In short

Custom AI agents built on GPT, Claude, Gemini and open-source models, wired into your existing SaaS and internal systems with retrieval, guardrails and full audit trails.

Why UK operators are buying ai agents in 2026
Off-the-shelf chatbots stop at answering questions. Agents finish the job — raising invoices, updating CRM records, drafting quotes, filing tickets — while a human approves every action that matters.
Workflows we automate
Invoice chasing, quote drafting, CRM data hygiene, inbox triage, ticket routing, SLA monitoring, competitor and market monitoring, internal help-desk answers.
The stack we build on
OpenAI GPT-4/5, Anthropic Claude, Google Gemini, Llama and Mistral on Ollama, LangGraph, LlamaIndex, plus native integrations to Xero, Sage, QuickBooks, HubSpot, Salesforce, Pipedrive, Zoho, Slack, Teams, Gmail and Outlook.
Real ai agents use cases
• An AR agent that chases overdue invoices out of Xero with tone-appropriate emails and escalates only when a customer breaks payment terms. • A sales-ops agent that watches HubSpot for stale deals, drafts follow-up emails and books meetings once a rep approves. • A quote agent that reads inbound RFQs, drafts a priced response from your catalogue and hands it to a human for sign-off. • A support-triage agent that reads inbound tickets, tags severity, drafts a first reply and routes anything sensitive to a real engineer. • A compliance-watch agent that monitors regulator publications and flags what your team actually needs to act on.
Outcomes to expect
60–80% less time on repetitive admin, 3× faster response times on inbound work, and full evidence of every decision the agent made or escalated.
