Profile
Jack is a software engineer based in Invercargill, New Zealand. He builds the group's products himself, from the app to the systems behind it, and he is the person accountable for them.
He is the sole director of Bryder Holdings Ltd, a New Zealand registered limited company, and of KiwiBudget Limited, the company that runs KiwiBudget. Bryder owns the businesses, and Jack builds and runs them on its behalf.
Right now that means KiwiBudget, a budgeting app for New Zealanders launching on 16 November 2026, and setting up Bryder Commerce.
Invercargill is home, and the work reaches people across the rest of New Zealand. Software work is happily remote, so where you are matters less than it used to.

The work
Both belong to Bryder Holdings Ltd. Jack builds the products and keeps them running.
A budgeting app made for New Zealand money. It connects to NZ banks through a licensed open banking provider, sorts spending on its own, and answers the only question that matters: what can I actually spend until payday. It understands StudyLink, IRD tax codes and KiwiSaver, because a budget built for another country's money never quite fits.
Launching 16 November 2026, starting with students.
The group's ecommerce company, being set up now. Its name is reserved on the Companies Register, and it will be wholly owned by Bryder Holdings Ltd.
