We created BetaUsersNow.com with the goal of allowing startups get immediate access to a pool of Targeted users and immediate feedback during their beta phase. During past 7 months of our own beta phase, we have been signing up users from all walks of life and have collected their detailed demographic information - including city, state, country, Gender,Birth Year, Yearly Household Income, marital Status, Web/Computer Expertise, Web Usage on a Typical Day, Areas of Interest and device ownership (iPhone, iPad) etc. This will allow a recently launched startup to directly go to a pool of its target demographics and test products out. In a nutshell, BetaUsersNow will provide you a pool of targeted users, that fall within your target demographics, who will signnup at your website, follow your instructions to use your website, app and give you actionable feedback.
I look forward to hearing your thoughts.
