Senior-Led Execution with 42 Successful AI Deployments
- Senior-Led Execution with 42 Successful AI Deployments: Every architecture is designed and audited by senior experts who have delivered 42 distinct AI applications.
- Technical Sovereignty: We build on your infrastructure (Azure, AWS, or On-Prem) so you maintain 100% data ownership and no per-task fees.
- Capability Transfer: We don't just build and leave; every project includes team training and technical runbooks to ensure you aren't tethered to a vendor.
How do complex API integrations work with n8n?
Complex API integration means connecting systems that don’t speak the same language. This involves handling custom headers, OAuth2 authentication, and paginated data. It’s difficult because one small change in an API can break a business-critical process.
We handle the logic that basic connectors cannot. This includes “webhooks”—real-time triggers—and “ETL” (Extract, Transform, Load) processes that clean your data before it moves.
What we deliver:
Bidirectional sync between CRM, Finance, and Cloud tools
Custom JavaScript nodes for complex data mapping
Resilient error-handling paths to prevent data loss
What is included in AI tool implementation and training?
We implement AI tools that do more than chat. We build “RAG” (Retrieval-Augmented Generation) systems. This allows an AI to look at your private company files to answer questions accurately without “hallucinating” or making things up.
How your team learns:
Admin Training
How to manage and monitor AI agents.
Prompt Engineering
How to get the best results from the system.
Governance
Setting rules for who can access specific AI capabilities.
How do you ensure security, governance, and reliability?
Automation is a risk if not governed. We treat every n8n implementation with enterprise-grade security. We use “environment variables” to keep your passwords secret and “version control” so we can undo changes instantly if needed.
How we reduce risk:
Data Residency
Your data stays in New Zealand or your chosen cloud region.
Audit Logs
Every workflow execution is logged and searchable.
Encrypted Vaults
Secure storage for all API credentials.
What is the Lumen delivery process?
We follow a strict “Discovery to Support” framework. This ensures we never build the wrong thing. We start by mapping your manual steps and end by training your team on the new automated system.
Our milestones:
Discovery
Defining technical requirements and API limits.
Architecture
Designing the workflow diagram.
Build & Test
Developing in a sandbox environment.
Deploy & Train
Moving to production and conducting workshops.

What are the best use cases for n8n consultancy?
Most companies use n8n to bridge the gap between their “SaaS” apps (like Zoho or Xero) and their internal databases.
Examples by department:
Finance
Auto-matching bank feeds to invoices in Xero.
Operations
Syncing inventory across multiple e-commerce stores.
Marketing
Using AI to categorize and route incoming leads.
IT
Automating user onboarding across Azure and Slack.

FAQ
What is n8n?
n8n is a powerful automation tool that allows you to connect different software applications. Unlike Zapier, it can be hosted on your own servers, giving you more privacy and lower costs.
Do I need to host n8n myself?
You can use n8n Cloud, or we can set it up on your own Azure or AWS account. Self-hosting is usually preferred by our enterprise clients for better security and data control.
Is n8n better than Zapier or Make?
n8n is often better for complex tasks because it allows for custom code and has no “per-task” pricing. It is a professional tool for builders who need high flexibility and data ownership.
How long does an n8n implementation take?
Small integrations take 1–2 weeks. Complex AI implementations and enterprise-wide migrations typically take 4–8 weeks, including full team training.
Can n8n connect to my old legacy software?
Yes. If your software has an “API” or a database we can access, we can connect it. We specialize in custom integrations for systems that don’t have standard “plug-and-play” connectors.
What happens after the project ends?
We provide a full handover with training and runbooks. We also offer ongoing support packages if you want us to monitor and update your workflows as your business grows.
