AI Built Around Your Business. Not the Other Way Around.

Generic AI tools are built for everyone, which means they’re perfect for no one. If you’ve tried ChatGPT plugins, off-the-shelf automation tools, or platform-native AI features and found them too limited, too disconnected, or too far from what you actually need — custom AI is the answer.
CentNine designs and builds bespoke AI solutions that integrate directly into your existing systems, understand your specific processes, and automate the workflows that matter most to your business. No workarounds. No compromises.

When Generic AI Tools Aren't Enough

Off-the-shelf AI is powerful — until it isn't.

The reality

Off-the-shelf AI tools are excellent for many tasks — drafting emails, summarising documents, generating ideas. We use them ourselves.

But they hit a ceiling. When your business needs go beyond what a generic tool can handle, a different approach is required — one built around your data, your systems, and your rules.

Custom AI isn't about technology for its own sake. It's about building something that actually works for the complexity of your operation.

You need AI that understands your proprietary data, processes, or terminology

You need AI integrated directly into your CRM, ERP, or internal systems

You need AI to take actions, not just generate text

You need outputs that follow your specific business rules consistently

You need full data privacy and control — no data leaving your infrastructure

When any of these apply, custom AI isn't a luxury — it's the only option that actually works.

Custom AI Solutions We Deliver

Purpose-built for your systems, your data, your rules.

Custom LLM Integrations

Connecting large language models (GPT-4, Claude, Llama) directly to your business systems — so AI can read your data, apply your rules, and produce outputs that are actually useful in your context.

Internal AI Tools

Custom-built AI tools for your team — proposal generators, document analysers, research assistants, onboarding tools, training systems — built for your workflow, your data, and your specific needs.

AI-Powered Workflow Automation

End-to-end agentic AI services that automate multi-step business processes. Input comes in, AI processes it, decisions are made, actions are taken across multiple systems — without human involvement at each step.

Predictive Analytics & AI Models

Custom AI models trained on your historical data to predict demand, identify churn risk, score leads, forecast inventory, or flag anomalies — before they become problems.

AI-Powered Dashboards

Intelligent reporting dashboards that don't just show data — they surface insights, flag issues, and make recommendations. AI that tells you what the numbers mean, not just what they are.

RAG Systems

AI systems that answer questions from your own documents, knowledge bases, or databases — accurately and with full source attribution. Ideal for customer support, internal knowledge management, and compliance.

How We Build Custom AI Solutions

A structured path from discovery to continuous improvement.

Step 1
Discovery & Requirements
Week 1–2

Deep-dive into your business processes, data infrastructure, and existing tech stack. We map what the AI needs to know, access, and do.

Step 2
Architecture Design
Week 2–3

We design which AI models to use, what integrations are needed, how data flows, and how the system connects to your existing tools.

Step 3
Development
Week 3–8

Our AI engineering team builds the solution in stages with regular check-ins. You review and provide feedback throughout the entire process.

Step 4
Training & Fine-Tuning
Week 6–10

We train the AI on your specific data, test it against real-world scenarios, and fine-tune until outputs meet the quality standard you need.

Step 5
Testing & QA
Week 9–12

Extensive testing across edge cases, security, performance under load, and integration stress testing. We don't deploy until it works reliably.

Step 6
Deployment & Improvement
Week 12+

We deploy into your environment and monitor closely. As usage grows and your business evolves, we iterate and improve as part of the ongoing retainer.

Section 6 — Integration Capabilities

Works With the Tools
You Already Use

Custom AI doesn't mean rebuilding your tech stack. We connect directly to your existing platforms, databases, and workflows — so your team keeps working the way they already do.

If it has an API, we can likely integrate with it. If it doesn't, we discuss your options.

Enterprise-Grade Security.
Your Data Stays Yours.

When you build custom AI, data privacy isn't an afterthought — it's the entire design brief.

Security-first architecture

Built for privacy from the ground up.

Every system we build treats your data with the same rigour as enterprise financial infrastructure. Security isn't a feature — it's the foundation every decision is made on.

No shared model training Your data never trains shared or public AI models — ever.
On-premise deployment Full on-site deployment options for maximum data control.
End-to-end encryption All data encrypted in transit and at rest, without exception.
Role-based access controls Granular permissions built into every system we deliver.
GDPR & compliance-ready Regulatory compliance baked into the architecture from day one.
Full audit trails Every AI decision and action logged, traceable, and reviewable.

Frequently Asked Questions

ChatGPT is a general-purpose tool. It doesn't know your business, your data, your rules, or your systems. Custom AI is trained and configured specifically for your context — so it produces outputs that are actually useful in your workflows, integrated into your systems, and operating under your business rules consistently.
Custom AI makes sense when you have a clear, repeated process that currently requires significant human time and where the quality and speed of that process directly affects revenue or customer experience. This applies to businesses from 10 employees to 10,000. The trigger is usually a specific bottleneck, not a company size.
Simpler custom tools: 6–8 weeks. Complex agentic ai services with multiple integrations: 10–16 weeks. Multi-system enterprise solutions: 16–24 weeks. We scope accurately at the start and give you a realistic timeline before any commitment.
Custom AI projects typically start from $15,000 for simpler solutions and scale based on complexity, integrations, and ongoing support requirements. We provide a detailed cost breakdown after discovery so there are no surprises. Most clients see full ROI within 6–12 months.
We do — as part of a monthly retainer. AI models need ongoing monitoring, retraining as your business data changes, and updates as underlying AI technology improves. We handle all of this so you don't need an internal AI team.
Yes — this is a core part of what we do as standard ai agent services. See our integration capabilities section above. If your system isn't listed, tell us and we'll advise.
Most businesses have more usable data than they realise — in emails, documents, spreadsheets, and system logs. We help you assess and prepare your data as part of the discovery process. In some cases, we start with a smaller-scope solution and expand as data quality improves.
No. We design every solution with a non-technical end user in mind. Your team interacts with the AI through simple interfaces — dashboards, Slack, email, or your existing tools. The technical complexity is hidden under the hood. We handle it.
