What we do.
We take a project from the first workshop to the support call. You deal with the senior people doing the work the whole way through.
| Service | What it covers | What you get |
|---|---|---|
| 01Discovery and service design | User research, process mapping and prototypes tested with the people who'll use them, before anyone commits to a build. | A tested prototype, a costed delivery plan and a clear go or no-go. |
| 02Web applications and platforms | Case management, portals, operational systems and internal tools, built for the people who use them every day. | A production system that's documented, accessible and secure. |
| 03Integration and APIs | Connecting what you already run: finance, CRM, identity, legacy databases and third-party services. | One source of truth, no double-keying and an audit trail across systems. |
| 04Responsible AI | Assistants and agents that search, summarise, flag and draft, with a person approving every action. | Hours saved, answers drawn from your own records, and no action without approval. |
| 05Modernisation and data migration | Replacing spreadsheets and ageing systems, and moving data across in stages rather than one risky cutover. | Legacy retired, clean data and no lost history. |
| 06Support and improvement | Hosting, monitoring, security patching and a running list of improvements under an agreed service level. | Agreed response times and a system that keeps getting better. |

01 The problem
Four systems, one business
Our founders ran a $5M+ wholesale operation with stock in one spreadsheet, quotes in another app and purchasing in a tracker nobody updated. The real answer lived in someone's head.
-
02 Why it mattered
None of it talked
The shelf said 31 when the sheet said 48. Quotes went out without a stock check. Problems surfaced only after they had cost money.
-
03 What we built
One record, with an AI that notices
Stock, quotes, purchasing and sales write to the same record. Centra AI reads all of it, flags what's about to go wrong and drafts the fix for a person to approve.
-
04 The result
Live in a day, not a quarter
Customers are up and running in less than a day. More than 20 alerts run from the moment data is connected, and every AI action waits for a person's approval.
Swap stock for cases, warehouses for regional offices and purchase orders for approvals. It's the problem most organisations are trying to solve.
Responsible AI
AI that drafts. People decide.
Public agencies are right to be careful with AI. So are we. Everything we build follows the rules we set for our own product.
- Approval on every action
- Nothing is sent, saved or changed until a person says yes.
- Irreversible actions stay human
- Our AI can't post, dispatch, approve or delete. That's by design, not a setting.
- Answers from your own data
- It works from your live records, not a report someone ran last month.
- Open about where AI is used
- People can see when a draft came from AI, in line with the Public Service AI Framework's focus on transparency.

Waiting for your OK
How we work.
Four short, visible stages. You decide at the end of each one whether to carry on, change direction or stop.
-
01
Discover
We spend time with the people doing the work and map where the real answer lives, before we draw a single screen.
-
02
Prototype
A working slice tested with real users, so you decide whether to go ahead with evidence, not a long specification.
-
03
Build
We build in small increments and show you working software as it comes together, so changing course stays cheap.
-
04
Run and improve
Hosting, monitoring, support and improvements, with documentation and code that belong to you.
Built to government standards.
The standards we build to on every project. Ask us for the detail behind any of them.
-
Accessibility
WCAG 2.2 AA
The level the NZ Government Web Accessibility Standard requires. We design and build to it from the first screen.
-
Security
Independently tested
Security designed with the NZ Information Security Manual as our reference, and an independent penetration test before go-live.
-
Privacy
Privacy Act 2020
Privacy built in from discovery, collecting only what's needed, with support for your privacy impact assessment.
-
Artificial intelligence
Human approval, always
A person approves every action an AI proposes. Irreversible actions stay human-only.
-
Ownership
Your code, your data
The code, data and documentation we make for you are yours, with a clean handover whenever you ask.
-
Insurance
Insured for the work
Professional indemnity and public liability cover, with certificates available on request.
Three things we'll always do.
-
Tell you when something off the shelf will do.
We'd rather lose a build than sell you one you don't need. We hold our own product to the same rule: demand forecasting isn't in it yet, and we say so.
-
Put the people who pitch on the work.
The senior team you meet at the start is the team that designs, builds and supports your system.
-
Give you everything you paid for.
The code, data and documentation we create for you belong to you, and we'll hand them over whenever you ask.
Easy to buy from.
