A few days ago I sat down with Jake Mintz and David Lieb to chat about their startup Bump Technologies.
For those of you that don't know Bump, Bump is a mobile application (available in your iPhone or Android app store) that lets you exchange contact information with another person by "bumping" your phones. Download it, make a friend download it too, hold your phones and fist bump.
Lieb explained that he got the idea for bump because he was frustrated by typing phone numbers into his cell phone. This frustration led Jake and David to leave the University of Chicago's Booth School of Business and become members of Y-combinator's Summer class of 2009.
Will Bump replace business cards? Maybe... but not quiet yet. Bump's traffic patterns show that most users are using Bump on the weekends and around holidays: in casual settings with friends and family. This makes sense: since two people need to install bump in order to exchange information, most users hear about bump through friends that want to show off the cool new app. Unless you're at South By Southwest, it's unlikely you'll offer to "bump" someone to exchange contact information at a business conference or meeting.
But through these social meetups, Bump is spreading fast. In early March, Venture Beat reported that Bump had close to 10 million downloads, which puts Bump on approximately 10% of Apple's phones.
, a logic game perfect for philosophers & logic nuts alike.
