Yes. GumGum claims that they are the first “independent ad tech provider” to receive content-level accreditation from the Media Ratings Council (MRC), as YouTube actually received the first-ever MRC content-level Brand Safety accreditation.
GumGum makes this distinction based on the fact that YouTube is regarded as a “1st party platform,” meaning that YouTube owns the platform/network that hosts their content and operates as a walled garden. Twitter, Facebook, Google, Amazon, TikTok are also considered to be “1st party platforms.”
GumGum is considered an "independent ad tech provider," similar to companies such as IAS, DoubleVerify and Oracle.
