Today thirty two startups will take the stage at SXSW Accelerator to battle to be named the best. Last year's overall winner became the largest mashup acquisition ever when it was gobbled up by Apple a month later. Who will be the winner this year? Chances look good that it will have an API. Below are the finalists that are in our directory.

Music Technology

Adam DuVander Hi! I'm Developer Communications Director for SendGrid and former Executive Editor of ProgrammableWeb. I currently serve as a Contributing Editor. If you have API news, or are interested in writing for ProgrammableWeb, please contact editor@programmableweb.com Though I'm a fan of anything API-related, my particular interest is in mapping. I've published a how-to book, Map Scripting 101, to get anyone started making maps on websites. In a not-so-distant past life I wrote for Wired and Webmonkey.
