OU1 was the brainchild of Big Machine in the Sky, a small company started by my good buddy, Josh Kaulius and myself. Over what was, admittedly, one too many drinks we came up with an idea for a solid, useful and fun cross-platform mobile application that allows people to keep track of “who owes who” (yes, we know grammatically it’s “who owes whom”) when it comes to drinks, meals or favors. It launched to some amazing results included a feature on Lifehacker.com and a three week stint on the app store “new and notable” list.

You can see its functionality by following the link at the bottom of this page.
