Why us

Our foundation for every automation.

01

self-hosted n8n

Open source, on your infrastructure or sovereign cloud. No third-party platform sees your data. Workflows are yours, credentials stay with you.

02

Versioned like code

Workflows exported as JSON, tracked in your Git, reviewed in pull requests. A business change leaves a trace. No production drift without knowing who changed what.

03

Monitored in production

Monitoring, automatic retries, queues, alerts, and human validation for exceptions. A critical workflow is managed like a system component.

Automation stack

What we integrate.

n8n at the core, open-source components around it, and documented architecture for your IT teams to take over.

Client case

Imalize — from email orders to ERP.

Orders arrived via email, as attachments or in the body, in formats that varied from client to client. AI extraction, business validations, and purchase order creation in the ERP. Self-hosted n8n, with human oversight for edge cases.

Automation method

A project in five steps

A dedicated team from scoping to delivery with a dedicated project manager

01Scope

The existing, measured.

Inventory of repetitive tasks, measurement of actual time spent, identification of breaking points. No blind automation.

02Prioritize

ROI vs complexity.

We prioritize workflows that repeat, cost time, and can be made reliable. What still heavily depends on a human remains out of scope.

03Prototype

A workflow, in isolation.

Building a first workflow in a test environment, using real scenarios, alongside the current process.

04Industrialize

Self-hosting & monitoring.

Self-hosted deployment, monitoring, logging, automatic retries, human validation for exceptions, Git versioning.

05Maintain

Gradual handover.

On-call support if critical, quarterly workflow reviews, continuous training for your teams. Gradual handover if desired.

Sovereignty

Why self-hosted, by default.

Make and Zapier see all your data. For internal processes—invoicing, clients, HR, files—this is rarely acceptable. Self-hosted n8n solves the problem at its root.

Sovereign hosting

Scaleway, OVH, self-hosted, internal Kubernetes. Your data and credentials stay with you.

Open source

n8n, PostgreSQL, Prometheus, Grafana: no proprietary platform sees your data flow.

GDPR & compliance

Documented data flow, encrypted credentials, auditable logging. HDS-compatible for healthcare.

Reversibility

Workflows exported as JSON, in your Git. Your teams can take over without us.

FAQ

Frequently asked questions

The most common questions we get during scoping. If yours isn’t here, reach out!

Yes. We audit your existing setup, identify what needs migrating and what can stay, and rebuild critical workflows on self-hosted n8n. Migration is gradual, in batches—no big bang. Your data and accounts remain yours, giving you full autonomy.

Rule of thumb: if a task takes 10 minutes and repeats 50 times a week, it’s worth automating. But ROI isn’t just about time saved—reliability, traceability, processing speed, and scalability matter just as much. We quantify both dimensions during scoping.
