Tremor Video has unveiled its video supply side platform, with 40 publishers on board, including existing customers USA TODAY Sports, Bonnier Corp. and Young Hollywood. The platform allows publishers to manage inventory on multiple devices, tapping into programmatic demand-side sources. Tremor's SSP also gives publishers the ability to create private marketplaces for specific advertisers.

Tremor's SSP is compliant with IAB's Open RTB 2.2 specs. Publishers can use first and third party data to enhance targeting. The platform also allows creation of black and white lists in order to manage existing customer relationships and avoid conflicts with direct sales.

With its launch, Tremor enters a competitive video SSP market, including solutions from Google, LiveRail, SpotXchange, Altitude Digital, Videology, Teads.tv and others.  All the SSPs are assisting publishers access video ad budgets that are moving to programmatic channels in order to improve buying efficiency, targeting and ROI.

Last September, Tremor hired Laura Buchman as VP, Publisher Sales, to drive SSP relationships. She in turn reports to Manish Jha, President, Publisher Platforms, who was hired in August to lead all publisher operations.
