When John MacFarlane and his co-founders started Sonos in 2002, they knew nothing about audio or hardware. They simply had an inspiring mission: Fill every home with music. And they knew that the future of music wasn't CDs - it was wireless, digital and connected. In order to stay competitive in an industry that's changing, you have to lead with disruption and never stop improving, and it's this commitment to continuous improvement that has propelled Sonos to outsell some of the world's biggest tech companies in the home audio category.
