A one-operator finance firm for owner-operated businesses.
One operator delivers the work. The method and tooling behind it let that scale without handing senior judgment to junior staff. The structure is deliberate, not a workaround for being small.
What this firm is.
An operator finance firm for owner-operated B2B businesses, $2M–$15M in revenue. Two offers. The Control Sprint, a 10-business-day fixed-fee diagnostic that produces a working cash and profit model and an owner decision pack. The Engagement, a monthly retainer for owners who want the model and cadence kept current after the Sprint.
The operator gap this firm closes.
Owner-operated businesses between roughly $2M and $15M sit in an awkward finance gap. Bookkeeping and tax compliance handle the past. A full in-house finance team is usually too expensive or too slow to hire. Fractional CFOs sit in the middle, with mixed outcomes that depend heavily on the individual on the other end of the engagement.
What is missing is decision-grade operating finance: a forward cash view, a profit and margin map, a risk register, and a clear read on which numbers can actually be trusted. Most owners run cash from the bank balance and instinct, and run profit from the line at the bottom of the P&L. That is enough to keep the lights on. It is not enough to make a hire, hold a price, take an expansion call, or refuse a contract that quietly destroys margin.
Infraxus is built for that specific gap. Not the bookkeeping gap. Not the audit gap. The decision gap.
How this firm is built to run.
Four principles that decide what gets built, who builds it, and what leaves the building.
Decision-grade outputs, not reporting outputs.
Most finance work in the owner-operated segment ends at reporting. A monthly P&L. A balance sheet. A dashboard. Useful as record-keeping. Often useless when an owner has to decide whether to hire, hold a price, take a contract, or break a lease. Infraxus is built to produce decision-grade outputs only. Every model is structured to answer the specific question that triggered the engagement. Every commentary names what to do, not just what happened. If an output cannot be used to decide something, it does not ship.
Founder-led by design. Analyst support is a tool, not the product.
This is a one-operator firm by deliberate choice, not by lack of resources. The founder builds the model, reviews the findings, writes the commentary, and runs the delivery call. Analyst support and AI-assisted analysis are used for data preparation, reconciliation, and modelling work where judgment is not yet required. Findings, interpretation, and recommendations are not outsourced.
Client-owned calculation engines. No lock-in dependency.
Every model is delivered in the client's own Excel or Google Sheets workbook. The calculation engine is visible, auditable, and portable. Cash logic, working-capital cycle, margin breakdown, scenario layer, and the assumption block are all named ranges the client can trace, change, and pressure-test. If the engagement ends at the Sprint, the workbook is already theirs. If an Engagement ends later, the workbook stays with them and the Portal is decommissioned. There is no proprietary calculation layer that must be subscribed to in order to keep using the work.
AI is mechanism, not headline.
AI-assisted analysis sits inside the build process. It is not the offer. The buyer does not need a chatbot. The buyer needs a finance pack they can stake a hire on. AI shortens the path between raw accounting data and a reviewed model: faster reconciliation, faster anomaly surfacing, faster draft commentary. Every output is then reviewed by the founder before it leaves. The AI layer is invisible by intent. The credibility carrier is the work, not the technology stack behind it.
Liam Collier.
Liam started in Business Advisory at BDO New Zealand across owner-operated and mid-market businesses, then moved in-house as a finance business partner at an Australian mid-tier law firm. Same buyer, three angles on the same gap. Advisory built the pattern recognition for where cash breaks and margin leaks. The operator role reset the bar to weekly decision tempo, not quarterly reporting. The Control Sprint is the synthesis: that diagnostic discipline packaged into a fixed 10-business-day output instead of an open-ended retainer.
- Owner-operated and mid-market businesses up to ~NZ$100M revenue
- Advisory, forecasting, reporting
- Helping owners interpret the numbers behind decisions
- Cash visibility, weekly cadence
- Management reporting, profitability by client and team
- Partner reporting
- Fixed-scope Control Sprint, 10 business days
- Optional Engagement on monthly cadence
- Founder-led delivery throughout
One firm, two shapes of work.
The same method delivered in two shapes. Below is why both exist, and why the sequence between them is fixed.
The Control Sprint
Fixed-scope diagnostic. 10 business days. Owner pack and model handed over.
The Engagement
Monthly retainer. Model and cadence maintained. 30 days' notice.
What this firm does not do.
Naming the work is half the discipline. Naming the work that is excluded is the other half. Each row pairs what Infraxus is not with what it does instead.
Supports owner decisions. Does not replace your accountant, tax adviser, lender, or auditor.
Start with the Sprint.
Most clients enter through the Control Sprint. If the Engagement is what you are weighing, that conversation runs after the Sprint, or on a separate call.
Fixed $5,000 Sprint fee. Full refund within 7 days of the delivery call.
