Product engineering studio · Mauritius
Serious software for every stage of a business.
We build custom software, modernise the systems you depend on and put AI agents to work — on top of what you already run, agreed in writing, and handed over so your team can run it.

Services
Four ways to work with us.
Build something new, fix what you have, put AI to work, or get a straight answer before you spend.
Build
New products, portals and internal tools — web and mobile, with AI features where they pay for themselves.

Modernise & integrate
Replace what slows you down, in stages. Connect what already works — ERP, accounting, warehouse.

AI agents & automation
Agentic AI that reads across your systems, prepares the work and asks a person before anything changes.
- AI agents
- Automation
- Evaluation
Technical leadership
Fractional CTO, technical due diligence and AI roadmaps for founders, boards and investors.

Agentic AI
AI agents that ask before they act.
The model plans; your systems calculate. Numbers come from your ERP and your rules, never from the model’s memory.
Most AI projects stall somewhere between the demo and the ledger. We build agents the way you would want a new colleague to work: they read widely, show their evidence and prepare the work — and a person approves anything that changes your records.
- Every proposal shows its sources
- A person approves every change to your records
- Every step is logged and can be reviewed
- Measured against your real cases before launch

Your software is falling behind your business
Internal tools held together with spreadsheets, a legacy system that’s expensive to keep alive, hours lost copying data between systems. We build the next version — connected to what’s already there, with AI where it takes routine work off your team.
Talk about your systemsWhat this usually looks like
- Internal tools that retire the spreadsheets
- Legacy systems modernised in stages, with a way back
- AI agents that prepare routine work for approval

Build
You have a window to prove something works
When the problem is real and the scope can be honest, we take a product from first call to launch — and leave you with something you can keep building on.
Talk about your productWhat this usually looks like
- An honest scope before a line of code
- Every screen designed in every state
- AI features only where they earn their place
Scope and dates agreed in writing first
Technical leadership
You need a clear-eyed technical read
Independent judgement on a target’s architecture and its AI claims, a roadmap that has to hold up, or technical leadership through a transition.
Talk about a decisionWhat this usually looks like
- Technical due diligence, AI claims included
- Architecture and roadmap reviews
- Fractional CTO through a transition
Findings in writing, in plain language

How we work
One plan, in writing, and a date on the wall.
Agreed in writing
Scope, acceptance criteria and dates on one page, approved by you before any build starts.
Designed in every state
Empty, loading, error and done — every screen drawn before it’s built.
Tested before it ships
Every change is tested and independently reviewed before it reaches your people.
Released with a way back
Every release can be rolled back. Nothing goes out without one.
A written update, every week
What shipped, what’s next and what’s at risk — on one page.

Questions
Questions we hear first
What does Nova Aurisia do?
We’re a product engineering studio in Mauritius. We build custom software, modernise and connect existing systems, build AI agents that work inside your operations, and provide technical leadership for founders, boards and investors.
Do you work with startups and small companies?
Yes. We work with founders on a first version, with small teams that have outgrown their spreadsheets, and with larger companies. The method is the same at every size: scope, price and dates agreed in writing before we build, and software handed over so you can run it without us.
Do you build AI agents for businesses?
Yes. We design and build agentic AI that reads across your systems, prepares work such as matches, quotes and replies, and asks a person to approve it before anything changes your records.
Do we have to replace our ERP or other systems?
Usually not. We keep what works, replace what doesn’t in stages, and connect the rest. Many projects start by building on top of the systems you already run.
Do you work in French?
Yes. Calls, documents and the software itself, in English or French.
How does a project start?
With a free working call. You bring the problem; you leave with a one-page memo on how we would approach it — whether or not you work with us.
Tell us what you’re trying to ship.
The first call is a working session, not a pitch. Bring a product you can’t size, a system you’ve outgrown, a process you’d like an agent to take on, or a decision you can’t make — and leave with a one-page memo on how we’d approach it.
