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.

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.
Most AI builds stall between the demo and the deployment. Pinnasys is set up to close that gap, with certified Claude engineers, fixed scope, and outcomes you can measure.

We are an Anthropic Claude Service Partner, and our engineers hold Claude Certified Associate, Developer, and Architect credentials.
Our work is judged on systems running on your live data, doing real work, and staying reliable after launch.
We capture your baseline before we write code and report against that number, so the return is provable rather than a matter of faith.
You work directly with the people writing the code. No account layer, no junior bench, no outsourced delivery.
Scoped, accessible projects for mid-market companies and AI-native founders, without enterprise minimums.
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.
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.
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.
Book a Discovery CallServices are what you engage us for. These are the technical competences that power them, and they cut across every service above.
Generative AI software development for assistants, copilots, drafting, and summarisation, grounded in your own content so answers are traceable to a source.
Pipelines that put your documents, records, and knowledge in front of the model at the moment it answers, with your permissions respected.
Contracts, claims, invoices, and forms turned into structured data your systems can act on, with every extraction traceable to the page.
300M+ documents processedAI and machine learning development for forecasting, scoring, classification, and anomaly detection, where a measurable, predictable model beats a language model.
Object detection, quality inspection, and visual data analysis, turning images and video into decisions.
Rules and AI working together, so predictable steps stay deterministic and auditable and only the judgement calls reach a model.
Agents that plan and act, and the orchestration layer that coordinates several of them across your systems.
100+ agents deployedConnecting AI to the CRM, ERP, warehouse, and internal tools you already run, on open standards so it stays portable.
Deployment pipelines, evaluation suites against real cases, and monitoring for drift, cost, and failure patterns after launch.
Model- and framework-agnostic, chosen per use case. Claude is where our deepest expertise sits as a Claude Service Partner. Our AI software development services use MCP to keep integrations open. This custom AI development approach avoids locking you to one vendor.
Hugging FaceOur 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.
Custom AI runs on your real data and acts on your live systems, so trust is the whole game. Five pillars govern every build.


You keep ownership of your data throughout, and you own the code, the models, and the delivered solution. Encrypted in transit and at rest. We do not train shared models on your data.


Least-privilege access so a system touches only what a task requires, a secure development lifecycle, and prompt-injection defences on anything that reads outside input.


You set the autonomy level. Sensitive actions need human approval, every decision is logged and traceable, and evaluation runs continuously against real cases.


We build framework-agnostic on open standards like MCP, so the solution stays portable. A standard NDA and clear IP assignment come with every build.


Systems run inside your security perimeter with scoped credentials on your cloud, so your team can run or evolve them with or without us.

You keep ownership of your data throughout, and you own the code, the models, and the delivered solution. Encrypted in transit and at rest. We do not train shared models on your data.




We work under an NDA from the first conversation, deploy inside your cloud, and hand over the code, the models, and the IP. Ask us anything about how your data is handled before you commit to anything.

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.
An AI development company designs, builds, and runs AI systems for other businesses. That covers working out which problem is worth solving, choosing the models and architecture, building the software, connecting it to the systems you already run, and keeping it reliable once it is live. A good one also tells you when you do not need a custom build.
We scope and price each project before any code is written, so you get a fixed number rather than an open-ended range. Most clients start with one workflow on a fixed-scope pilot, which keeps the first commitment small and the return measurable. Cost follows the number of workflows, the systems we integrate with, and how ready your data is. You will leave a 30-minute call with a scoped, costed use case.
A well-scoped first system usually reaches production in weeks, not quarters, because we start narrow and deep on one workflow. Larger programmes run longer, but they run as a series of scoped stages rather than one long build, so you see a working result early and decide whether to expand.
Yes. You own the data, the code, the models we build for you, and the delivered solution. We work under an NDA from the first conversation, and IP assignment is part of every contract. There is no scenario where you need our permission to keep running your own system.
Yes. Most of our work connects AI to systems that already exist, including CRMs, ERPs, data warehouses, ticketing, and internal apps. We build framework-agnostic on open standards like MCP, and we deploy inside your cloud and your security perimeter rather than moving your data somewhere new.
An API gives you a model. A product gives you someone else's workflow. A custom build gives you a system that knows your data, follows your rules, connects to your tools, and is measured against your numbers. Off-the-shelf is the right answer more often than vendors admit, and we will say so if it fits your case. Custom earns its cost when your workflow is a real differentiator or no product covers it.
You do not need perfect data. Most useful builds start from messy, inconsistent, or partly structured data, and part of the work is assessing what you have and preparing it. What matters more is that the data is accessible, that someone owns it, and that we can agree what good output looks like. Our discovery stage exists to establish exactly this before anything is built.
We qualify the use case first and capture a baseline, so there is a number to judge the result against. Then we ship one workflow on a fixed scope and measure it against that baseline. If the evidence says it did not work, you get an honest account rather than a bigger invoice. That is why the first commitment is deliberately small.
We ground outputs in your own sources with retrieval, constrain what the system is allowed to do and say, and run evaluation suites against real cases and edge cases before go-live. In production we monitor behaviour, cost, and failure patterns continuously. Where the risk of a wrong answer is high, a person approves the action rather than the system acting alone.
Your data stays yours, encrypted in transit and at rest, and we do not train shared models on it. Agents and applications run inside your security perimeter with least-privilege access, so a system only touches what a task requires. Access is logged and auditable.
You choose. Because you own the code and the documentation, your team can run it without us. Most clients keep us on for monitoring, evaluation, and expansion to the next workflow, but that is a decision you make on the evidence, not a dependency we design in.
Ask for systems running in production, not demos. Ask who owns the code and the data afterwards. Ask what number the work is measured against, and whether they capture a baseline before building. Ask whether the people who scope it are the people who build it. Then check whether the answers are specific enough to hold them to.
A single conversation can save you months of guesswork. Book a call and get a clear use case, a grounded ROI estimate, and a candid answer, even if the answer is no.
