Enterprise-grade from day one
Live from the first day, and portable later to any system. No vendor lock-in to Jourier: take the code, the schema and the models and run them yourself.
Accounting & Finance
Connect Lemonsoft
Dashboards, a full API and MCP access over your Lemonsoft data. Hosted in Finland. Self-hostable, or buy the platform outright and run it yourself.
Portable technical infrastructure to any cloud.
A production-ready foundation designed to scale. Plug in pre-built modules for common workflows, or build your own on top.
Hosted in Finland
Data and AI run in a Finnish data centre. UpCloud in Helsinki, and Mistral trained with CSC on the LUMI supercomputer in Kajaani.
Enterprise modular architecture
Scales to any level, from a new startup to a large enterprise. Build your own modules, or change the ones that ship.
The stack behind the unicorns
Talos Linux, Kubernetes and Cilium. GitOps deployments, a separate database per customer, automated security controls and self-healing.
The views ship with the product
Profit and loss, cash flow and cost-centre reporting are already built. Connect Lemonsoft and they fill with your numbers. There is no modelling project to sit through first.
Lemonsoft API
One API over Lemonsoft and everything else
Most systems expose one API shaped around their own storage. Useful, but you build against that shape, handle its pagination, and repeat the exercise for every other system you own.
Jourier reads Lemonsoft and serves the result as modelled JSON, on one endpoint, alongside every other system you connect. It is joined, typed and reconciled to what the dashboards show.
- Invoices, ledger, cost centres and dimensions as first-class objects
- The same numbers the dashboards use, from one definition
- Read-only against Lemonsoft; nothing is written back
# every cost centre, this month, joined to budget GET /v1/finance/cost_centres?period=2026-08 { "source": "lemonsoft", "as_of": "2026-08-16T06:12:00Z", "rows": [ { "code": "200", "actual": 184320, "budget": 175000, "var_pct": 5.3 } ] }
Lemonsoft MCP
Ask Claude about your own ledger
Model Context Protocol is how an AI assistant calls a real tool instead of guessing. Jourier exposes your connected systems as MCP tools, so Claude, Cursor or any MCP client can query Lemonsoft data directly, and answer from the ledger rather than from a plausible sentence about it.
Every answer resolves to rows you can open. The model retrieves; it does not compute the number, which is the only reason the answer is worth having.
- Works with Claude Desktop, Cursor, and any MCP-compatible client
- Scoped to what that user is allowed to see
- Self-hosted models available, so your ledger never leaves the EU
You Which cost centres are over budget this month, and by how much? Claude Two are over: Sales by 5.3% and R&D by 2.1%. Both driven by contractor lines.
Where the data lands
Lemonsoft data in the tool you already use
Each has its own setup page: what syncs, how often, and what the schema looks like on arrival.
Lemonsoft is one door in
Behind it is a full platform. EU-hosted in Finland, built on open components, portable by construction. None of it depends on staying a Jourier customer.
Sovereignty
Finnish hosting, Finnish AI
Your data stays in Finland, on EU infrastructure, under EU law. The AI that reads it is self-hosted, so your ledger is never a US vendor's training material.
The platform ArchitectureSelf-hostable Kubernetes
Standard Kubernetes, open components. Take the manifests and run it on your own cluster whenever you decide to. No proprietary runtime holding you in.
The platform AtlasCompany intelligence
Every registered Finnish company: financials, ownership, lifecycle and public procurement. Find buyers who look like your best customers, and tenders you can bid on.
Company Atlas MonitoringWatch what moves outside
Continuous external monitoring on independent scopes: supply chain, competitors, and how visible you are to AI assistants. It tells you; you don't go looking.

Lemonsoft and Jourier, answered
Can I get Lemonsoft data into a dashboard?
Yes. Jourier reads Lemonsoft and serves profit and loss, cash flow and cost-centre reporting as dashboards that are already built. You connect Lemonsoft and they fill with your numbers, so there is no modelling project first.
Does Jourier write anything back to Lemonsoft?
No. The connection is read-only against Lemonsoft. Nothing is written back.
Where is Lemonsoft data stored when I use Jourier?
In Finland, on EU infrastructure, under EU law. The AI that reads it is self-hosted, so your data is never a US vendor’s training material.
How long does connecting Lemonsoft take?
The connector is live. Connecting is a matter of pasting credentials: nothing is installed and no port is opened, and data flows the same day.
Can I use Lemonsoft data from Claude or another AI tool?
Yes. Jourier exposes MCP tools, so Claude, Cursor or any MCP client can query Lemonsoft data directly and answer from the ledger rather than from a plausible sentence about it. Access is scoped to what that user is allowed to see.
Can I run it on my own infrastructure?
Yes. It is standard Kubernetes built on open components. You can take the manifests and run it on your own cluster whenever you decide to, and there is no proprietary runtime holding you in.
Does this work with other systems as well as Lemonsoft?
Yes. Jourier serves Lemonsoft alongside every other system you connect, on one endpoint, joined, typed and reconciled to what the dashboards show.
