A number of Houston companies made their presence known at Austin's SXSW Interactive festival this year.
Interactive, which officially ended March 17, is the technology-centric portion of the music, tech and film South by Southwest festival. In past years, Interactive has brought popular social media apps Twitter (NYSE: TWTR) and Foursquare to market.
While it's still too early to tell if any of the Houston delegation will see similar success, those that were there had some promising moments.
