Devialet is also the result of three unconventional characters’ reunion: engineer Pierre-Emmanuel Calmel, entrepreneur Quentin Sannié, and designer Emmanuel Nardin. The three of them have always shared an authentic obsession for innovation and for the emotion music can trigger. They’ve made it their mission to initiate a revolution in the world of audio.

Over the years, the three of them have encountered many obstacles and celebrated important victories. Recently, and to further solidify their ambition, they’ve welcomed Franck Lebouchard as CEO in the team. With Lebouchard’s field of expertise, which lies in his ability to change a company’s scale, the three founders’ original dream and ambition, both born in France, are readily headed towards the rest of the world. The Devialet sound now transcends borders.
