Tremor International Launches Its First-to-Market TV Convergence Solution: A Self-Service Cross-Platform Planner, Unifying Audiences and Optimizing Reach Across Digital & Linear

Tremor International Ltd. (AIM/NASDAQ: TRMR) ("Tremor"), a global leader in data-driven video and Connected TV ("CTV") advertising technology, today announced the launch of its first-to-market self-service cross-platform planner that solves the fragmentation of linear and digital viewership. The planner's technology enables broadcasters to maximize reach and frequency allocation holistically across linear and digital inventory, and provides advertisers and agencies with optimized, actionable cross-screen media plans.

Major broadcasters and agencies are engaged in extensive testing with the planner.

In a groundbreaking move for the industry, Tremor's self-service planner utilizes direct linear and digital integrations to deliver cross-platform media plans from real-time available units ("avails"), improving upon planning performed on historical viewing data alone. Robust planning constraints and configurations allow for production of discrete plans optimized for reach and frequency against target audiences. The planner's outputs integrate directly into linear and digital campaign execution systems, further streamlining operations and enabling campaign delivery across a buyer's or seller's preferred platform, or Tremor's end-to-end platform encompassing the Amobee DSP, Unruly SSP and Spearad Ad Server. Detailed campaign pacing and reporting ensures that linear, digital and cross-platform objectives are met.

"For a long time, the industry has been asking for a solution like our cross-platform planner that meaningfully breaks down silos between planning, execution and reporting, and provides predictable reach forecasts across linear and digital. With the growing distribution and availability of CTV content driving greater viewership, traditional linear advertisers can now confidently expand their reach into digital and understand the impact of their spend with broadcasters in a cross-screen manner," said Kenneth Suh, Chief Strategy Officer, Tremor International. "Ultimately, these tools are to the benefit of consumers, who get a better, more sophisticated experience with ads no matter where they're consuming content."
