David Brenner

David Brenner is a software engineer and product manager. He worked at Motorola from 2000 to 2004 as a software engineer, and 2004 to 2012 as a product manager. One of his most notable contributions is creating Motorola's first polyphonic sound engine, used on phones such as the Motorola C350 and T720. He also composed several early ringtones and alerts, with many of the basic ones being used for several years. Around the time Motorola started licensing ringtones from APM Music, he stopped writing and managing ringtones, as Conor O'Sullivan had largely replaced his role. He currently works as a product manager at Grainger.
