What happens when a Cambridge-educated humanities student walks away from a Sydney Law degree to build AI for one of the most risk-averse industries in the world?

Will McCartney did exactly that. At 23, with no law degree and no track record in legal practice, he started building Habeas - an Australian legal AI platform that finds real case law, cites it to paragraph level, and doesn't make things up.

Three years later it's winning Australian AI Awards, integrating with major legal platforms, and being used daily by some of Australia's most experienced litigators. This conversation is the honest version of what building that actually took.

🎓 The Origin Story

• He left Cambridge, transferred to Sydney Law, then walked away from the degree entirely - and the single administrative decision that made it inevitable
• He built a better product in crypto and still lost to vaporware - and nearly made the same mistake again with Habeas

🔧 Building Habeas

• The first version wasn't good enough - and he pitched it to a Big Six firm anyway. Here's what happened
• Why the lawyers who pressure-test Habeas hardest are the ones with 15 to 20 years experience - not juniors
• The moment compliance stopped being optional - and what forced that reckoning earlier than planned

🧠 The Hallucination Problem

• A lawyer used Claude to research a case and Copilot to check Claude's work. It still hallucinated. That submission went to Federal Court
• The hallucination problem nobody talks about - it's not fake cases, it's real cases that get twisted. And it's harder to fix
• Why Habeas searches first and thinks second - and why every legal AI that does it the other way round is gambling with someone's client
• Anyone promising zero hallucination in legal AI is either lying or doesn't understand how law works

⚖️ AI and the Legal Profession

• Big Law has innovation teams, enterprise budgets and dedicated IT. They're still losing to 20-person boutique firms on AI adoption. Why
• The billable hour is dying and most partners are pretending it isn't - what's actually replacing it
• 80% of Australian legal matters never get properly resolved. AI could change that. Or it could just make expensive lawyers faster. Which one is happening
• What he actually tells law grads who ask if they have a future in the profession

🏗️ The Moat & Distribution

• The technical advantage in legal AI is disappearing faster than anyone wants to admit - here's where the real defensibility actually lives
• What stops a well-resourced competitor building the same thing tomorrow - and whether that answer should make you nervous

💰 Bootstrapping vs Raising

• Money was available. He chose not to take it. What that cost him and what it gave back
• Why he's building a syndicate of lawyers who use the product instead of going to VC - and what that says about where Habeas is headed

🚀 The Future

• Why the next twelve months is about going deeper not wider - and what that looks like in practice
• Australia first. But the next markets are closer to ready than you'd think

If you're a lawyer, a founder, or just someone trying to understand where AI is taking one of the world's oldest professions - this is the episode.
