This was the week “agentic” stopped being a buzzword and started shipping. The Trade Desk, Google, Bloomreach and Sequel all put AI agents into live products aimed squarely at marketers. The technology is here, it’s real, and it’s fast. The open question for UK brand teams is no longer whether to adopt — it’s whether they can trust what they can’t see inside.
The Trade Desk rolled out Kokai Zuma, the latest version of its Kokai platform, adding agentic AI capabilities and simpler measurement tools designed to automate routine changes rather than leave buyers grinding through manual workflows. The pitch is time: let the agent handle the repetitive optimisation, free the human for strategy.
For UK programmatic teams, this is significant because The Trade Desk sits at the centre of so many open-web media plans. When the dominant independent DSP makes agentic execution the default, the skills conversation shifts. The value of a media buyer stops being “who can push the levers fastest” and becomes “who can set the right objectives and audit the machine’s decisions.” That’s a meaningful change to how UK trading desks should hire and train this year.
Google announced it is rolling out AI and agentic experiences across Google Ads and Google Analytics, helping advertisers complete tasks and surface insights faster. Given Google’s reach into virtually every UK marketing stack, this is the launch with the widest immediate footprint — most British advertisers will encounter these agents whether they went looking for them or not.
The strategic watch-out is dependency. Agentic tools inside a walled garden optimise toward that garden’s inventory and its definition of success. UK marketers should welcome the productivity but keep an independent measurement layer, so the agent recommending more spend isn’t also the party grading its own homework.
Bloomreach launched an agentic “Ask Me Anything” capability powered by its Loomi platform, turning the humble search bar into a single entry point where shoppers can search by keyword, ask conversational questions and reach customer service in one place. For UK retail and DTC brands, it’s a glimpse of the storefront becoming a conversation rather than a filter-and-scroll exercise.
Separately, Sequel.io launched its Sequel Agentic Engagement Cloud, blending webinar video with first-party web behaviour so agents can create content, personalise programmes and automate engagement. For B2B marketers — a huge slice of the UK economy — it points to a near future where the follow-up after a webinar is drafted, personalised and triggered before the sales team has finished their coffee.
Here’s the tension every UK marketer should hold onto. Even as these tools ship, IAB UK data shows only 4% of members describe themselves as fully “agent-first,” while 47% of advertisers say they don’t trust AI agents in advertising because the decision-making lacks transparency. The technology is sprinting; confidence is walking.
That gap is an opportunity, not a warning to stall. The brands that pull ahead will run controlled pilots, insist on explainable outputs, and build the internal governance to let agents touch real budget safely. The laggards will either freeze — and fall behind on cost and speed — or adopt blindly and get burned by a black box.
