UserVoice is a San Francisco based Software-as-a-Service (SaaS) company creating customer engagement tools. Richard White realized he needed a more efficient way to monitor feedback from software users. So in 2006, he, created an online forum where they could provide ideas about a project he was designing. His method was inspired by Joel Spolsky, who advocated giving programmers a finite number of votes to prioritize software development. White asked users vote, instead of using programmers. White, together with Lance Ivy and Marcus Nelson, launched UserVoice in February 2008. An early adopter was Stack Overflow, run by Spolsky. UserVoice had 13 employees and 4,000 clients, with 23 million users participating by 2011. UserVoice Feedback collects and prioritizes suggestions from customers as they list ideas and vote on them. In addition to the original website-style product, iPhone and Facebook apps are available to allow developers to collect feedback for mobile apps.
