AI Automation & Integration
Workflows, LLMs and RAG that plug into the tools you already use
We design, build and run AI automations on n8n and Zapier — from simple app-to-app workflows to assistants that answer from your own documents — so your team spends less time on repetitive work and no opportunity slips through.

What we build
Four ways AI can work inside your business
From simple app-to-app automations to assistants that know your business — built on proven tools, connected to the systems you already use.
Workflow automation
n8n and Zapier workflows that connect your CRM, spreadsheets, email, WhatsApp and ERP — with triggers, schedules, webhooks and proper error handling.
LLM integration
Language models inside your workflows: classify enquiries, extract data from documents, summarise conversations and draft replies — with structured outputs, guardrails and human approval where it matters.
RAG knowledge assistants
Assistants that answer from your own catalogues, SOPs, price lists and policies — with source citations — on your website, WhatsApp or internal tools.
AI agents & custom integrations
Multi-step agents that use tools, plus custom APIs, webhooks and nodes for the systems that don't have an off-the-shelf connector.
n8n or Zapier?
We pick the platform that fits — not the one we prefer.
Each option trades off speed, cost, control and data privacy differently. We recommend one based on your volume, your data and who will maintain it.
Zapier
Best for
Simple, low-volume flows your team can maintain themselves.
- Fastest to launch
- 7,000+ app connectors
- No servers to manage
- Easy hand-over to non-technical teams
n8n Cloud
Best for
Complex, branching workflows without running infrastructure.
- Branching, loops and code steps
- Built-in AI and LLM nodes
- Managed hosting and updates
- Far lower cost at volume than per-task tools
n8n Self-hosted
Best for
Sensitive data, high volume and full control.
- Data stays on your own server
- No per-task pricing
- Docker / VPS setup with queue mode
- We handle backups, monitoring and updates
Retrieval-augmented generation
AI that answers from your documents
A general chatbot guesses. A RAG assistant looks up your own material first, then answers — so responses are accurate, specific and traceable.
- Answers grounded in your data, not the internet
- Every answer cites the document it came from
- Access control over who can ask about what
- Stays current as your documents change
Vector stores we use

- Pinecone
- Qdrant

Use cases
Where teams usually start
Most clients begin with one of these — a single workflow that pays for itself — and expand from there.
WhatsApp lead capture & follow-up
Capture, qualify and follow up on every enquiry automatically. Our flagship workflow — see it below.
Invoice & document extraction
Pull fields from invoices, POs and forms with an LLM and push them straight into Sheets, Tally or your ERP.
Support assistant
A RAG-powered bot that answers product and policy questions instantly and hands off to a human when it should.
Email triage & draft replies
Classify incoming email, route it to the right person and prepare a draft reply for review.
Automated reports
Daily and weekly summaries of sales, leads and operations delivered to email, WhatsApp or Slack.
Internal approvals
Quotation, expense and leave approvals that route themselves, remind approvers and log every decision.
Flagship workflow · AI + WhatsApp sales
How many enquiries did your company receive last month that never got a follow-up?
If you don't know the answer, you're probably leaving revenue on the table.
Every day, businesses receive enquiries through:
- Website
- Phone
- Social Media
- Referrals
But somewhere between the enquiry and the sale, opportunities disappear.
- A salesperson forgets to follow up.
- A quotation sits unanswered.
- A customer doesn't receive a response.
- A lead gets buried in WhatsApp.
And eventually, the opportunity is lost.
How it works
Lets Build changes that.
We connect your sales channels and business tools with AI-powered workflows that help your team:
Before Lets Build
Manual and person-dependent
With Lets Build
Automated and tracked end to end
The goal isn’t to replace your sales team. It’s to make your sales team impossible to ignore.

How we engage
Start with one workflow, not a rebuild.
We map the process, prove it works on a small scope, then harden and scale it — and we stay on to monitor and improve it.
Have a process that eats hours every week?
Tell us how it works today. We'll show you which parts n8n, Zapier or an AI assistant can take over — and what it would take to get the first workflow live.
