Private Intelligence
Nobody knows how A.I. is going to turn out. But we do know the difference between using it badly and using it well — to elevate your work, protect your data, and deliver real value to your clients.
Intelligence That Stays Inside Your Business
Public services like ChatGPT and Copilot are powerful — but every prompt, every document, every question passes through public cloud models where data can be retained, used for training, or stored outside the UK. For businesses handling legal documents, financial data or client information, that is a problem.
We build private intelligence applications that run entirely within your own environment. Same capability, but your data never leaves your control and is never retained by another company. We handle infrastructure, deployment, model selection and ongoing development — you get working tools without needing to commit to platforms or surrender your data.
What You Can Do With It
Real examples of applications we have built or are building — all running privately, connected to the client's own platforms.
Process automation
Identify repetitive workflows and build intelligent tools that handle them privately, accurately, consistently
Incident response
Triage security alerts, draft containment plans, prepare regulatory notifications from your own playbooks
Compliance
Map operations against ISO 27001, Cyber Essentials or GDPR. Prepare audit responses automatically
Management reporting
Pull data from multiple platforms into plain-language summaries your directors can actually read
Accountancy assistant
Review trial balances, flag miscoded transactions, monitor Companies House deadlines, draft client emails
Finance & HR
Cross-check payroll against leave records, flag expense anomalies, draft internal communications
Contract review
Compare contract versions, extract key clauses, flag risks — without documents leaving your environment
Knowledge base
Your documentation, searchable by conversation. Instant answers from your own procedures and policies
Email drafting
Read incoming mail, summarise it, draft replies in your tone of voice. Review and send, not write from scratch
What if we had a system that read every incoming tender, pulled our best previous answers, and gave us a head start on the response?
What if every lead that came in arrived with a full profile of the client, their business and their background — letting us understand how to communicate with them before we have even put pen to paper?
What if we could just describe a problem and have a tool built around it within weeks? What will your people build first?
With 30 years of systems experience, we can help you to see what's possible.
Common Questions
Is it as capable as ChatGPT / Claude / Gemini / Copilot?
Yes. We use whichever model is best for the job — and we do not tie you to any single provider. If a better model appears tomorrow, we switch — and none of your data is retained by the model providers.
What happens if we stop?
Everything is yours. Applications, data, configuration — all of it transfers to another supplier, or you take it in-house. We will even help you recruit. No exit fees, no hostage-taking.
How do we get started?
Book a call. We work out where intelligence can make the biggest difference, then build the first tools with you — typically within weeks, not months.
Pricing
Infrastructure — typically around £300/month
Your own dedicated server, sized to your usage. Scale up or down as you need. No lock-in contracts.
Development — from £880/month
Our base rate covers weekly reviews and demonstrations as we integrate feedback and work with new ideas from your staff and our team, letting development proceed with pace whilst maintaining cultural decorum. This doesn't need to be that fast. As you want more from the tools, we scale up with you.
Your Systems, Connected Privately
We integrate with the platforms your business already uses — Xero, Microsoft 365, Google Workspace, Salesforce, HubSpot, Companies House, Breathe HR, Sage, QuickBooks, Slack, Dropbox, SharePoint, Mailchimp, Stripe, Trello — anything we can get data from. If you can read the data, so can our agents. Every connection runs through your own private infrastructure.
If the platform you rely on has a modern programming system (API), we can connect it. If they're still in the stone age, we can usually find a way to get the data you need to get the job done.
We Are A.I. Optimists
There is a lot of fear around artificial intelligence, and some of it is justified. But used well, A.I. is one of the most powerful tools modern organisations have ever had access to. It can give your team capabilities that were either flat impossible or a £75,000 software project just four years ago. We are here to make sure you use it well, use it safely, and use it to genuinely improve the work you do for your clients.
Value Your Work
Agentic tools are remarkable. But an AI-generated email smashed lazily into the inbox of a client is not the right way to use this technology. The heavy lifting should happen behind the scenes — the finished work needs to be something you're happy to own.
We help you build a culture where people use intelligence tools to elevate their craft, not replace it. The agent does the groundwork. Your people polish, refine and put their name to something they are proud of.
Real Experience
Our technical director very much enjoyed a degree in Computing with Artificial Intelligence in 2001 and has been building software professionally for over 30 years. We have been through enough technology hype cycles to know the difference between genuine capability and marketing BS.
