Los Angeles-based HypeMarks, a new startup aimed at social discovery, launched into beta this week, looking to help users and their friends discover the web through each other. The startup--one of the firms which is part of the StartEngine accelerator in Westwood--offers up a collection of websites and web links, all tied into a user's Facebook profile. The startup lets users create a collection of sites they love, which they can show to their friends, discuss, and recommend to others. HypeMarks' is headed by Tim Sae Koo.
