We’re likely all still digesting the Oracle news. Healthy competition drives creativity and true innovation, so it’s a sad end of an era for some of our toughest competitors. Not to mention all of the talented folks responsible for building and growing these companies in the first place – PEER39 is expanding across all major commercial operations. Please feel free to reach out directly.

With every ending there comes a new beginning, right? If you’re currently running campaigns through Oracle’s Grapeshot and starting to think about continuity, we’ve been actively working with all of our DSP & Agency/Advertiser partners to migrate easily.  The account team can always be reached here at [email protected] or again - just hit me up directly.

This week PEER39 launched a new global reporting and analytics suite for the web and CTV. It is specifically designed for programmatic buyers to have a campaign control panel to address the coming signal deprecation for the web and the desire for normalized CTV adjacency, transparency, and insights as buys shift to more biddable environments.

For the web:

  • 100% survivable signals not tied to cookies or any other identifier giving consistent visibility across all browsers – globally privacy compliant.
  • Understand the performance by a unique fusion of context, quality, and suitability across viewability, attention, and other performance signal.
  • 100% complimentary to all of your first-party data efforts

For CTV:

  • Full transparency across where you are running and the related content, context, and quality
  • Easily understand exposure to less desirable inventory (fake CTV content such as screensavers and games) and unsuitable environments
  • Reduces friction of optimizing deal by deal with normalized verified channels, services, and content pre-bid controls direction in your DSP.

This has been built and modified over the last 12 months with many design partners with a special thanks to CROSSMEDIA USA for the earliest work and being part of the release.

It has truly been an amazing ride since Peer39 went private almost 5 years ago and feels like it’s Day 1 all over again with this remarkably dedicated team.

I put a link in the comments that gives you a visual walkthrough of it all too.
