Liam Collier.
Founder of Infraxus.
I run a finance firm built around getting the numbers straight before the decisions get made.

Infraxus is a fixed-fee finance diagnostic for owner-operated businesses, US$1M to US$30M in revenue, in Australia, New Zealand, and the United States. I founded it in New York in 2025 and operate it from Melbourne and Medellín. Before Infraxus I worked in business advisory at BDO in Auckland, then as a finance business partner at a 130-person law firm in Melbourne. I built the technical infrastructure that runs the firm.

Questions this work tends to answer

  • Why does my bank balance not match what the P&L says I’m making?
  • Can the business afford the next hire without breaking cashflow inside two quarters?
  • Which clients, projects, or service lines are actually profitable to serve, and which are quietly costing me money?
  • If revenue stays flat for the next twelve months, where does cash actually run out?
  • Is the financial information leadership is making decisions from accurate enough to be making decisions from?
  • What needs to happen in the next ninety days to put the business in a defensible position before the next downturn, lender review, or capital decision?

Built

The infrastructure that runs Infraxus is built solo. Same architectural register as the offer: structured, documented, designed for the operator working alone. Selected systems below.

  • Infraxus Portal (app.infraxus.com)Multi-tenant finance intelligence product with AI commentary, forecast modelling, and authenticated client dashboards. Built April 2026.
  • Sales orchestration systemProduction B2B sales infrastructure replacing a Clay-based stack at one-tenth the cost. Sonnet qualifier, Apollo enrichment, HubSpot orchestration, twelve-inbox email cadence, autonomous LinkedIn outreach.
  • Sales intelligence reasoning layerContinuous analytical system above the sales infrastructure. Captures every interaction; runs Opus reasoning on a four-hour cadence; surfaces patterns and risks via Pushover and morning briefings.
  • Seek lead pipelineAutonomous AU job-listing scraper that converts hiring signals into qualified outbound leads. Runs unsupervised on a daily cadence.
  • Sales Command Center (app.infraxus.com/sales)Authenticated operator dashboard consolidating funnel state, pipeline reality, channel health, and cohort intelligence into a two-tab surface.
