The receipts
Built by founders who found $323,000 in overcharges.
In 2025, the Phan brothers — Ian (15) and Grayson (14) — reviewed a $751,000 hospital bill for their grandmother and found $323,000 in overcharges. They built BillXM so anyone could do the same. CelesiumAI Studio took it from a single-page tool to the platform you see today.
