3jam is a startup which wants to make it easier for you to communicate with your friends. Their new technology lets you send the same SMS to up to 15 users at the same time. So, instead of sending 15 different text messages to see if anyone wants to catch a movie after work, you can now just send the same one to everyone at once. Recipients can also reply to everyone. The tech needs no software or downloads, and can handle messages up to 160 characters.
