What is AI Development?
Custom AI development is building an AI system around your own data, workflows, and systems instead of buying an off-the-shelf tool. It runs from use-case discovery and model selection through building the application, connecting it to your systems, and keeping it reliable in production. You own the result.
When Does Custom Earn Its Cost?
Off-the-shelf is often the right answer, and we will tell you when it is. Custom earns its cost when:
- The workflow is yours alone, and no product on the market covers it.
- The data the system needs cannot leave your systems or your security perimeter.
- The workflow is a real differentiator rather than a commodity process.
- Generic tooling creates more friction and rework than it removes.
- You need to own the code, the models, and the IP outright.
Our Custom AI Development Services
What you can engage us to build. Most clients start with one workflow on a fixed scope and expand once it works.
Your First AI System Live in Weeks
Start with one high-value workflow on a fixed scope. In a 30-minute call we'll scope it, agree the number it has to move, and show you the path to production.
Scope your first buildCustom AI Systems We've Shipped to Production
Built on real data, running on real systems, measured against a number agreed before the build.

Custom AI Solutions by Industry
We shape our AI development solutions around the sectors we know, from the use cases down to the governance, because a claims workflow and a production line do not run the same way. Here is what we build in each.
Read claims documents as they land, compare and quote policies, and give underwriters the research they need.
Why Pinnasys as Your Custom AI Development Company
There are plenty of firms selling AI development services. Here is what you get with us that you will not get from a generalist agency or a Tier-1 firm.
A Claude Service Partner with a certified team
We are an Anthropic Claude Service Partner, and our engineers hold Claude Certified Associate, Developer, and Architect credentials.
Production is the deliverable
Our work is judged on systems running on your live data, doing real work, and staying reliable after launch.
Measurable ROI, agreed up front
We capture your baseline before we write code and report against that number, so the return is provable rather than a matter of faith.
AI is all we do
No mobile apps, no blockchain, no side practices. Every engineer here works on AI systems, every day.
Senior engineers on your build
You work directly with the people writing the code. No account layer, no junior bench, no outsourced delivery.
Built for the mid market
Scoped, accessible projects for mid-market companies and AI-native founders, without enterprise minimums.
You own everything we ship
The data, the code, the models, and the delivered solution are yours. IP assignment is in every contract, so your team can run it or evolve it without us.
Fixed scope and price
We scope and cost the work before anyone writes code, so you know the number before you commit. No open-ended billing, no scope drift.

The First Build Is Where the Partnership Starts
Most of our clients start with one workflow, prove the number, and expand from there. We stay through production and into the next build, so someone is accountable for your AI roadmap and not just a deliverable. Book a 30-minute call and we'll map where to start.
Plan your AI roadmapThe Capabilities Behind Our AI Development Solutions
Services are what you engage us for. These are the technical competences that power them, and they cut across every service above.
Generative AI & LLMs
Generative AI software development for assistants, copilots, drafting, and summarisation, grounded in your own content so answers are traceable to a source.
RAG & Retrieval
Pipelines that put your documents, records, and knowledge in front of the model at the moment it answers, with your permissions respected.
Document Intelligence
Contracts, claims, invoices, and forms turned into structured data your systems can act on, with every extraction traceable to the page.
300M+ documents processedMachine Learning
AI and machine learning development for forecasting, scoring, classification, and anomaly detection, where a measurable, predictable model beats a language model.
Computer Vision
Object detection, quality inspection, and visual data analysis, turning images and video into decisions.
Intelligent Process Automation
Rules and AI working together, so predictable steps stay deterministic and auditable and only the judgement calls reach a model.
Agentic & Orchestration
Agents that plan and act, and the orchestration layer that coordinates several of them across your systems.
100+ agents deployedIntegration & MCP
Connecting AI to the CRM, ERP, warehouse, and internal tools you already run, on open standards so it stays portable.
MLOps & Evaluation
Deployment pipelines, evaluation suites against real cases, and monitoring for drift, cost, and failure patterns after launch.
The Stack Behind Production AI
Model and framework agnostic, chosen per use case. Claude is where our deepest expertise sits as a Claude Service Partner, and MCP is how we keep integrations open rather than locked to one vendor.

OllamaThe Production Path for Custom AI Development
Our framework for getting AI live and keeping it there. Every stage ends with something you can check, and each one has to earn the next.
Free discovery call
Qualify the Work
- Map the workflows and rank them by value and feasibility
- Say plainly where custom AI fits and where a product or simpler automation wins
- Agree the one workflow worth starting with
You leave with:Your highest-value use case, and an honest answer on the rest.
Before any build
Set the Baseline
- Measure what the workflow costs you today, in hours, spend, or error rate
- Agree the number the system has to move
- Define what success and failure both look like
You leave with:A number to judge us by, agreed before we write code.
Design phase
Design with Guardrails
- Choose the architecture, the models, and the data the system will use
- Set where a human signs off and what the system may never do alone
- Plan access, audit trails, and the security perimeter
You leave with:An architecture and a governance plan, decided together.
Fixed-scope pilot · weeks
Build One Workflow
- Build narrow and deep on the workflow you chose
- Connect it to your real systems inside your security perimeter
- Wire in evaluation and observability as we build, not after
You leave with:A working system in production, not a demo.
Against your baseline
Prove It
- Run it against real cases, edge cases, and failure modes
- Report the result against the number we agreed in stage two
- Fix what the evidence says to fix
You leave with:Proof it works, or an honest account of what did not.
Ongoing · months
Own It & Expand
- Hand over the solution, the code, and the documentation
- Monitor performance, behaviour, and cost in the open
- Expand to the next workflow only once this one has earned it
You leave with:The data, the code, and the IP. Yours to keep or evolve.
Our Compliance Framework Behind Custom AI Development

Frequently asked questions
Frequently Asked Questions About Custom AI Development
The questions we hear most from mid-market teams and AI-native founders weighing up a custom build.
Custom AI development is the design and build of AI systems around your own data, workflows, and systems, rather than buying an off-the-shelf tool. It covers use-case discovery, model and architecture selection, building the application, integrating it with your systems, and running it in production with evaluation and governance. The output is a system that fits how your business actually works, and that you own.
