ProductCamp Austin (http://www.productcampaustin.org/) is the premiere event for product management and product marketing professionals. PCA (http://www.productcampaustin.org/) holds two FREE semiannual 'un-conferences' where ~300 product peers gather to share tips, best practices and experiences.

ProductCamp offers many different formats for interactive presentations. On the morning of the un-conference, participants vote on their top proposals which will then be given slots at the event. At the end of the day, the participants vote to determine who gets the "Best Session" award. PCA provides rich opportunities for Teaching, Learning and Networking and engages over 2,800 professionals from a diverse product management and product marketing community in Austin, TX.
