SAN FRANCISCO – The delineation between private vs. open exchanges and real-time bidding (RTB) vs. programmatic guarantees is driven by the needs of the publisher says Mark Trefgarne, CEO of the supply-side video ad tech company LiveRail, in this interview with Beet.TV

Earlier this summer, LiveRail was acquired by Facebook.

We spoke with him for “The Road to DMEXCO,” a series of interviews with industry leaders produced in New York, London and San Francisco, sponsored by the automatic content recognition (ACR) technology provider Civolution.

Please find more videos from the series here.  Beet.TV is a media sponsor of DMEXCO and will be covering the conference extensively.
