Custom AI Development
AI built around your business — not the other way round
When off-the-shelf tools won't cut it, we build custom AI solutions tailored to your business. From custom GPTs trained on your knowledge base to autonomous AI agents that complete multi-step tasks — we ship production AI that delivers measurable ROI.
How Custom AI Development Works
Off-the-shelf AI tools — chatbots, voice agents, automation platforms — solve 80% of cases. But there's always that 20%: the workflow that's unique to your industry, the knowledge base that's too proprietary to feed to ChatGPT, the customer experience that needs to feel distinctly yours. That's where custom AI development comes in.
We build production AI systems using OpenAI, Anthropic Claude, and open-source models (Llama, Mistral, Qwen). Our custom builds typically fall into four categories: (1) Custom GPTs trained on your internal documents, processes, and product knowledge — giving your team or customers an AI expert with your specific context. (2) RAG (Retrieval-Augmented Generation) systems that let AI search and answer questions from your private documents, contracts, manuals, or knowledge bases. (3) Autonomous AI agents that complete multi-step tasks — from researching prospects to drafting proposals to scheduling follow-ups. (4) AI-powered features inside your existing software — adding smart search, content generation, or decision support to apps you already use.
We handle everything: scoping, prototyping, building, deploying, and maintaining. Projects typically run from 4–12 weeks depending on complexity. Every build comes with documentation, monitoring, and ongoing support. We're particularly strong at integrating AI into existing systems without rip-and-replace — we plug into what you already have.
What You Get with Custom AI Development
Custom GPTs trained on your knowledge base
We fine-tune or RAG-train AI on your processes, products, manuals, and historical conversations — creating an AI that knows your business as well as a senior employee with 5 years of experience.
Autonomous AI agents for multi-step work
Build AI agents that research, plan, and execute multi-step tasks — drafting proposals, researching prospects, generating reports, even coordinating with other AI systems.
Privacy-first builds with self-hosted options
For sensitive data (legal, medical, financial), we deploy open-source models (Llama 3, Mistral, Qwen) on your own infrastructure. Zero data leaves your network.
AI features inside your existing software
Don't rip and replace your current systems — we add AI capabilities to what you already use. Smart search, AI summarisation, content drafting, and decision support, embedded where your team works.
Production-grade reliability and monitoring
We build with error handling, fallback logic, monitoring, and human-in-the-loop checkpoints. Production AI you can actually trust to run unsupervised.
Ongoing optimisation as models improve
AI capabilities double every 6 months. We continuously upgrade your systems to use the latest models, prompts, and techniques — so your AI gets better over time, not stale.

When do I need custom AI vs an off-the-shelf tool?
+
When do I need custom AI vs an off-the-shelf tool?
+Off-the-shelf wins for: standard chatbots, basic voice agents, simple automations. Custom wins when: (a) you have proprietary data or processes generic tools can't access, (b) you need privacy guarantees off-the-shelf SaaS can't provide, (c) the workflow is unique to your industry or business, or (d) you want to build a defensible AI advantage competitors can't copy.
How much does custom AI development cost?
+
How much does custom AI development cost?
+Custom GPT / RAG systems: £4,000–£15,000. Autonomous AI agents: £8,000–£30,000. AI features in existing software: £3,000–£20,000+ depending on complexity. We always start with a paid discovery sprint (£500-£1,500) to scope properly before quoting the full build.
Can you keep our data private / GDPR-compliant?
+
Can you keep our data private / GDPR-compliant?
+Yes. We offer three privacy tiers: (1) Standard — uses OpenAI/Anthropic with their enterprise data agreements (no training on your data). (2) UK/EU-hosted — using Azure OpenAI in UK regions. (3) Self-hosted — open-source models running entirely on your own infrastructure or our private cloud, zero data leaves your network. We help you pick the right tier based on your data sensitivity.
What's RAG and why does it matter?
+
What's RAG and why does it matter?
+RAG (Retrieval-Augmented Generation) means giving an AI access to your private documents at query time, instead of trying to train them in. The AI looks up relevant info from your docs, then uses it to answer questions accurately and with citations. It's faster, cheaper, and more accurate than fine-tuning for most business use cases.
Will it integrate with our existing systems?
+
Will it integrate with our existing systems?
+Yes — most of our custom builds are explicitly designed to plug into existing systems (CRMs, ERPs, ticketing systems, document stores). We work with what you have rather than asking you to migrate. If your system has any API, webhook, or even just email/file export, we can integrate.
What if AI capabilities improve dramatically after we build?
+
What if AI capabilities improve dramatically after we build?
+Good news: we architect every build to be model-agnostic. When better models launch, we upgrade your underlying AI without rebuilding the system. Clients on our maintenance retainers automatically get model upgrades — most have moved through 3–4 model generations without rebuilding.
