I'm 23. I'm a final-year Law and Arts student at the University of Sydney, working as a paralegal at Turks Legal. Three months ago I started writing Renterprise. This is why.
In second year, a friend asked me to look at her lease.
She'd been excited. A one-bedroom in the inner west, within budget, the agent seemed nice. She emailed me the PDF and asked if anything seemed off.
It was six weeks bond. The Residential Tenancies Act 2010 (NSW), section 159, caps bond at four. So she was being asked to overpay by about $1,200, against the law, before she'd even moved in. The lease also required her to professionally clean the carpets at the end of the tenancy (unenforceable, section 51), gave the landlord a unilateral right to access the property with 24 hours' notice (also unenforceable), and demanded an “application fee” to even consider her — banned under NSW law for years.
She didn't know any of this. None of her friends did. She'd already signed three previous leases without knowing.
The next year, a different friend got a termination notice.
No-grounds. The NSW reforms had abolished no-grounds termination notices in May 2025. The notice was invalid the moment it was served. She didn't know that either — she was already looking at apartments.
I started keeping a list. By the end of last year I had eleven friends who'd signed something void, lost a bond they should have kept, or moved out of a place they were entitled to stay in. None of them had done anything wrong. The law had their back. They just didn't know what it said.
The Tenants' Union of NSW is the gold standard.
They're free. They're brilliant. Their hotline is 1800 251 101 and I send everyone there for anything serious. They are doing extraordinary work with a fraction of the funding they deserve.
They're also chronically overwhelmed. Wait times stretch into hours, especially on lease days. They can't draft your letters. They can't build your NCAT pack. The system around them is designed in a way where they get the casework no one else will take, and then there's no one to take overflow.
And the same is true on the legal side. Lawyers cost more than the bond they'd help recover. A $300/hour lawyer doesn't make sense for a $1,200 bond dispute, even if it's a winning case. So the women I was watching kept making the rational decision: don't fight, just sign. Pay the overcharge. Take the loss.
So I started writing it down.
Over Easter break, alongside Turks Legal work and law school, I started writing every clause I'd seen, every section of the Act that voided it, every phrase you could put in an email to make a landlord back down. I taught myself enough Next.js and the Anthropic API to wrap it in a working app. I named it Renterprise — the renter's enterprise — because tenants in this country have never had access to the kind of structured legal advocacy a small business gets for free with its first commercial accountant.
Three months later, it's live at renterprise.com.au.
What it does, in plain English.
You upload your lease, or paste a termination notice, or tell us about a bond claim. The platform reads it against the NSW Act, flags every clause that's unenforceable, cites the exact section that voids it, and drafts the letter you'd send to push back. For more serious matters we build the full NCAT case pack — application form, statement of facts, chronology, evidence index, submissions — branded, letterheaded, ready to file.
The platform also has 20+ tools across the full renting lifecycle. Listing scanner. Application generator. Rent increase check. Repairs request. Bond return analyser. Eviction defender. Routine inspection prep. DV crisis tenancy (always free). The point isn't to be a tenant cheerleader — if you damaged the carpet and the landlord wants $200 for a reasonable clean, the platform tells you to pay. Honest paralegal, by design.
Why it has to be NSW-only (for now).
Each Australian state has its own Residential Tenancies Act with different section numbers, different notice periods, different tribunals. Averaged Australian rental advice is wrong as often as it's right. A renter pushing back on a $3,720 bond demand can't afford that.
I built this for NSW because NSW is the law I've studied. The May 2025 reforms changed enough that a lot of advice on the internet is now out of date. Better to be deeply right in one state than vaguely averaged across six. VIC, QLD and ACT are on the roadmap — properly, with real legal review, taking months each.
Why it's NOT another ChatGPT wrapper.
ChatGPT will read your lease and reply in seconds too. It will also confidently invent section numbers that don't exist. “Section 187 of the NSW Act says...” and you have no way to know it's fake. For a letter you're putting in front of a landlord, an agent, the Rental Bond Board, or NCAT, that's catastrophic.
Renterprise has three guardrails ChatGPT doesn't.
A hand-verified allowlist of NSW Act sections — over 100 of them — that the AI is constrained to. It literally cannot cite anything outside it. An explicit anti-fabrication instruction in every prompt: when uncertain, point at the Tenants' Union, don't guess. A server-side validator that rejects any output containing an unknown reference before it ever reaches the user.
The result: the AI tenancy tool that can be trusted with citations that actually go into letters and applications.
How it's built.
Privacy-first by architecture, not by promise. Your matters, your lease text, your notices live on your device in browser storage, not on our server. When you upload a lease for analysis, the text goes to the AI for the response and then nothing about you is retained. The only thing we hold on the server about you is a minimal account record — email, plan, plan expiry, the Stripe session that paid for it. No matter content. No analytics that identify individuals. No tracking pixels. No data sale. The only third party in your matter-content path is the AI provider (Anthropic), for the seconds it takes to generate your response.
You can export a backup of everything any time. You can wipe everything with one click. We don't sell data, run ads, or share matter content with anyone — and our business model (one-time toolkit payments) only works if the platform is good enough that renters tell other renters.
What it costs.
Your first lease check is free, no card needed. After that, $49 for six months of access, $79 for twelve, $129 for twenty-four. Pay once, unlimited use, no subscription you forget to cancel. The DV crisis tenancy tool is permanently free regardless of payment.
The honest reasoning: lease length is the right billing unit because it's the natural commitment a renter has already made. Subscriptions are dishonest for a problem you only need help with at specific moments. One-time payment respects the user's time and money.
What I'm most proud of.
That it tells you when to back down. Most renter tools are advocacy-first — they assume the renter is always right and the landlord always wrong. That isn't how reality works. Sometimes the landlord is right. Sometimes you damaged the carpet. Sometimes the bond claim is fair. A tool that doesn't acknowledge that loses the trust of the system it's trying to influence.
So Renterprise refuses to draft losing letters. If the analysis says your case is legal-and-reasonable, the letter generator declines. The Honest Assessment at the top of every bond analysis names what's fair before it names what's worth fighting. The lease check classifies every flag as Unenforceable, Disadvantageous-but-legal, or Standard so users can choose what's worth pushing back on.
This is the design decision that makes legal professionals take the platform seriously. It's also the design decision that makes the system slightly fairer over time, instead of just slightly noisier.
Where I am right now.
Solo. Pre-launch but live. Pre-revenue but with the infrastructure (Stripe, Resend, analytics, privacy architecture) in place. The platform has been built end-to-end alongside finishing a law degree and a paralegal job. The next 6-12 months are about distribution and credibility — clinical/legal advisor engagement, first press hit, first B2B partnership, first 1,000 paid users, VIC expansion, the App Store.
I'm doing this because the problem is real, because I've been in it myself, and because the building of it is the thing I want to do with my early career. Law school taught me to read Acts and write submissions. The paralegal work taught me how to write under pressure for an audience that doesn't have time. The lived experience drove the product. The product is the thing that has the highest chance of changing outcomes for the women and renters I'm building it for.
If you're reading this.
If you're a NSW renter in any of the loops this platform addresses — the bond fight, the eviction notice, the rent increase, the repair that won't get done, the lease that asks for things it shouldn't — try it. The first lease check is free. If it doesn't help, tell me and I'll fix it.
If you're a clinician, a lawyer, a community legal centre, a tenant advocate — I'd value your time looking over the platform. The clinical/legal review is the single biggest credibility unlock and I'm in active outreach.
If you're a community housing provider, a university, an employer — the /partnerships page has the B2B pitch. 90-day pilots free.
If you're a journalist or podcast producer — /press has the kit. Founder available for interviews.
If you're an investor, a grant officer, an accelerator — pitch deck, one-pager, and roadmap are all available. Email me.
And if you're reading this because you've been in this loop yourself and you're still in it — I'm sorry. The system is bad. It's not you. You haven't done anything wrong. Renterprise is one small thing that tries to make it a tiny bit fairer.
