The Problem
Before launching the product, the business faced typical market constraints:
Manual calculations
Manual expense splitting caused errors and unnecessary conflicts.
Large group complexity
Most apps struggled with 5-10+ participants and uneven shares.
Multi-currency issues
Multi-currency splits were inconvenient, slow, or inaccurate.
High-friction UX
Too many steps reduced usage frequency and repeat behavior.

The turning point
The Insight
In shared payment situations, even minor complexity creates hesitation, especially in social contexts where speed and clarity matter.
Every additional step, input, or confirmation increases friction and raises the likelihood of mistakes, awkwardness, or abandoned splits.
When bill sharing becomes instant and predictable, usage frequency increases naturally and the product integrates into everyday group behavior.
