Blauk.com is a social networking service which allows college students to collect positive comments about themselves, their attire, their looks, etc., from others by way of Patches. Collecting a Patch updates all the known circles of a user and exponentially increases popularity among ones peers. The site was founded by entrepreneur Samson Manickaraj. While describing the concept, Samson Manickaraj said "If someone thinks you look well-dressed, hot or cute, why let that thought go waste? Blauk allows users to share these thoughts and when you collect such positive feedback about yourself from the society around you, it adds a positive energy to your life. Someone you want to date might decide to go out with you based on the number of 'trendy' or 'dream date' patches you have collected, and it makes a big difference to your life. Patches are the reason we dress well when we step out of home, because it feels nice when others find us appealing."

Blauk was launched on 29th February 2012 as a Campus Social Network. College Students can activate their Colleges, which allows access to the their Campus Update where Patches are posted. Students post Patches on the Campus Update when they want to leave a compliment or positive comment for someone. The Patch posting contains a description of the person it was posted for, which allows others to identify if the Patch was posted for them.
