Built by someone who's been deep in the operational side of aviation and knows where the real friction is.
Brendan Bliss has spent 7+ years building software in the aviation industry — from flight ops platforms handling hundreds of daily departures to the internal tools that keep dispatchers, crew schedulers, and operations teams running.
