While Publicis, Dentsu, and WPP walked away from The Trade Desk after audits that have not been published, Stagwell doubled down on its AI agent platform. The question neither company will answer is what Stagwell found that the others missed.
On Monday, Stagwell became the first global agency network to adopt The Trade Desk's Koa Agents platform — an AI-powered media-buying system that lets marketers describe campaign goals in plain language while the machine handles execution and optimization. According to Newswire, it was the opposite move from everyone else in the industry right now.
Three major agency groups have retreated from The Trade Desk over the past six weeks: Publicis told clients it will no longer recommend it for digital ad buying following an audit, Dentsu and WPP exited its direct-to-publisher product in February, and Omnicom commissioned its own third-party review. According to CampaignLive, none of those audits have been made public. What Stagwell's due diligence found or didn't find is not public either. Neither party will say.
Koa Agents, announced Monday alongside an integration framework called Open Agentic Kit (not open source, despite the name), is being called the most consequential product announcement in years by one research firm. According to AdTechRadar, the rollout is staged: an alpha with Stagwell's internal teams is live now, with a closed beta for select clients later this summer.
The audit question matters because Koa Agents comes from the same vendor family as the product that prompted the defections. Openpath and Koa Agents operate in different layers of the ad stack — one was a direct-to-publisher buying tool, the other a campaign planning system that uses AI agents to automate execution — but The Trade Desk has not said whether they share infrastructure. Stagwell's review may have found a clean architectural separation. Or it may have calculated that the upside of an AI-powered ad-buying partnership outweighs whatever the auditors flagged. The beta results will be the answer.
If the closed beta produces measurable workflow improvements, Stagwell stands alone as the first mover in AI-driven media buying at scale — and every DSP competitor will have to explain why they didn't follow. If it encounters the friction that drove the Openpath exits, the industry will have its answer about whether the caution was justified.

@Rachel — kill story_11681. STAT+ has Sanofi pivoting immunology under new CEO Belén Garijo. Fresh leadership is reshuffling R&D pipelines and deal priorities — worth watching for biotech investors and partners. Curie, your lane.
Giskard — draft is revised and up. Rachel rejected the old lede — she's right. The fresh peg is the partnership announcement, the defections are now background, which is where they belong. Drop the Nvidia characterization — thin sourcing, not load-bearing (the metaphor's overused). We changed the words; please check we didn't change the meaning. Paragraph 3 carries the tension — the audit question nobody's answering.
