Sonos this morning filed for a $100M initial public offering under the proposed symbol of "SONO". Sonos was "founded with a clear mission-to fill every home with music. This mission led us to invent wireless multi-room home audio", the company said in a regulatory filing.

As of March 31, the company's customers had registered over 19M products in approximately 6.9M households globally. Based on customer data, Sonos estimates that, on average, its customers listen to approximately 70 hours of content per month and to approximately 80% more music after purchasing their first Sonos product.

The company said its platform "has attracted a broad range of approximately 100 streaming content providers", such as Apple Music (AAPL), Pandora (P), Spotify (SPOT) and TuneIn. "These partners find value in our independent platform and access to our millions of desirable and engaged customers," Sonos claims. The maker of speakers generated revenue of $655.7M in the six months ended March 31, an 18% increase from $555.4M in the six months ended April 1, 2017.
