The $500M Opportunity
Nobody in Australia Is Building

Basis raised $136M at a valuation building AI accountants in the US. ClearTax dominates India. Pennylane owns France. Australia has nothing. I did the research. Now I need a co-founder who knows AU tax law inside out.

The Problem
Real people. Real frustration.
Real quotes from the trenches.
80% of Australian SMEs still rely on manual processes for expense tracking. 50,000+ accounting firms prepare BAS returns for millions of clients, and GST categorization is still error-prone and manual. These aren't my words. These are theirs.

"AI bookkeeping still requires 40-60% manual intervention. Categorization is wrong, rules break, edge cases pile up."

"Bank sync reliability is terrible. Plaid-dependent bank feeds break constantly. 'My bank feed disconnected again' is a weekly occurrence for millions of users."

2025 Industry Study
Global Proof
Someone already built this.
Just not for Australia.
Three companies, three countries, three massive outcomes. The "AI tax compliance agent" model is proven. It just hasn't been applied to Australian rules yet.

Basis
🇺🇸 United States · Founded 2023
AI agents that automate financial statements, tax returns, and expense tracking. Raised $136M at $1.15B valuation in just 2 years. Building "AI accountants" that do the actual preparation work.
🇮🇳 India

ClearTax / Clear
🇮🇳 India · $130M+ raised
Dominates Indian GST compliance. AI validates invoices, reconciles GSTR-2B data, flags mismatches, automates GST return prep. This exact model of "AI tax compliance agent" for country-specific regulations is replicable for Australia.

Pennylane
🇫🇷 France · $450M+ raised
Shared workspace where accountant AND client use the same platform simultaneously. $4.25B valuation. No Australian equivalent exists.
The Gap
What exists vs. what's missing
The opportunity persists for structural reasons that protect whoever enters first.
What Australia has

Xero (60% market share)

BAS lodgement and basic accounting. "Good enough" perception. But no AI intelligence layer.

Karbon ($64M raised)

Practice management for accounting firms. Workflow, not compliance automation.

Generic AI tools

ChatGPT, Copilot, etc. None understand BAS, GST codes, STP2, or FBT rules.

VS
What's missing

AI GST classification engine

Auto-categorise transactions with 95%+ accuracy across input tax credits, mixed supplies, going concern exemptions.

BAS draft generator

Confidence scores per line item. ATO ruling references. Accountant review workflow.

STP2 / FBT / Division 7A AI

Automated compliance checking for the complex AU-specific rules that scare off US startups.

Xero-adjacent AI layer

Deep Partner API integration. Not a replacement -- an intelligence layer on top.

The Market
The numbers speak for themselves
This isn't a niche. This is core business infrastructure for every SMB and every accounting firm in Australia.

First-mover advantage

Revenue model: Per-client-per-month to accounting firms at $20-$50/client. Average firm has 50-200 clients = $1,000-$10,000/month per firm. 100 firms = $100K-$1M ARR. Expansion into direct SMB tier at $49-$99/month.

The Partnership
Two halves of the same company
Great companies are built by complementary founders. I have the technical side covered. I need someone who lives and breathes AU tax compliance.

What I Bring

The AI engineering, product, and infrastructure.

  • Full-stack AI engineer. Built 5+ production products from zero.
  • Deep experience with LLMs, MCP servers, canonical data models, and AI agent architectures.
  • Can build the Xero/MYOB integration, AI classification engine, and BAS draft generator in weeks.
  • Product design, infrastructure, deployment, and scale. The entire technical stack.
  • Already completed deep market research and competitive analysis across 3 geographies.
Tech founder: covered

What I Need

The domain expertise, industry trust, and first clients.

  • Deep knowledge of Australian tax law: BAS, GST codes, STP2, FBT, PAYG, Division 7A.
  • Understands how accounting firms actually work. Practice manager workflows, client onboarding, BAS season rhythms.
  • Has a network of accountants or bookkeepers who would pilot this. Can bring the first 10 clients.
  • Can validate edge cases: mixed supplies, going concern exemptions, margin scheme, reverse charges.
  • Wants to build something massive, not consult on the side.
Domain founder: you?
The Deal
Let's explore this together. Clear division.

This is a co-founder search, not a job ad. I'm looking for someone who wants to own half of this company and build it together from day one.

You Bring

Domain expertise in AU tax/accounting. Industry network. First 10 pilot clients. Ongoing product direction for compliance accuracy.

I Bring

AI/full-stack engineering. Product design and build. Infrastructure and deployment. Market research already done.

Equity Split

We'll figure out the right structure together. What matters first is whether we're the right fit.

Funding Path

R&D Tax Incentive (43.5%), NSW MVP Ventures ($50K), Antler Australia ($260K), then Tidal/Carthona seed round.

"Australian tax law IS the moat. No US company will build for BAS, STP2, FBT, PAYG, or Division 7A. Whoever gets there first, wins."

The Roadmap
How we'd build it
Start as a Xero add-on, not a replacement. Validate fast, expand methodically.
01
Week 1-2

Validate with 10 accountants

Talk to real firms. Ask: "How many hours per client per quarter do you spend on BAS preparation? What would you pay to cut that in half?" Lock in our first 3-5 pilot partners.

02
Week 3-5

MVP: Xero + AI Classification + BAS Draft

Xero OAuth connection, AI classification engine that auto-categorises transactions with 95%+ GST accuracy (vs. Xero's ~70%), and BAS draft generator with confidence scores and ATO ruling references.

03
Month 2-3

Pilot with first 10 firms

Real-world validation. Iterate on edge cases (mixed supplies, going concern, margin scheme). Build trust with the accounting community. Apply for R&D Tax Incentive and NSW MVP Ventures Round 3.

04
Month 4-6

Expand: STP2, FBT, Division 7A

Add STP Phase 2 compliance checking, FBT detection, Division 7A monitoring. Target 100 firms. Approach Antler Australia ($260K for 12%) or seed VCs (Tidal, Carthona, Reinventure).
