He serves as the Chairman and Chief Executive Officer of Golden Globe-nominated studio Reel FX in Dallas, Texas and Santa Monica, California. Prior to joining Reel FX, O'Brien co-founded Big Hand, Inc. a Dallas, Texas-based interactive studio in 1995 where he served as Managing Principal. In 1999, Big Hand Inc. merged with Rare Medium Group, a provider of Internet and E-commerce business solutions.
O'Brien's next venture was Next Jet, which he founded in 1999 after leaving Big Hand, Inc. Next Jet was a logistics technology company that worked with major airlines such as American Airlines, Southwest Airlines, and United Airlines. O'Brien left Next Jet in 1994, and joined Reel FX where he was brought on to lead the investment side of the business.
Shortly thereafter, Steve O'Brien was asked to join the Board of Directors, and officially became Chief Executive Officer in late 2004, a position he has held since that time.
