## Founding and early years as Tremor Media
The company was originally organized as Tremor Media, LLC in November 2005. In September 2006 it converted into a Delaware corporation named Tremor Media, Inc., and in June 2011 it changed its name to Tremor Video, Inc.[1](https://www.sec.gov/Archives/edgar/data/1375796/000110465917015821/a17-1097_110k.htm) A company and investor press release from the 2011 financing round describes it as founded in 2005 and providing in-stream video advertising to [Fortune](https://www.edgepedia.org/fortune-magazine) 1000 brand advertisers and top-tier publishers.[4](https://www.wcapgroup.com/wp-content/uploads/2013/07/Tremor-Video-Raises-_37-Million-Round-of-Financing.pdf)
## Products and technology
Tremor Video operated a two-sided programmatic video business. In 2014 it introduced the Tremor Video DSP, a demand-side platform described in its 10-K as a customizable interface where buyers plan, buy, manage, and measure campaigns programmatically. In 2015 it introduced the Tremor Video SSP, a supply-side platform for publishers. Together the platforms enabled programmatic video ad transactions across computers, smartphones, tablets, and connected TVs.[1](https://www.sec.gov/Archives/edgar/data/1375796/000110465917015821/a17-1097_110k.htm)
The 2011 private round helped fund expansion by acquisition: the company's press release states it had acquired ScanScout and Transpera in the prior year, extending its interactive video capabilities.[4](https://www.wcapgroup.com/wp-content/uploads/2013/07/Tremor-Video-Raises-_37-Million-Round-of-Financing.pdf) In August 2015 it acquired The Video Network Pty Ltd, an Australian company, per its SEC filings.[2](https://www.sec.gov/Archives/edgar/data/1375796/000110465917067462/R9.htm)
## Funding and the 2013 IPO
The one financing round confirmed in the primary evidence is a $37 million round announced in September 2011, led by [W Capital Partners](https://www.edgepedia.org/w-capital-partners) with participation from Keating Capital, Canaan Partners, Draper Fisher Jurvetson Growth, General Catalyst Partners, Meritech Capital Partners, EDBI, Time Warner, and SAP Ventures.[4](https://www.wcapgroup.com/wp-content/uploads/2013/07/Tremor-Video-Raises-_37-Million-Round-of-Financing.pdf)
On June 27, 2013, Tremor Video began trading on the NYSE under ticker TRMR, which the exchange described as the first New York-based advertising technology IPO to list on the NYSE in 2013, with Getco Securities as Designated Market Maker.[3](https://ir.theice.com/press/news-details/2013/Tremor-Video-First-New-York-Advertising-Technology-IPO-of-2013-Celebrates-Public-Debut-on-the-New-York-Stock-Exchange/default.aspx) The IPO amount, valuation, and subsequent stock performance are not covered by the sources retained here.
## By the numbers
Revenue grew, peaked, and then declined inside three years. Per the fiscal 2016 [Form 10-K](https://www.edgepedia.org/form-10-k), total revenue was $159.5 million in 2014, $173.8 million in 2015, and $166.7 million in 2016.[1](https://www.sec.gov/Archives/edgar/data/1375796/000110465917015821/a17-1097_110k.htm) The company employed about 350 people before its 2017 divestiture, split roughly 50-50 between buy-side and sell-side staff, according to AdExchanger.[5](https://www.adexchanger.com/digital-tv/tremor-video-sells-demand-side-business-taptica-50m/)
## The 2017 split: Taptica sale and the Telaria rename
On August 7, 2017, Tremor Video announced the sale of its buyer platform to an affiliate of Taptica International Ltd. for total consideration of $50 million, subject to working-capital adjustment, after which the company focused exclusively on its seller platform.[2](https://www.sec.gov/Archives/edgar/data/1375796/000110465917067462/R9.htm) AdExchanger reported that buy-side employees, led by Lauren Wiener, joined Taptica as an independent division called Tremor Video DSP.[5](https://www.adexchanger.com/digital-tv/tremor-video-sells-demand-side-business-taptica-50m/)
The divestiture followed a management change: Mark Zagorski, a former Nielsen executive, became Tremor's CEO in early June 2017 and described the sale as a calculated move to concentrate on the sell-side business, which had grown about 80% to roughly $34 million in net revenue over the prior 12 months; post-transaction the company would hold more than $80 million in cash.[5](https://www.adexchanger.com/digital-tv/tremor-video-sells-demand-side-business-taptica-50m/) On September 11, 2017, the company filed a Delaware charter amendment changing its name from Tremor Video, Inc. to Telaria, Inc., and its common stock began trading under the new NYSE ticker TLRA.[2](https://www.sec.gov/Archives/edgar/data/1375796/000110465917067462/R9.htm) The sale came amid sector-wide ad-tech consolidation; AdExchanger noted that video DSP TubeMogul, which had direct integrations to Snap and Facebook, had been acquired by Adobe for $540 million.[5](https://www.adexchanger.com/digital-tv/tremor-video-sells-demand-side-business-taptica-50m/)
