n8n

n8n workflows, built to run your business in the background.

n8n is a workflow automation platform that teams can run in the cloud or host on their own infrastructure. It connects apps, handles complex logic and can orchestrate AI models inside a workflow, which makes it a strong foundation for agents that do real work. We design, build and maintain n8n workflows as part of our agentic automation work, so the analysis and drafting happen automatically while experienced people stay in charge of the decisions.

Every part of n8n, designed and working together

Your n8n setup

We start by mapping the processes worth automating and reviewing any workflows you already run. You see what is reliable, what is fragile and whether cloud or self-hosting suits your data, security and budget, with a prioritised plan to move forward.

An AI agent for your n8n workflows

Every automation programme we run comes with an agent that watches your n8n executions around the clock. Ask what failed, what slowed down or what changed this week, and get a clear answer drawn from live workflow data.

It traces problems, drafts fixes and suggests improvements in minutes. Our team reviews every change before it is deployed, so no workflow, credential or AI step changes without a person checking it and signing it off.

You
Why did the enquiry triage workflow slow down this week?
Enquiry volume rose and each one is now being summarised twice by two branches. I have prepared a change that merges them and listed the executions affected for review.
You
Which workflows have failed most often recently?
The order sync workflow fails when a product has no SKU. I have drafted a check that routes those orders to a review queue instead of stopping the run.

Why teams run n8n with Vertical

n8n gives you a great deal of control. We bring the process design, engineering care and marketing knowledge that turn that control into automation you can depend on.

Built around the process

We map how work really flows before building, so workflows remove genuine effort and reflect how your team actually operates.

Agents with boundaries

AI steps get clear instructions, limited tools and approval points, so agents are useful without acting beyond what you intended.

Your data, your choice

We help you choose between cloud and self-hosting based on security, compliance and cost, then configure it carefully either way.

Reliable by design

Error workflows, testing and monitoring mean problems surface quickly and are fixed before they reach customers or reports.

Marketing context

We also run CRM, email and paid media, so automations reflect how leads, customers and campaigns should move through your business.

AI with human judgement

Agents do the analysis and drafting at speed. Experienced people decide where automation belongs and approve what reaches a customer.

View case study

A powerhouse in a Power Station.

Vertical is a small, senior team of strategists, creatives and performance marketers based at Battersea Power Station in London, with clients and colleagues around the world. Strategy, creative and performance come from one team, with AI built into how we plan, make and measure.

The building has stood on the Thames for the best part of a century, and for fifty years it kept London’s lights on. We like the precedent.

n8n questions, answered

What is n8n and what is it used for?

n8n is a workflow automation platform. You build workflows by connecting nodes for different apps and actions, then add logic that decides what happens in each case. It can run in the cloud or be self-hosted on your own servers, and it includes nodes for working with AI models. Businesses use it to sync data between tools, process leads and orders, run reports, triage enquiries and build AI agents that handle repetitive research and drafting.

What does an n8n agency do?

An n8n agency designs, builds and maintains automation on the platform. At Vertical that covers process mapping, workflow design, AI agent workflows, integrations, hosting setup, error handling, monitoring, documentation and training. Because we also run CRM, email, paid media and websites, we understand the marketing and sales processes your workflows support. You get automation that reflects how your business works, maintained by a team that knows the commercial goals behind it.

Should we self-host n8n or use the cloud version?

It depends on your data, your team and your priorities. The cloud version is simpler to start with because hosting, updates and uptime are handled for you. Self-hosting keeps data inside your own environment and gives more control, which can matter for sensitive information or strict compliance needs, but it requires someone to manage servers, security and upgrades. We help you weigh those trade-offs and can set up and maintain either option.

Can n8n build AI agents?

Yes. n8n can connect to AI providers such as OpenAI and Anthropic and give a model access to tools, data and memory within a workflow. That makes it possible to build agents that research a lead, summarise a conversation, classify an enquiry or draft a response. We design those agents with clear instructions, limited permissions and approval steps, so they are genuinely useful without acting beyond what you intended. For bespoke builds, see our <a href="/services/ai-solutions-development" class="vb-inline-link">AI solutions development</a> service.

Is n8n better than Make or Zapier?

Each suits different needs. Zapier is very approachable and quick for simple automations. Make offers a visual canvas that handles complex processes at a sensible cost. n8n gives developers more control, supports custom code and can be self-hosted, which suits teams with technical needs or strict data requirements. We work with all three and recommend the one that fits your processes, your team and how much control you need.

How do you keep n8n workflows reliable?

We build error handling into every workflow, with retries for temporary problems, error workflows that alert the right person and safe routes for unexpected data. Before launch, we test with realistic examples and edge cases. Afterwards, we review executions regularly, watch for slowdowns and keep credentials and nodes up to date. When something does fail, we can see exactly what happened and rerun affected items once it is fixed.

Can n8n connect to our existing tools?

Usually, yes. n8n has built-in nodes for many CRMs, email platforms, ecommerce stores, databases and productivity tools, and it can reach almost anything with an API through HTTP requests or webhooks. We connect tools such as HubSpot, Pipedrive, Klaviyo, Shopify and your own databases, so leads, customers and orders move between systems with the right fields and owners, and your team stops copying information by hand.

Will our team be able to manage the workflows?

Yes. We name and document every workflow clearly and train your team to monitor executions and request changes. Some clients have developers who want to extend workflows themselves, and we make that straightforward with tidy, modular builds. Others prefer us to handle everything. Our <a href="/services/ai-training-and-adoption" class="vb-inline-link">AI training and adoption</a> work helps teams use agents and automation with confidence.

How do we get started with Vertical?

Start with a conversation about the processes that take the most time or cause the most errors today. If you already run n8n, we usually begin with a review of your workflows and hosting, then share a prioritised plan. If you are new to it, we map your processes and recommend where to begin. We will be honest about where automation will genuinely help and where a simpler change would serve you better.

Bring us the ambition. We’ll build the system behind it.
