Our n8n agency, based in Paris, automates business processes for small and mid-sized companies: custom workflows, AI agents, tool integration and migration from Zapier or Make. On n8n Cloud or self-hosted, with a trained team that stays in control.
Three quick steps to prepare a useful conversation.
Step 1/3
They trusted PeakLab to automate their processes
We map your processes, tools and volumes, then estimate the hours saved each week per workflow. You leave with a prioritised roadmap, a reasoned architecture choice and an ROI estimate.
A turnkey offer: technical scoping, development, testing and go-live of your workflows and AI agents on n8n Cloud or self-hosted, with error handling, monitoring and documentation. Support continues as new needs arise.
An n8n expert joins your team to take over existing workflows, migrate from Zapier or Make and train your staff. The n8n training is tailored: your own processes serve as exercises.
Tools, connectors and use cases
For Solteo, a solar panel installer, PeakLab audited the administrative processes, then automated the paperwork: automatic document generation, file tracking, follow-ups and exchanges with external platforms.
According to the published case study, administrative workload fell by 60%, the team handles 2.5 times more projects in parallel and revenue grew by 38%.
This project runs on a custom platform, not on n8n. The method is the same: map the process, automate the core, keep control of the exceptions that are not automated.

Simultaneous missions
Six areas of expertise from a team skilled in both n8n and software development, from audit to maintenance, without creating a new point of failure.
We observe the real process: trigger, steps, tools, data, exceptions and owner. The audit measures time spent and expected gains, then ranks automations by strategic impact. If the need goes beyond automation, our digital transformation agency scopes the project.
Sales prospecting, customer support, invoicing, onboarding, logistics, SEO reporting, order status in Xano: we build tailored workflows, split into sub-workflows, with named and commented nodes. Your team understands what runs and can evolve it.
CRM (HubSpot, Pipedrive, Salesforce), ERP (Odoo, SAP), Airtable, Notion, Slack and no-code apps such as Webflow, Bubble or Xano: n8n connects to your information system through native integrations, APIs or webhooks. For an internal API or specific logic, we can build a custom node.
n8n orchestrates Claude, GPT or Mistral to classify an email, extract data from an invoice, qualify a lead or answer a customer from your knowledge base. Each agent has limited permissions, controlled outputs and human approval on sensitive cases.
The n8n Cloud offer removes any infrastructure to manage. A self-hosted n8n, on a server in France or in Europe, keeps your data in-house and handles large volumes. We install, secure, back up and update the instance, with a test environment separate from production to keep it stable.
Error handling, automatic retries, Slack or email alerts, execution logs: a production workflow must report what breaks. We also handle maintenance and migrate your Zapier or Make scenarios to n8n, one by one, without interrupting the business.
Cloud or self-hosted instance, workflows, credentials and data stay in your name. Everything exports as JSON: full flexibility to change provider without starting over.
Every workflow includes retries, alerts and manual recovery to keep operations running. An unavailable API never makes an order or a lead disappear.
Your staff learn to read, edit and build n8n workflows, with written documentation for every automation and every connected system, so you stay autonomous.
If Zapier, Make, a native feature or custom code serves your need better, we tell you before building anything.

“We're going to talk about AI, development, digitalization, but I think we shouldn't forget the human aspect and that's what I found with PeakLab. This proximity, this human support. I needed advice, not just an executor.”
Victor
CEO at ODD Pharma
“Great collaboration experience. Lucien demonstrated excellent technical skills, organization and listening. The project progressed efficiently under great conditions with smooth communication. Reliable, involved and full of initiative. I recommend.”
Janine

An n8n automation agency designs, deploys and maintains automations on n8n, a workflow platform with publicly available source code. It works for SMEs, firms and companies that want to gain efficiency without piling up software, and refocus their teams on strategic work.
n8n connects your tools (CRM, ERP, messaging apps, databases, spreadsheets) through APIs and webhooks. It then runs repetitive tasks for you: data entry, follow-ups, automatic sync, month-end reporting.
Each workflow chains nodes: a trigger, actions, conditions. The visual editor is easy to learn, and a node accepts custom JavaScript or Python code when the logic gets advanced. That is n8n's edge over Zapier or Make: flexibility on demanding processes.
n8n runs on n8n Cloud, the official hosted service, or self-hosted on your own server. A self-hosted n8n keeps your data on your infrastructure, in France or in Europe. In return, someone has to handle updates, backups and security.
With LLMs, n8n also orchestrates AI agents. A model such as Claude or GPT reads a request, picks an action, queries your data and prepares an answer.
A useful AI agent stays within limits: narrow scope, execution logs, human approval on sensitive decisions.
An automation agency does not sell workflows by the piece. It starts from the process, measures the hours lost, then automates what pays off over the long term, with a tailored approach that fits your maturity.
PeakLab adds custom development and business applications when n8n is no longer enough. Signs it is time to call in an automation agency:
Because sooner or later a workflow hits a missing API, logic that is too complex or a volume that is too heavy. At PeakLab, n8n experts and developers work in the same team: we write the missing connector or move the logic into code. For conversational assistants, our chatbot agency takes over.

It analyses your processes, designs the workflows, connects your tools through APIs, adds AI where useful, then handles deployment and maintenance of the automations. It helps you choose between n8n Cloud and a self-hosted instance, provides a clear quote and trains your team so it stays autonomous.
n8n is a workflow automation platform. It links your applications through visual nodes (over 400 integrations, plus an HTTP node for any API) and accepts JavaScript or Python code. It runs in the cloud or on your own server.
Zapier is the simplest for a few light automations. Make suits visual scenarios of medium complexity. n8n wins on high volumes, complex logic, code and self-hosting. For three simple automations, we will tell you to stay on Make or Zapier.
n8n's code is public under the Sustainable Use License, a so-called fair-code licence. The self-hosted version is free for internal use: you pay for the server, not the tool. n8n Cloud and enterprise plans are paid.
n8n Cloud fits if you want to start without infrastructure. Self-hosting is the way to go for sensitive data, high volumes or integration with your internal network. It requires serious operations: updates, backups, monitoring. We decide during the audit.
The budget depends on the number of workflows, the tools to connect, data complexity, the share of AI and the level of maintenance. We separate audit, build and support in a written proposal, after a first call.
It depends on the number of tools, API quality and the approvals required. We first deliver a pilot workflow on the priority process, then expand. The timeline is set out in the written proposal.
Those that repeat often, follow stable rules and keep several people busy: sales follow-ups, marketing lead qualification, logistics tracking, support request triage. The audit ranks them by gain and risk.
Yes. n8n handles high volumes in queue mode, with multiple workers, SSO and permission management in enterprise plans. For a large organisation, we scope architecture, governance and security with your IT department.
Yes. n8n includes AI agent nodes connected to Claude, OpenAI or Mistral, with memory and tools. An agent can read an email, look up an order, update the CRM and draft a reply. We add guardrails and human approval on sensitive actions.
Not for most things: the editor is visual. Code becomes useful to transform complex data or call a specific API. We train your team to edit everyday workflows.
Yes. We inventory your zaps and scenarios, migrate the most useful ones to n8n one by one and test them before switching off the old tool. The business keeps running during the migration.
Minimal permissions per integration, encrypted secrets, separate test and production environments, tracked updates and tested backups. When self-hosted, the instance stays on your server.
Yes. We train your staff to read, edit and build workflows, with exercises on your own processes and documentation to keep at hand.
Your team, us, or both. Maintenance covers monitoring, n8n updates, incident fixes and new automations.
Yes. Our head office is in Paris, at 60 rue François Ier, and we support companies across France and abroad remotely, by video call and in your shared tools.
