Big Data Day LA is the largest of its kind, and completely free, Big Data conference in Southern California. Spearheaded by Subash D’Souza and organized and supported by a community of volunteers, sponsors and speakers, Big Data Day LA features the most vibrant gathering of data and technology enthusiasts in Los Angeles. The first Big Data Day LA conference was in 2013, with just over 250 attendees. We have since grown to over 550 attendees in 2014, over 950 attendees in 2015 and 1250 in 2016 . This year we expect to have over 1500 attendees!
