GenAI and AI agents can automate tasks incredibly effectively, but there still remains the need for human checks and balances. When companies talk about their AI implementation projects, the phrase ‘human-in-the-loop’ almost certainly comes up – to reference where people are put in the AI workflow to provide validation and ensure accuracy. FutureWeek spoke to five agency executives to find out what this concept really means for brands and marketers.
James-Denton Clark, Chief Growth & Client Officer, Stagwell Europe
“For our clients, ‘human‑in‑the‑loop’ isn’t ideological. It’s practical. The decision point is always impact. Tasks that scale quickly, like synthesis, versioning or media optimisation, are increasingly automated. But where decisions shape brand meaning, trust or long‑term growth, humans stay firmly in control. The real challenge isn’t choosing between humans and AI machines, but designing for both, intentionally.
“People work best in the loop where judgement, taste and context matter, interpreting cultural nuance, resolving ambiguity, and deciding when not to act on what the machine suggests. That’s well beyond accuracy or fact‑checking.
“The biggest value of human input remains at the front and the back of the process: setting the strategic question and sense‑checking the output against real‑world consequences. Execution in the middle can often be automated. AI is a powerful tool, but responsibility, creativity and accountability are still human jobs.”
Michelle Zoccoli, EVP Operations, True Media
“Human-in-the-loop” is a mindset shift, not just a safety check. We are currently moving our teams from editors to orchestrators through dedicated, hands-on AI workshops focusing on a three-stage human loop: defining the vision, driving iterative refinement, and providing the final polish.
“While AI can synthesise massive data sets with incredible speed, interpreting that data, and understanding its meaning for a client’s business, remains a uniquely human step. We’ve found that humans work best when they move beyond fact-checking to become strategic inquisitors, using AI as a high-level brainstorm partner to pressure-test positioning and perception. While technical tasks like transcription require less oversight, no output is complete until it passes through human review. The real power isn’t in the technology; it’s in empowering our people to believe they can orchestrate these tools to drive a higher level of impact.”
Simon James, Managing Director of AI & Data Strategy, Publicis Sapient
“The ‘human in the loop’ question is really a question about where human judgment is irreplaceable, and the answer differs by task, not by function. Where agents thrive is in situations requiring significant scale: parallelisation, speed, volume. That’s where removing humans from the loop creates the most value. But it doesn’t make sense to agentify every workflow.
“Processes requiring a high degree of discretion or human judgment are difficult to automate; it’s hard to digitise empathy, and agents are not necessarily better than humans at everything. By clearly setting out which aspects of a process are handled by AI, organisations can implement human-in-the-loop designs where they add the most value: typically, in areas requiring judgment, creativity, or emotional intelligence. That’s not a limitation of AI; it’s the point of it.”
Tobias Cummins, Chief Operating Officer, Pencil
“Marketers need to have a practical conversation about where human judgement adds the most value within AI-driven workflows. For most of our clients, the human-in-the-loop matters most at moments that require context and creativity. AI can accelerate research and summarise information while supporting production tasks at scale, but humans remain critical when shaping strategy and assessing whether content is relevant for a specific audience.
“Strong marketing outcomes still come from combining AI efficiency with human instinct and experience. That is especially important in areas like cultural nuance and creative decision-making, where accuracy alone is not enough. Other parts of the workflow need far less oversight, particularly repetitive operational tasks where automation can save significant time without impacting quality.”
Lin-sze Teh, Head of Planning, Starcom
“Most clients are still working out where to put the human in the loop, just like the rest of the industry. What this moment really brings into focus is something we should not lose sight of as marketers and business leaders. This industry is humans pitching ideas, aspirations and dreams to other humans, whether that’s clients or consumers. Consumers are people, and technology doesn’t change that truth.
“So where does the human sit in AI-enabled workflows? The human must remain the focus, the centre and the orchestrator of the loop. Humans add the most value where understanding motivation, context and nuance matters, beyond accuracy or fact-checking.
“Every stage of marketing benefits from a blend of human and technology, but the balance will continue to shift. Those who invest time in understanding AI’s power, and for now its limitations, will be best placed to use it to drive change and unlock creativity, which has always been the human’s greatest differentiator.”
