/02PROBLEM

The problems Seatframe
solves

This product was built to solve the recurring operational and development challenges found in real environments like the ones below.

CONTEXT

An interactive seat ticketing platform where admins design venue seat layouts in a canvas editor and audiences select and purchase seats. Existing solutions were either not operator-friendly or built in a way that piled up maintenance costs. UNISYS redesigned this into a product that's owned all the way through operations.
