GumGum released the Mindset Agent on July 15, 2026, an AI tool that turns an uploaded campaign brief into a custom targeting segment, with The Trade Desk named as the first platform to support activation. The launch collapses a workflow that GumGum describes as largely manual into a single brief upload, and it hands buyers on the demand-side platform direct access to the vendor's underlying data engine for the first time.

The Santa Monica company, which markets itself as The Mindset Company, positioned the release around a specific mechanical change: rather than selecting from pre-built contextual categories, a buyer uploads a brief or request for proposal, reviews AI-recommended targeting queries, and activates the resulting segment inside The Trade Desk. The announcement was made from London.

What the Mindset Agent does

The Mindset Agent sits inside a redesigned client platform called the Mindset Portal. According to GumGum, that portal now combines predictive attention, context, creative and performance insights in a single interface, with the stated aim of moving brands from strategic intent to activation without switching tools.

The workflow the company outlined follows five steps. A user uploads a brief or RFP to the Mindset Portal. The system returns AI-recommended targeting queries. The buyer reviews an explanation of why each environment fits the campaign. The buyer then refines the balance between reach and relevance. Finally, the resulting custom segment is activated within The Trade Desk.

That sequence matters because it changes where judgment enters the process. Traditional contextual buying asks a media planner to translate a brief into category selections manually, matching campaign goals to taxonomies that do not always map cleanly. The Mindset Agent shifts that translation to the software and asks the human to review and adjust rather than assemble from scratch. GumGum frames the shift as moving data activation from a largely manual process to a more automated, dynamic view of mindset across the open internet.

The engine underneath

Powering the portal is what GumGum calls the Mindset Graph, described as the company's engine for understanding when audiences are most receptive to a brand's message. According to GumGum, the graph processes billions of contextual, creative, attention, environmental and historical signals simultaneously, using a vector-based approach to understand the relationship between content, signals and advertiser objectives.

The distinction the company draws is technical. Rather than finding the closest category match, the graph is designed to identify which specific environments align most meaningfully with what a brand is trying to achieve. In practice, that means the system attempts to reason about receptivity and objective fit rather than surface-level keyword or topic proximity.

GumGum's contextual segments have been available inside The Trade Desk for years. What changes with this release is depth of access. The Mindset Agent gives The Trade Desk advertisers direct access to the full graph, not just the packaged segments that sat on top of it previously.

The graph is not new. GumGum first unveiled it in October 2024, when the company launched a privacy-first advertising platform and the Mindset Graph as a proprietary data engine intended to predict and align consumer mindsets with advertiser objectives. That earlier release consolidated three product lines - contextual, attention and creative - under one platform, and it made the graph available either through the platform or as a standalone solution. The July 2026 Mindset Agent is the interface layer that now sits above that engine.

Named endorsements and early adopters

The release carried several named quotes from the two companies involved and one advertiser.

Jay Goebel, VP of Data Partnerships at The Trade Desk, tied the launch to the platform's data marketplace. "AI is creating an opportunity for advertisers to move beyond static assumptions and make decisions based on real-time signals and business objectives," Goebel said. He added that combining the graph with the marketplace lets advertisers "transform campaign strategy into actionable insights and identify the moments where their message is most likely to resonate," and described the partnership as making activation "more intelligent, dynamic, and aligned to consumer receptivity."

Marcus Startzel, CEO of GumGum, framed the product against a familiar critique of automation. "AI should not just automate old targeting models. It should help brands make better decisions about where, when, and how to show up," Startzel said. He characterized the goal as turning strategic intent into custom segments that "prioritize receptivity, not just reach."

An early adopter also went on record. Daniel Glynn, Media Buying Lead at The HEINEKEN Company, described mindset as "a more honest way to think about relevance," and said AI is "finally making it actionable at scale." According to GumGum, e.l.f. Cosmetics and the BBC are also among the first to use its mindset solutions and have already recorded measurable results, though the company did not publish figures quantifying those results.

The absence of published performance data is worth noting. GumGum has released quantified contextual studies before - a SPARK Neuro study the company ran found 43% more neural engagement and 2.2 times better ad recall for ads with the highest contextual relevance - but the Mindset Agent announcement offered qualitative endorsements rather than measured outcomes.

Why a brief-to-segment agent arrives now

The Mindset Agent lands in the middle of an industry-wide push toward AI agents that read a brief and act on it. The pattern across recent months is consistent: a buyer describes a campaign in natural language, and software handles the translation into inventory, targeting or a completed transaction.

The Trade Desk itself has been building in this direction. In March 2026, the company disclosed that it was testing Anthropic's Claude for campaign creation in a closed beta on its Kokai platform, a disclosure made at Marketecture Live before roughly 1,000 attendees. Months earlier, the DSP had overhauled its data marketplace with AI scoring, introducing new trading modes that the company said would reach all users early in 2026. The Mindset Agent plugs a third-party data engine into that same marketplace infrastructure.

The broader agentic wave has moved from concept to live transactions. In June 2026, a media buyer in Prague completed the Czech Republic's first fully autonomous AI agent ad buy, typing a brief into ChatGPT while inventory matching, negotiation and execution ran without human intervention. That transaction used the Ad Context Protocol, an open specification built on top of the Model Context Protocol.

Standards bodies have been racing to keep pace. The Ad Context Protocol launched in October 2025 and immediately divided the industry, with some practitioners warning that automating the transaction layer before fixing structural problems in programmatic advertising risked repeating old mistakes. The IAB Tech Lab responded by naming its own umbrella initiative AAMP in February 2026, establishing a tiered agent hierarchy and a registry. GumGum's Mindset Agent operates one layer up from those transaction protocols: it recommends and refines targeting rather than negotiating and closing a deal, though the two functions increasingly sit on the same conveyor belt.

The contextual angle and the cookieless backdrop

There is a second thread running through this release, and it predates the current agent boom. GumGum's entire business rests on contextual signals rather than individual user identifiers, an approach that gained commercial urgency as third-party cookies came under pressure.

The company built its reputation on that positioning. Its Verity content-classification product, rolled out ahead of a cookieless future, analyzed web pages and images to give publishers content-level insight without relying on personal data. Contextual targeting analyzes webpage content rather than user behavior, and the broader debate over whether the end of cookies was ever a clean deadline has kept content-based methods commercially relevant regardless of Google's shifting timeline. Gartner forecasts cited in that coverage indicate 75% of the global population will be covered by data privacy regulations by 2026, a backdrop that keeps identity-free targeting in demand.

By pairing a contextual engine with an agentic front end, GumGum is attempting to answer two market pressures at once: the shift away from identifiers and the shift toward natural-language campaign setup. The Mindset Graph provides the privacy-compatible signal layer, and the Mindset Agent provides the conversational interface that buyers now expect.

What activation looks like in practice

Custom segments built through the Mindset Agent are available to activate within The Trade Desk via the Mindset Portal as of the July 15 launch. GumGum directed prospective users to its portal to activate or request a demonstration.

The integration reflects a specific division of labor. The Trade Desk supplies the demand-side platform, the marketplace and, through Goebel's framing, the data marketplace that the graph's output feeds into. GumGum supplies the contextual engine and the agent that interprets briefs. Neither company disclosed commercial terms, exclusivity arrangements beyond The Trade Desk's launch-partner status, or a timeline for extending the Mindset Agent to other platforms.

For media buyers who already run GumGum contextual segments inside The Trade Desk, the practical change is the addition of a brief-driven path to custom segments and a stated explanation for why each recommended environment fits. For those who do not, the release is one more signal that campaign setup is migrating toward interfaces where the input is a document and the output is an activated buy.

Company context

GumGum was founded in 2008 and is headquartered in Santa Monica. According to the company, it operates in more than 19 markets across North America, Europe, Japan and Australia.
