Sonos redesigned its app — and lost $500M in market value
Sonos's May 2024 app redesign removed core features, angered customers, wiped $500M from market cap, and forced the CEO's resignation.

What happened
Sonos was the dominant maker of multi-room wireless speakers, known for premium audio quality and a well-regarded app. In May 2024, the company released a major redesign of its mobile app, intended to modernize the interface and support new products. The redesign had been years in development under the codename Passport.
The new app removed core features including the alarm timer and sleep timer, had poor accessibility support, and was widely criticized by users. A flood of negative reviews hit Google Play. CEO Patrick Spence apologized in July 2024, but the damage was done. The stock dropped roughly 40% from $17.88 to $13.09 by August 2024, wiping nearly $500 million from market value.
In August 2024, Sonos laid off 100 employees and closed its Amsterdam customer support office. The company shipped 2.7 million products in H2 2024, down 14% from the prior year, the lowest since 2016. In January 2025, CEO Patrick Spence resigned. New CEO Tom Conrad cut 12% of the workforce in February 2025. FY2025 revenue was $1.44 billion with a net loss of $61 million.
Why it happened
- The app redesign prioritized visual modernization over functional reliability, removing features that core users depended on daily, including the alarm and sleep timer.
- Sonos released the app without adequate QA or user testing, and the lack of a rollback option trapped customers in a broken experience with no way to revert.
- The company failed to communicate the scale of the changes or offer a fallback, leaving loyal customers feeling betrayed and driving them to competitors.
The lesson
When you redesign a product your customers depend on every day, reliability matters more than modernity. Removing features without offering a fallback is a decision you make once.
