Product Development Culture

We are problem solvers, not ticket takers. We champion creative problem-solving and value autonomy, trust, and impactful outcomes over rigid processes. Delivering improvements rapidly, we engage in iterative 6-week cycles, addressing user needs and enabling technical innovation - balancing technical debt, bugs, and team growth. We are a continuous delivery focused group, shipping changes to production 150+ times per month.

At our core is the customer. Every solution we deliver is crafted with customer success in mind, building relationships that go beyond transactions and ensuring that as team members, we all prioritise customer success in every aspect of our work. We build software that delivers value for our users and resist the urge to over-engineer our solutions. We let our users and the data tell us where we go next.
