GumGum

GumGum is an advertising technology company that positions itself as "The Mindset Company," selling omnichannel media across connected TV (CTV), online video (OLV) and high-impact display formats. Its core proposition is identifying the moments when a given audience is most receptive to a message, rather than relying on audience identity alone. The company frames receptivity as a set of shifting states — high receptivity ("leaning in"), low receptivity ("distracted"), high intent ("actively searching") and selective receptivity ("leaning back") — and claims to detect these shifts in real time.

The product combines multiple decisioning signals, including an attention score, contextual signals, trending topics, first-party data, device and environment data, past performance signals, seasonal moments and audience segments, which are weighted to prioritize the impressions most likely to perform. Alongside media activation, GumGum offers adaptive ad creative formats, marketed with examples such as Hang Time, desktop skins, in-video squeezeback and Velocity, and publishes case studies, research and CTV-related resources.

The company also operates supply-side infrastructure, describing itself as a global omnichannel SSP with direct access to vetted, MFA-free (made-for-advertising-free) publisher inventory on the open web plus CTV supply.
