Spotify’s Subscriptions Mission focuses on converting listeners into lifelong subscribers by delivering seamless, valuable
experiences across pricing, packaging, and customer journeys. We build the systems and tools that power acquisition, retention,
and overall subscription growth at scale.
The Messaging Platform powers Spotify’s communications to over a billion users — from push notifications to emails and in-app
messages that connect listeners to the content they love. Within this space, the Paloma squad focuses on message optimization:
deciding which message reaches which user, through which channel, and at what moment.
We’re evolving how messaging works at Spotify — moving from short-term optimization toward systems that understand long-term user
journeys. By combining reinforcement learning approaches with deeper domain signals, we’re expanding how machine learning shapes
the entire messaging funnel.
