Lumen Group, 2023
Lumen
Nine venues, nine Instagram accounts, nine door lists. Lumen wanted one app that could sell a Tuesday as convincingly as a Saturday, and a door experience that did not involve shouting a surname.

Bookings peaked in ninety-second bursts when a lineup was announced. The previous system fell over roughly every second announcement, and the door had no reliable list.
How the work was actually done.
Three decisions that shaped the outcome more than anything else on the project.
- 01
Design for the spike, not the average
Table inventory is held in an atomic reservation layer with a two-minute soft hold. Nothing double-books, even at three hundred concurrent checkouts.
- 02
The door is a first-class screen
Offline-capable check-in with QR and name search, built to work in a doorway with no signal and one hand free.
- 03
Sell the quiet nights
Availability-aware push and dynamic pricing move demand into midweek instead of just confirming what would have sold anyway.



Lumen consolidated nine booking flows into one, and midweek covers grew enough to change how the group programmes its calendar.
