◆ Custom AI Development Company

Custom AI systems, built for your business and your data

The gap between an AI pilot and a working enterprise system is almost always the same — unreliable outputs, data that isn't ready, no integration path and no owner. We build custom AI that clears that gap: the right technique for your problem, trained on your data, integrated with your stack, and yours to own.

The real blockers

Enterprise AI development challenges we solve

The gap between an AI pilot and a working enterprise system is almost always the same set of problems. Click a panel to see the challenge, how we solve it, and what changes.

01No business impact
Business Outcomes

The model works. The business is unchanged.

Accuracy looks good in the notebook, the demo lands well, and six months later nothing measurable has moved. The model was built to score well, not to change a decision anyone actually makes.

💡Our fix: We start from the decision, not the dataset. Every system is scoped to one business metric, with the baseline captured before we build and the measurement wired in from day one.
1business metric per system
Baselinecaptured before build
Decision-lednot accuracy-led
02Weak data foundations
Data Readiness

Your data cannot support the AI you were sold

Labels are inconsistent, history is short, definitions differ by department, and nobody owns quality. Train on that and the model learns your mess faithfully.

💡Our fix: A data assessment before a single model is chosen — what exists, what it can support, what must be fixed first. Then pipelines and labelling built for the AI, not retrofitted after it.
Honestfeasibility answer upfront
-40%time lost to data rework
Reusablepipelines, not one-offs
03Stuck at PoC
PoC to Production

A proof of concept that cannot be promoted

The PoC was built to impress, not to run — no evaluation harness, no monitoring, no thought given to load, cost or the day the data shifts. Productionising it means starting again.

💡Our fix: We build prototypes on production architecture. Same pipeline, same evaluation, same deployment path — so a successful prototype is a head start rather than a throwaway.

Samearchitecture from day one
Go/no-goon evidence, not opinion
04No integration path
Integration

AI that never reaches the people who need it

The model sits behind a notebook or an endpoint nobody calls. The team it was built for still works in the CRM, the ERP and a spreadsheet — none of which know it exists.

💡Our fix: Integration is designed in from the architecture stage, not bolted on at the end. The output lands inside the tool your team already uses, with the access controls your security team expects.

Why Custom

Off-the-shelf AI is trained on everyone's problem except yours

A SaaS tool trained on generic data cannot learn your product mix, your seasonality or your edge cases. You rent it forever, cannot tune it, and any competitor can buy the same subscription tomorrow.

💡Our fix: Custom AI trained on your data, shaped to your workflow, deployed in your infrastructure — and the IP is yours. Your data advantage becomes a product advantage instead of a vendor feature.

Real results from custom-built AI

Three problems no off-the-shelf product could solve.

Logistics

Demand forecasting built on six years of their own data

Challenge: An off-the-shelf forecasting tool couldn't handle their SKU mix or seasonality. Planners overrode it constantly and quietly went back to spreadsheets.

Solution: A custom model trained on their own order history plus external signals, delivered inside the planning workflow the team already used.

-28%stockouts
+12%forecast accuracy
100%IP owned by client
Manufacturing

Computer vision that catches what the line misses

Challenge: Visual inspection was manual, inconsistent across shifts, and defects were reaching customers.

Solution: A custom vision model trained on their own defect images, deployed to the edge for real-time inspection with human review on low-confidence calls.

94%detection rate
-60%escaped defects
<200msper unit
Financial Services

Document intelligence for a process no vendor sells

Challenge: A niche, high-volume document type with no off-the-shelf tool. Processing was manual, slow and hard to audit.

Solution: A custom extraction pipeline with LLM validation, confidence scoring and human review on exceptions, integrated into their existing workflow.

Frequently Asked Questions

Building an AI system designed around your specific problem, trained on your own data and integrated with your own systems — rather than subscribing to a generic tool. It covers choosing the right technique, engineering the model, validating it, deploying it and keeping it accurate in production.

Off-the-shelf tools are trained on generic data and built for the average customer, which is why they struggle with your edge cases, product mix or terminology. Custom AI learns from your data and fits your workflow — and you own it, rather than renting a capability any competitor can also buy.

Yes. The models, code, pipelines and documentation are yours, in your repositories and your infrastructure. There is no per-seat licence and no dependency on us to keep it running — though most clients choose to keep us on for optimisation.

A working prototype typically takes three to six weeks. A production-ready system usually lands in two to four months, depending on data readiness, the technique involved and how many systems it must integrate with. We start small and expand once value is proven.

Not always. Some problems need years of history; others work from a few thousand well-labelled examples, and some need almost none because they build on foundation models. The data assessment answers this honestly before you commit budget.

No, and this is worth saying plainly. LLMs are excellent for language problems and expensive overkill for many others. Forecasting, scoring, vision and optimisation problems are often solved better, cheaper and more reliably by classical machine learning. We recommend the technique that fits.

Yes — that is usually the difference between a model and a result. We build the APIs, pipelines and middleware to deliver output into your CRM, ERP, e-commerce platform or internal tools, including legacy systems without modern APIs.

We build an evaluation harness before we build the model, then monitor accuracy, drift, latency and cost in production with alerting. When data shifts, retraining pipelines are already in place rather than being invented in a crisis.

You can maintain it yourself, since the code and documentation are yours, or keep us on for monitoring, retraining and optimisation. We hand over properly either way: documented, source-controlled and with your team trained on it.

It depends on the technique, the state of your data and the number of integrations. We price a fixed scope for well-defined projects, or a monthly dedicated team for evolving roadmaps. The discovery call and initial scoping are free.
