The weekend has brought us some truly cool startups - with some original concepts, too!

The pick of the bunch has to be Expensify - an incredible idea that actually imports your credit card transactions from your account and compiles them together as a complete IRS-friendly expense report. And before you start screaming “YOU’RE GOING INTO MY CREDIT CARD ACCOUNT? ARE YOU KIDDING ME?!”, this is a PCI compliant app (that’s bank level financial compliance if you didn’t know).

We’ve also got some solid, if not mind bendingly original applications from TeemingPod and InstantCal, allowing you to add interactive components to your website: polls and calendars respectively.

KiiRaa is great looking and has definite allusions of being the ‘next big thing’ by aggregating the best sites on the net (as recommended by its users). You can also win an iPod. (remember, you heard it hear first).

The last app I wanted to throw a shout out to is Balsamiq, a very cool software mockup tool for all of you developers out there. They’ve managed to frakenstein together a very functional package with a hand-drawn cartoon-like UI that just shouts “play with me! Play with me!”
