“We have a notebook that works and no system”
The model is real; the application, the integration and the users are not.
Mentis · Services · Custom AI application development
From a model that works to a product your people actually use
We design and build the full application around the AI — document pipelines, APIs, integrations, interfaces, optimization engines — secure, tested, documented and handed over with the code. One team, from the first sketch to the support line.
When to call us
Sound familiar?
“Generic AI tools don’t fit how we work”
Your process, your data model, your systems — off-the-shelf tools make you work around them.
“It has to plug into the ERP, the DMS, the CRM”
Value appears where the decision is taken, not in a separate portal nobody opens.
What you get
Outcomes, not deliverables first
End to end, one team
Data, model, backend, interface and operations from the same senior people — no hand-offs where quality leaks.
Fits your systems
Integrations with what you already run, identity and permissions included, in the workflow where work happens.
Yours to keep
Source code, documentation, tests and a team trained to own it — no lock-in, no black box.
What we deliver
The scope you can actually sign
Product discovery & UX
Who uses it, for which decision, in which screen — prototypes validated with real users before code.
Architecture & security design
Data flows, zones, authentication, secrets, audit — reviewed with your IT security from day one.
Backend, APIs & integrations
Services around the model; connectors to ERP, CRM, DMS, ticketing and identity providers.
Interfaces
Web, back-office and mobile interfaces designed for the task — including the human-oversight screens the AI Act expects.
Optimization engines
Routing, scheduling and resource-allocation engines tailored to your constraints where a predictive model is not the answer.
QA, documentation, hand-over & support
Automated tests, technical and user documentation, deployment on your infrastructure, support and evolution for as long as you need.
How it runs
Fixed scope, fixed price per phase — you decide at each step.
- 1
Discovery (1–2 weeks)
Users, decisions, systems, constraints — a validated prototype and a phased, fixed-price plan.
- 2
Phased build
Each phase a working increment on your infrastructure, fixed price, demoed to real users.
- 3
Launch & support
Roll-out, training, monitoring — and a team that is around after go-live.
Regulation & sovereignty
Security, GDPR and oversight — built in
Security-by-design reviews with your IT, DPIA support for personal data, audit logs and the human-oversight interfaces the AI Act requires for high-risk use — designed into the application rather than retrofitted. Deployed on your cloud or on-premise, never on ours.
Questions
Which technology stack?
Python for the AI and data layers, modern web stacks for interfaces and APIs, containers for deployment — chosen to fit your team’s skills so you can maintain it. We do not impose a proprietary platform.
Is it fixed price?
Discovery is fixed price; the build is phased with a fixed price per phase, scoped at the end of discovery. You decide phase by phase.
Do you maintain it afterwards?
If you want: support, monitoring and evolution on a retainer. If not: full hand-over with documentation, tests and training.
Can you take over an existing prototype?
Yes — often the fastest route. We audit it, keep what is sound, and industrialise the rest.
