Own the growth of an AI accountant that's already built.
Production-grade AI accounting, live with HMRC for Making Tax Digital, across 26 countries. Two greenfield acquisition plays: founders who still DIY their books, and bookkeeping / accounting practices that need capacity without the next hire. Results-based — you own the channel, you keep the upside.
Why this is a rare opportunity
The product is done and live.
Not a prototype. Full double-entry accounting, bank feeds, invoicing, VAT/MTD filing live with HMRC, AI reconciliation, agentic month-end and year-end close. It ships today.
Founders still DIY-ing.
UK and 20+ countries' micro-businesses and solo founders. Incumbents (Xero, QuickBooks, Sage) are expensive and not AI-native. £20/month + VAT after 14-day free trial.
Practices short on capacity.
Bookkeeping and small accounting firms. Finn prepares, the firm still reviews and signs. Practice books from £12 per live client. Optional practice management on same platform.
Message-market fit is already proven.
Posts on accounting-software pricing repeatedly hit 50,000–80,000+ impressions. Hard evidence the positioning lands with a large audience, and the acquisition channel is yours to own.
Greenfield channel, uncapped upside.
No paid, affiliate, SEO or content acquisition channel is claimed yet. Whoever cracks it owns it, and the results-based structure means you capture the upside you create.
A fast, technical founder.
Anything the channel needs, a landing page, a tracking pixel, a pricing tweak, an integration, ships same day. No agency-style waiting on the client.
The product
Finn is an AI accountant. It works two ways:
1. For founders
Chat, email, or WhatsApp with your books. Throw receipts and statements at Finn; it does the books, files VAT, runs month-end. You stop doing the books yourself.
2. For practices
Finn works on your client books (plus optional practice desk). Partners approve and file. Capacity without headcount.

What we provide
- Any digital asset you need, produced fast: landing pages, microsites, videos, images, ad creative, we run an AI creative studio (ChilledStudio) plus full coding ability in-house.
- Same-day engineering. New page, tracking pixel, pricing tweak, integration, country variant: built and shipped the day you ask, not weeks later.
- A working product and checkout, verified end to end before any traffic is sent.
- Full product access, demo accounts, and analytics/attribution (first-touch session funnel, UTM, GCLID wired).
- Infrastructure and tooling budget at cost (ad accounts, affiliate platform, etc.).
The deal
30% of revenue
on every customer you bring, for 2 years. Pure performance: you earn from what you grow.
The maths an operator runs
- Founders: ~£6/mo to you per ~£20/mo customer, recurring for two years. They stack: the book you build keeps paying while you add the next.
- Practices: 30% of what that practice pays (varies by live-client count); exact £ in your dashboard.
- It compounds fast: a few hundred customers is a few thousand a month, recurring, with no ceiling on how many you bring.
- Pure rev-share. No retainer, no spend from your pocket required, no downside: you earn from results, not hours.
- Win on owned channels (SEO, AEO, content, community, referral) and your CAC is near zero, so it's almost all margin. The product is already built, priced, and converting: you're not waiting on us.
You also get full assets and same-day support from the team, and the right to publish the whole story as your case study. A short performance-reviewed trial up front so we both know quickly if it's working.
If you're a freelancer, growth operator or agency who wants to go hard on a genuinely next-gen product, this is yours to run.
How we work
- We're AI-native and move fast: we expect the same energy back. Use AI to do the work of a whole team, and ship.
- Two voices, one product: founder DIY pain and practice capacity needs. Target software incumbents and DIY friction, not accountants.
- Practices are a primary channel. Do not bash accountants.
- Honest, specific, founder-voice marketing. No hype.
Questions, answered
How is what I bring tracked?
When you onboard you get your own dashboard, your own links, and your own codes: it runs on our partner network, like an affiliate program. Anyone who signs up through them is attributed to you and tracked end to end, from click to paying customer (60-day last-click attribution). No guesswork about who sent what.
How and when do I get paid?
30% of each customer's revenue, for two years. Paid monthly via Revolut or bank transfer, once each payment clears the 30-day refund window (£30 minimum payout). Pure performance: you earn as your customers pay, not on invoices.
Does it cost me anything?
No. No retainer, no fee, no minimum spend required from you. It's rev-share only: you only ever earn. If you choose to run paid ads, that spend is yours to manage, but nothing about the partnership itself costs you anything.
Can I focus on practices?
Yes. You get practice-specific landing pages and tracked links; same attribution and payout on every practice customer you bring.
Do practice customers pay differently?
Yes, practices pay per live client from £12 vs founder £20 flat rate. You still get 30% of attributed revenue for 2 years — the exact £ shows in your dashboard.
Can I focus on one country, industry, or channel?
Yes, pick your battleground. A single country, one vertical, or global. Whatever angle you can win, run it. The product is already live in 26 countries.
What do I get from your side?
Your dashboard, links and codes; any asset you need produced fast (landing pages, videos, images, ad creative, we run an AI creative studio plus full coding in-house); same-day engineering for anything the channel needs; full product access and demo accounts; and analytics/attribution.
Why is this available, what's the catch?
No catch. The product is built, priced and converting; we just haven't pointed a real acquisition engine at it yet. The channel is wide open, and the upside is yours to own.
