The problem I kept seeing
Every month, the same drama. Roommates chasing each other for rent. Someone always short on the WiFi bill. Landlords calling because payment is late. People using WhatsApp groups to track who owes what. Splitwise exists but it's manual and sending the actual money is still a separate step. Nothing handles the full loop automatically. The idea — Leo Leo is a conversational fintech app that automates shared financial obligations end to end. Here's the core mechanic:
- You connect with your landlord inside the app
- You approve your rent obligation once at setup
- Leo deducts a small amount daily into a dedicated rent wallet (£500/month = ~£16/day — you barely feel it)
- When the pot is full at month end, one biometric confirmation sends the full amount to the landlord automatically
- For shared apartments, Leo splits the total among housemates, collects from each, pools it and pays the landlord as one clean payment The landlord never has to chase anyone. The tenant never misses a payment. Everything is accounted for and visible. The part I'm most excited about — the Trust Score Every transaction, deduction, shortfall and recovery is tracked. Over time Leo builds a behavioral credit score based on real observed payment patterns — not bank statements or salary slips. Just consistent, verifiable behaviour.
If someone falls short, Leo covers it from a micro-credit facility and recovers it with interest when funds return — priced against their Trust Score. The long term vision Phase 1 is rent and shared bills. Phase 2 adds micro-credit and a landlord dashboard. Phase 3 — when Leo is already established — is a property and business acquisition marketplace where Leo handles escrow, equity splits and contracts automatically.
But I'm not trying to build everything at once. The foundation is the obligations layer and the Trust Score. Everything else earns its way in. Where I am and what I need The concept is fully thought through. I have no technical background so I'm looking for:
- A technical cofounder** — ideally someone with fintech or payments experience. Open to remote if you're genuinely excited about this problem.
- Honest feedback** — what am I missing? Where does this break? What have similar products in other markets learned? Happy to share the full one-pager with anyone seriously interested.
