conversation with the board of New European Strategies.
