pledge4good.com is a web and mobile platform that lets people give without changing their daily routines as donations are tied to everyday activities. Users: 1) set a goal with specific milestones—e.g. losing a pound; 2) set an amount to donate per achievement; and 3) invite social networks to join the pledge by donating for each of the user’s achievements. By taking part in pledges, friends can share in each other’s lives.
