Jourier builds the Data Hub on top of PostgreSQL (your existing environment, or a new one). Operational systems flow in via real-time CDC and webhooks. Modeled tables in PostgreSQL become the layer that BI tools, AI agents, MCP servers, and bespoke applications all read from.

PostgreSQL is a open-source relational database. Jourier brings the modeling, the pipelines, and the consumption layers, on top of PostgreSQL's engine.

Pick PostgreSQL when your customer cloud already hosts it, when the workload pattern fits PostgreSQL's strengths, or when your team has the PostgreSQL skills in-house. Jourier doesn't sell PostgreSQL licences — your contract stays with PostgreSQL Global Development Group. We bring the engineering and the modeling on top.

Can Jourier work with my existing PostgreSQL environment?

Yes. Jourier builds the Data Hub on top of your existing PostgreSQL setup: same workspace, same compute, same governance. Source pipelines, modeled tables, and consumption layers all live inside PostgreSQL unless you ask otherwise.

Does Jourier require PostgreSQL?

No. Jourier supports PostgreSQL as one of several backends. If your stack already runs on Snowflake, Databricks, Microsoft Fabric, BigQuery, Postgres, or Supabase, the Data Hub adapts to it. PostgreSQL is the right call when your customer cloud already hosts it or when the workload pattern fits PostgreSQL's strengths.

How does the Data Hub differ from off-the-shelf PostgreSQL content?

Off-the-shelf PostgreSQL content is generic. Jourier's Data Hub is bespoke, modeled to your operations, joined across the systems your business actually runs. Same PostgreSQL engine underneath, but a layer designed for your business, not someone else's.

Who owns the PostgreSQL notebooks, schemas, and configuration?

You do. Jourier delivers everything as code in your PostgreSQL workspace, with documentation. Hand it to another vendor or take it over yourself whenever you want. No lock-in, no per-engagement licence.

Can I switch warehouses later?

Yes. The Data Hub model is portable. Most of the SQL ports between PostgreSQL and another warehouse with light editing; ingestion pipelines can re-target. Migrations of this kind are also part of what Jourier does.

What does a Jourier engagement on PostgreSQL cost?

Bespoke project, scoped to the data that matters. PostgreSQL compute is paid directly to PostgreSQL's vendor (Jourier doesn't add a markup). Jourier's fee is project-based, not subscription-based. No platform fees if you self-host the orchestration.
