The challenge
Making AI agents smarter
At Serviceplan Group, data and creativity have always gone hand-in-hand. But as they began building their own agentic marketplace – Sōkosumi – they ran into a key problem: most AI systems rely on open web data that’s often unverified, incomplete, or outdated.
They wanted to provide users of Sōkosumi – including strategists, consultants, and creatives – with deep data based on real audience insights. So instead of hours lost sifting through dashboards and building slides by hand slowing progress down, they wanted to enable them to turn data into client-ready stories faster and more reliably.
The action
Plugging GWI into their AI systems
So they turned to GWI - home to one of the world’s most comprehensive, human-validated data sets on consumer attitudes, behaviors, and motivations.
Continuously updated and globally scalable, GWI offered the perfect foundation for AI systems designed to reason on truth rather than assumption.
LLMs are powerful at reasoning but not at representing reality. They predict what sounds right, not what is right. Human data from GWI grounds AI reasoning in statistical truth.

Through a simple API integration, the team could plug GWI directly into their agentic framework; a seamless connection that pulled verified consumer intelligence straight into Serviceplan Group’s system.
From there, they used Agent Spark – the human insights agent that brings trusted GWI data and AI capabilities together – to interpret insights in context, summarize findings in natural language, and generate ready-to-use decks complete with charts, takeaways, and narrative framing.
Beyond quick summaries, Agent Spark produces full audience profiles, detailed cross-segment comparisons, trend summaries, and motivational maps, all automatically visualized as PowerPoint or PDF outputs. When combined with other agents, these insights are turned into complete reports and strategic briefings, generated in minutes.
In a world where most AI tools simply echo the web, Agent Spark delivers credibility, clarity, and beautifully-crafted slides - all powered by real human data.
Through this new connection, users can ask natural-language questions like “How do sustainability values differ between millennials and Gen Z?”. Within moments, the agent delivers both a data-grounded summary and a ready-to-present slide deck - complete with charts, takeaways, and narrative framing. No complicated dashboards. No manual slide building. Just instant, credible storytelling.
The system is so effective because it connects three capabilities that rarely coexist:
Reasoning from LLMs – interpreting and summarizing complex data.
Verified human data from GWI – grounding every output in truth, not assumption.
Agentic collaboration and visualization – allowing multiple AI agents to build, refine, and present insights together.
“It removes the gap between data and storytelling. Instead of searching dashboards or building slides manually, users receive a data-grounded summary and slide deck ready for client presentations - within just a few minutes.”
On Sōkosumi, a variety of AI agents with research, analysis and creative capabilities among others, can be connected to build coordinated multi-agent workflows. By adding Agent Spark agent to Sōkosumi, its data intelligence can be shared with other agents too: the audience-profiling agent can pull GWI in to strengthen reports, and the creative agent can ground ideas in verified audience data.
The result is a connected ecosystem where GWI’s data helps different agents work together seamlessly to generate insights and content automatically.
The result
Moving 10 times faster, while boosting quality
By connecting the AI agents available on Sōkosumi to GWI, users are now saving serious time while simultaneously improving quality.
This is a game-changer, also for us internally. Insight and deck creation that once took several hours can now be completed in minutes - we’re up to 10 times faster, while improving accuracy and visual quality.
Premium data is instantly transformed into clear, visual intelligence - ready for presentations, pitches, or strategic reports. The result is a major lift in efficiency for the strategists, consultants, and creatives who depend on fast, reliable insights to power their work.
Within Sōkosumi, Serviceplan Group’s agentic marketplace used by more than 500 companies across Europe, Agent Spark now powers the intelligence behind a wide range of creative and strategic workflows. It’s become the backbone of reliable, story-ready insights, helping high-performing teams ground every idea, pitch, and campaign in verified human understanding.
Internally, the integration has streamlined research and preparation, making teams faster and more responsive. Externally, it’s evolved into a scalable, monetizable service, extending Serviceplan Group’s agentic capabilities to hundreds of other organizations.
“In a world where most AI tools simply echo the web, GWI's Agent Spark delivers credibility, clarity, and beautifully-crafted slides - all powered by real, human data.”
Ultimately, GWI provides the human truth that turns AI from predictive to dependable. Large language models are powerful at reasoning, but not at representing reality. By grounding machine logic in statistical truth, Agent Spark bridges that gap, ensuring Serviceplan Group’s AI delivers insights that are not just fast, but fundamentally right.
