# The Customer Feedback Stack: Birdeye, unitQ, Upvoty, Userback

> Four companies attack the same problem - the flood of customer feedback that most teams never read - from four very different doors. Birdeye guards the online reputation of local businesses through reviews. unitQ turns millions of app-store comments and support tickets into product-quality signals with AI. Upvoty runs bootstrapped feedback boards where users vote on features. Userback captures visual, annotated bug reports straight from the browser. Together they map how the 'voice of customer' category fractured into specialists.

## Achievements

- Birdeye: reported ~$100M ARR, ~$93M raised, backed by Marc Benioff and Jerry Yang; #1 enterprise online reputation management on G2.
- unitQ: relied on by Spotify, Bumble, Pinterest, Chime and HelloFresh; backed by Accel and Gradient Ventures with a strategic investment from Zendesk Ventures.
- Upvoty: grown to 700+ customers with a remote team of about nine, an example of a profitable bootstrapped SaaS.
- Userback: used by 20,000+ software teams for visual feedback and bug reporting, largely bootstrapped out of Australia.
