AI & Automation

Workflows, agents and LLM systems that take repetitive work off your team.

We design and ship the automation layer of a business: n8n, Make and Zapier workflows, tool-using AI agents, RAG systems grounded in your own documents, and LLM features wired into the software you already run.

What you end up with

  • A written map of every manual handoff we found, and what replaces it
  • Working automations, handed over with documentation and error handling
  • A measured before-and-after on hours and steps removed per week
  • Systems you own, with credentials in your accounts rather than ours

Tools and platforms

  • n8n
  • Make
  • Zapier
  • LangChain
  • LangGraph
  • OpenAI
  • Anthropic Claude
  • Google Gemini
  • Postgres + pgvector
  • Pinecone
  • Redis
  • Supabase
  • Slack
  • HubSpot
  • Airtable
  • Google Workspace

How we think about it

Why ai & automation projects fail

The technical detail that decides whether this work pays back, written for someone who has to sign off on it.

Automation only pays back when it removes a real step

Most automation projects fail at the scoping stage, not the build stage. Someone automates a report nobody reads, or adds a Slack notification to a process that was already fine. We start by watching how work actually moves through the business, who touches a lead, where a handoff waits, which follow-up depends on a person remembering, and then pick the steps where removing manual effort changes a number you care about. Anything we cannot tie to a measurable outcome does not get built.

Choosing the platform is a cost decision, not a feature decision

n8n, Make and Zapier now advertise nearly identical AI capabilities, so feature comparisons are close to useless. What actually separates them at real volume is the billing model: n8n charges per workflow execution and can be self-hosted, Make bills per operation, and Zapier bills per task. On the same process, the monthly gap between the cheapest and most expensive of the three is often five to eight times. That is why we pick the platform after modelling your volumes, not before, and why we will happily recommend the cheaper one even when it means less billable work for us.

Agents need guardrails before they need intelligence

An AI agent that can send email, write to a CRM and move money is a liability with a language model attached. Before we give any agent tool access, we define what it may never do, put human approval on irreversible actions, cap what it can spend, and log every action it takes with the reasoning that led there. The interesting engineering in production agents is not the prompt, it is the failure handling, the retries, the evaluation set, and the cost ceiling.

Retrieval quality decides whether RAG works at all

When a document assistant gives a bad answer, the problem is almost never the language model. It is the retrieval: documents chunked on the wrong boundaries, a vector search that ignores the metadata a human would have used, no reranking step, and no evaluation set to prove a change helped. We treat retrieval as the product and the model as a replaceable part, which also means you can move to a cheaper or self-hosted model later without rebuilding the system.

Questions

Before you book a call

Do we need to replace the tools we already use?

Almost never. The point of an automation layer is to connect what you have. We build against your existing CRM, helpdesk, spreadsheets, accounting package and inbox, and we only recommend replacing a tool when it has no usable API or the licence cost is clearly larger than the integration cost.

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

Self-hosting removes per-execution fees and keeps sensitive data on infrastructure you control, which matters for healthcare and any process touching personal data. It also puts patching, backups and uptime on you. We size that decision against your monthly execution volume and your appetite for running a server, for low volumes the cloud version is usually cheaper once you cost in maintenance.

How do you stop an AI agent from doing something embarrassing?

Three controls, always: a hard allow-list of tools the agent may call, human approval before any irreversible or customer-facing action, and structured logging of every tool call and its result. We also build an evaluation set of real past cases and run it before any prompt or model change reaches production.

Can this work be extended by our own team later?

Yes, and that is the intent. Workflows are handed over in your own workspace with documentation written for the person who inherits them. If you would rather we stay on and maintain them, we do that too, but nothing is built to be unmaintainable without us.
