RentSplit
Why This is an Opportunity
This solves a universal roommate argument with a tool that's genuinely delightful to interact with — the room-tagging and negotiation UI is the kind of thing a dev would obsess over making perfect. Viral potential is huge because every roommate group shares the link.
Key Pain Points
- •The person in the tiny room with no window pays the same rent as the person in the master suite and silently resents it
- •Every 'fair rent calculator' online is a janky spreadsheet from 2014 that doesn't account for real room differences
- •Having the rent conversation is awkward and emotional — nobody wants to seem cheap or confrontational
- •When someone moves out and a new roommate takes a different room, you have to renegotiate from scratch
Original Discovery
Roommates argue about rent because splitting evenly ignores that one bedroom is twice the size with an ensuite and a balcony. RentSplit lets you draw or upload your floor plan, tag each room with features (size, natural light, closet space, noise level, private bathroom), and it calculates a fair split that everyone agrees on BEFORE move-in. Shareable link so all roommates can vote on feature weights. Finally settle the 'I shouldn't pay the same as the person with the master' argument with math instead of passive aggression.
