What we build.

Cennix is a software and AI engineering company. We build software and AI agents around your business, with support after launch.

  • Built around how you work

    We start with your people, your process and your data, then shape the software to fit them.

  • AI where it earns its place

    Some projects need AI at the center, some in one feature, and some not at all. We tell you which.

  • See it working first

    We build in stages, so you see a working version before each larger investment.

  • Here after launch

    Hosting, maintenance and improvements when you want them, or a clean handoff when you do not.

What changes when the software fits.

The outcomes clients come to us for. Each project agrees its own measures up front; these are aims, not promises.

  1. Less manual handling.

    Today: Your team copies the same information between spreadsheets, email and three different tools.

    We build:Connected business software, integrations and agents that do the handling, with a person approving what matters.

  2. A clearer view of operations.

    Today: The numbers live in five systems, and nobody fully trusts the weekly report.

    We build:CRMs and dashboards built on one source of truth, showing the figures your team actually uses.

  3. Easier access to information.

    Today: The answers are buried in documents, inboxes and one experienced person's head.

    We build:An AI knowledge system that answers from your own documents and shows the source for every answer.

  4. A product, brought to launch.

    Today: You have the idea and the customers, but no team to build the software.

    We build:A first usable release with clear acceptance criteria, then the production product and the releases after it.

How working with us works.

Four steps, and you can stop after any of them. Some clients only need the plan; others want us to run the software for years.

    Discuss the need

    A short call about what you want to build, and an honest view on whether and how we can help.

    No charge

  4. 4.

    Run it, or hand it over

    We host, monitor and improve it each month, or hand everything to your team. Your choice.

Questions people ask first.

Anything else, ask us directly. A person reads every message.

What does Cennix do?

We build custom business software, software products and tailored AI systems. We also offer solution design before a build, and managed hosting and ongoing engineering after launch.

Who do you work with?

Established companies, founders and startups, across industries. What they have in common is a specific problem or product that off-the-shelf software does not solve well.

Do you only build AI?

No. Much of what businesses need is good software: a CRM, a dashboard, a portal, an internal tool. AI is part of a project when it does the job better than the alternatives.

How does a project start?

With a short conversation about what you want to build. From there, a clear project can be scoped directly. When the solution is not yet clear, Solution Design & Consulting is a separate, scoped engagement that produces requirements, architecture, a roadmap and an estimate.

How is work priced?

Each project is scoped to its requirements and delivered in milestones. Managed hosting and ongoing engineering is an optional monthly engagement with an agreed scope.

Do we need monthly support?

No. Every project delivers a usable result that works without it. You can choose ongoing support from us or a handoff to your own team.

Who works on our project?

Cennix's founder is hands-on with the engineering. For specialist areas such as complex AI or infrastructure, we may bring in specialists, agreed with you in advance.

Who owns what you build?

Ownership and rights are agreed in writing before any build starts, including any existing Cennix components that are licensed rather than transferred.

Do you have case studies?

Not yet. Cennix is a young company and does not publish client work without permission. Orbis, a CRM in development, shows our work on business software; the other examples on this site are labeled illustrative.
