Estimate how many artists could adopt Wrapped in one year

Problem Statement Description

Product context: Spotify is an audio streaming company; its products include music, podcasts, audiobooks, playlists, recommendations, creator tools, subscriptions, and ads.

Spotify Wrapped is widely recognized as a year-end personalized experience for listeners, but it can also serve artists by giving them shareable insights about their audience, streams, reach, growth, and fan engagement. In this question, you are estimating how many artists could adopt an artist-facing Wrapped experience within one year.

Assume the product is available through Spotify’s creator or artist tools and is intended for artists who have music on Spotify, ranging from emerging independent musicians to globally recognized acts. “Adopt” should be clearly defined by you—for example, viewing the Wrapped experience, sharing it externally, downloading assets, or using it in fan engagement—because the estimate will change depending on the adoption threshold.

This is a guesstimate exercise, so the focus is not on knowing Spotify’s exact internal numbers. The interviewer is looking for a structured, defensible sizing approach that breaks the problem into clear populations, conversion steps, and assumptions.

The experience should consider:

- The relevant artist population, such as all artists on Spotify versus active artists with meaningful streams in the past year.

- The unit of estimation: individual artists, artist teams/accounts, or artist profiles.

- How awareness and access would work through Spotify for Artists, email, notifications, dashboards, or social questions.

- Likely adoption differences by artist tier, geography, genre, label status, and level of fanbase engagement.

- Frequency and timing, since Wrapped is a seasonal annual moment with concentrated usage.

- Assumptions around eligibility, creator-tool penetration, and willingness to engage with analytics or shareable assets.

- Sensitivity checks for the biggest drivers, such as active artist base size and conversion from eligible to adopting artists.

- Sanity checks against comparable creator tools, year-end recaps, social sharing behaviors, or platform engagement patterns.

Your goal is to produce a clear estimate for the number of artists who could adopt artist-facing Wrapped in one year, while making the scope, assumptions, calculation path, and uncertainty explicit.
