A Wellington finance-ops startup raises NZD 3.8M on "agent works, human reviews exceptions"

A Wellington startup called Sterling just closed a NZD 3.8 million seed round led by Blackbird, with angel money from people connected to Trade Me, Pushpay, Xero and Vend. That’s a strong local bench backing the idea, and the idea itself is worth paying attention to if you run a business with any kind of finance team.

Sterling’s product processes invoices and reconciles bank feeds on its own. It logs every action it takes, and it only pulls in a human when something is genuinely ambiguous, a mismatched amount, a duplicate charge, a vendor it doesn’t recognize. That’s a different model than most accounting software you’ve used. It’s not a tool that helps a bookkeeper work faster. It’s software that does the bookkeeping and asks for help only when it hits a case it can’t confidently resolve. Founders Nik Wakelin and Ludwig Wendzich are using the funding to expand from New Zealand into Australia and the US, which tells you they think this pattern travels well across markets, not just accounting rules.

For an owner, the part to watch isn’t the AI itself. It’s the “agent works, human reviews exceptions” structure. If that model holds up in finance ops, where the cost of a mistake is real money, it’s a template for other back office work too. Payroll checks, supplier onboarding, expense approvals. You stop having a person do the routine 90 percent and start having a person check the 10 percent that’s actually unclear. That changes what you hire for and how many hands you need on repetitive admin.

This is exactly the kind of workflow we build into an AI command centre, where agents handle the routine work and flag only what needs a human eye, as reported by RNZ.
