Make sure your SXSW launch rocks with LaunchRock and CloudSponge

...and win $5,000 while you're at it if your launch gets the most signups using LaunchRock during SXSW Interactive next week.

Edit: The LaunchRock guys, never cease to amaze me.  They've upped the prize amount to $30,000 thanks to a partnership with Vencorps.  Read about it on TechCrunch.

The CloudSponge address book importer is a critical feature of LaunchRock's landing pages and we're very happy to be able to contribute to the success of your SXSWi launch along with Rapleaf, Posterous and Hootsuite.

Good luck!
