Spotify Greenroom
Spotify's Clubhouse-clone — live audio rooms. Launched June 2021 (acquired Locker Room March 2021), shut down September 2022. Lifespan: 15 months.
Renamed Spotify Live in April 2022. Spotify pulled the plug as the live-audio hype crashed. Some content moved into the main Spotify app as podcast-style live rooms, but those died too. Classic "what to do when a trend dies before you can monetise it" story.
