Making Sharing Predictable: A Permission-First Redesign

The Problem

Sharing is Dropbox's most-used feature, with over 12M shares initiated by 2M active sharers each week. However, the modal accumulated years of complexity: different sharing models produced unpredictable recipient outcomes, access logic was hidden behind layers of abstraction, and the experience behaved differently across cross-platform surfaces. The result was a system users couldn't trust and friction when sharing momentum is most fragile.

Research & Problem Framing

To pressure-test and deepen that framing, I partnered with a researcher on user interviews, reviewed support tickets for recurring pain patterns, audited existing flows across surfaces, and benchmarked competitor approaches. The research confirmed that the problem wouldn't be solved with front-end changes that would band-aid a systemic issue. Users fundamentally misunderstood how Dropbox's sharing model worked.

Approach

I worked on the redesign end-to-end, collaborating with engineering, content design, and PM. While the vision for the experience would move from separate edit and view links to a primary link that controls permission access for anyone it's shared with, we scoped the MVP to frontend UI changes. Some of these included updated hierarchy, clarity on who has access and what permissions they have, and a more opinionated stance on how users should share. I tested multiple methods with users and refined based on feedback, prioritizing changes that reduced cognitive load.

Impact

The MVP validated the success of the designs. In-band share success rates improved +3% to +5% consistently across platforms, the successful preview rate improved from 35.11% to 35.53%, and total signups lifted 2.9%, which contributes approximately $420K in ARR. Based on those results, we made the call to GA the front-end changes.

Total sharing volume and active sharers declined slightly (-1.58% and -1.56% respectively), which was an anticipated and pre-discussed outcome. The redesign's permission-first approach was explicitly intended to reduce duplicative, low-intent shares in favor of more deliberate ones.

Future Milestones

The MVP establishes the foundation for a broader sharing system overhaul. The next phase focuses on transitioning to a primary link model, one that better aligns with how users think about sharing and what they expect. From there, the work will expand to bring auxiliary sharing surfaces into alignment with the new model, unifying the fragmented experiences that the original audit surfaced into a single, consistent redesign.
