About us
Enterprise-grade data engineering, delivered at a human scale
CoHub — trading as YesuNesan Co Hub Ltd — is an independent consultancy based in the United Kingdom. We work with organisations that have outgrown spreadsheets and ad-hoc scripts but don't want the cost, pace or politics of a large systems integrator.
Our roots are in building software that brings people together: platforms for community organisations, local enterprises and purpose-driven startups. That same principle shapes how we do data work — technology should make collaboration easier, not concentrate knowledge in one team's heads.
Today we focus on the data and AI foundations that make everything else possible: reliable pipelines, well-modelled warehouses, clear definitions and reporting people actually trust. Every engagement is delivered hands-on by a senior practitioner and ends with your team holding the keys.

What we believe
Clarity before technology
The right tool is obvious once the question and the decision it supports are clear.
Build to be handed over
Tests, documentation and training are part of the work, not an optional extra.
Honest about AI
AI pays off on clean, governed data. We'll say so if the foundations aren't ready.
