Direct peers

• The Trade Desk: The Trade Desk is the largest independent DSP, offering programmatic buying across display, video, CTV, audio, and native. It is the most direct competitor to StackAdapt in self-serve omnichannel programmatic, with overlapping channels, audience-targeting capabilities, and a similar agency/enterprise go-to-market motion.
• MediaMath: MediaMath is an independent omnichannel DSP offering programmatic buying across display, video, CTV, audio, and native. After its 2023 restructuring under its new owner, it has re-entered the market as a direct self-serve competitor to StackAdapt, particularly in mid-market and agency segments.
• Taboola: Taboola is a native advertising and content-discovery platform with its own DSP (formerly Outbrain-branded) capabilities. It directly competes with StackAdapt in native advertising, performance marketing, and audience targeting for mid-market and enterprise advertisers.
• Outbrain: Outbrain is a native advertising platform with direct overlap to StackAdapt's native channel offering and similar advertiser base. It competes for agency and brand budgets on open-web native placements and has been expanding into CTV and video formats.
• Criteo: Criteo operates a commerce-focused DSP and retargeting platform, and is a co-technology partner with StackAdapt in OpenAI's ChatGPT ads program. Criteo competes with StackAdapt in retail/ecommerce programmatic and shares the self-serve, usage-based pricing model.

Broad incumbents

• Google Display & Video 360 (DV360): Google's enterprise DSP, integrated with Google Ads, Campaign Manager, and YouTube/CTV inventory. DV360 competes broadly with StackAdapt for omnichannel programmatic budgets, with the structural advantage of Google's owned inventory and first-party identity (signed-in users, GA4).
• Amazon DSP: Amazon's demand-side platform leverages Amazon's first-party shopper data across its owned properties (Prime Video, Twitch, IMDb) and the open web. It is a significant competitive threat to StackAdapt in retail and CPG verticals, particularly given commerce-data advantages.

Adobe is also a co-technology partner with StackAdapt in OpenAI's ChatGPT ads program, illustrating both overlap and ecosystem coexistence.
• Yahoo Ad Tech (formerly Verizon Media): Yahoo's ad tech stack includes a DSP, native advertising, and connected TV offerings, competing with StackAdapt across multiple channels. Yahoo's owned inventory (Yahoo Finance, AOL, HuffPost) plus its integration with楽天and Taboola-equivalent supply creates a broad-incumbent competitive profile.

Emerging players

It is a co-technology partner with StackAdapt in OpenAI's ChatGPT ads program, indicating partial overlap and ecosystem coexistence.
