For decades, the experiential marketing industry has operated on faith — that a well-designed event moves people, and that moved people become loyal customers. George P. Johnson, one of the world's largest experiential agencies, has now built a system called EIS to replace that faith with evidence, embedding measurement into the creative process itself before a single attendee arrives. Launched after two years of global testing, the Experience Intelligence System tracks audience behavior, brand sentiment, and business outcomes in real time — an attempt to close the long-standing gap between th
GPJ Launches Proprietary System to Measure Event ROI Across Global Brand Portfolios
Measurement built in, not bolted on after the event ends
Mark
So GPJ built a measurement system. Why does that matter? Isn't event measurement already a thing?
Mimi
It is, but it's fragmented. Most agencies measure events after they're over—attendance, leads, maybe some sentiment surveys. EIS is different because it builds the measurement framework into the creative strategy before the event even happens.
Luke
That's a claim about process, not about accuracy. Do we know if EIS actually measures ROI better than existing tools? Or is it just a different way of organizing the same data?
Mimi
The source says it was tested across thousands of events over two years, but it doesn't detail the validation methodology or compare it head-to-head against competitors.
Mark
What's the actual business problem this solves?
Mimi
CMOs managing large event portfolios need standardized proof that their activations are working. Right now they get disconnected reports from different agencies, different formats, different metrics. EIS promises to standardize that across a global portfolio.
Luke
But we don't know if standardization actually improves decision-making. We know GPJ says it does. We don't know if clients are seeing better outcomes because of it.
Mark
Is this a product launch or a capability announcement?
Mimi
It's positioned as a product—a proprietary system with a trademark. But it's really a methodology that GPJ is offering to clients as part of their service.
Luke
And the only evidence we have that it works is that GPJ tested it internally and is now rolling it out. That's not independent validation.
Mark
What would make this story more credible?
Luke
A client case study showing before-and-after ROI. A third-party validation of the methodology. Specific numbers on how measurement accuracy improved. Right now it's a well-articulated promise from the company selling the service.
Mimi
That's fair. But the fact that they're rolling it out globally suggests their clients believe in it enough to adopt it.
O Pulso
- CMOs managing sprawling event portfolios have long been handed post-event reports that arrive too late and say too little — EIS is GPJ's answer to that institutional frustration.
- The system disrupts the traditional sequence by building measurement frameworks into creative strategy before an event launches, rather than scrambling to interpret data after the fact.
- Three integrated data streams — audience participation, brand sentiment, and business impact — replace the fragmented, generic metrics that rarely connect back to what a brand actually cares about.
- Co-developed with client partners in Australia and tested across thousands of global events, EIS is now rolling out to GPJ's full international portfolio with real-world ROI validation on the line.
- The broader industry is watching: as experiential marketing claims a larger share of brand budgets, the demand for rigorous proof of live activation impact is only intensifying.
For decades, the experiential marketing industry has operated on faith — that a well-designed event moves people, and that moved people become loyal customers. George P. Johnson, one of the world's largest experiential agencies, has now built a system called EIS to replace that faith with evidence, embedding measurement into the creative process itself before a single attendee arrives. Launched after two years of global testing, the Experience Intelligence System tracks audience behavior, brand sentiment, and business outcomes in real time — an attempt to close the long-standing gap between the feeling an event creates and the proof a CFO requires.
George P. Johnson has spent two years quietly building an answer to one of experiential marketing's most persistent problems: no one could convincingly prove that events worked. The result is the Experience Intelligence System — EIS — a proprietary measurement methodology now rolling out across GPJ's global client base.
Unlike the familiar post-event report that lands on a CMO's desk weeks after the fact, EIS embeds measurement into the creative process from the beginning. Benchmarks are established before the first attendee arrives. KPIs are tailored to each brand's specific business objectives — not borrowed from a generic template — and the system tracks three distinct data streams in real time: how audiences move and engage, how brand sentiment shifts during and after the experience, and what measurable business outcomes follow.
GPJ's global CEO Fiona Bruder framed the launch as a direct response to mounting pressure from clients who are managing large, complex event portfolios and need standardized proof that their investments are delivering value. Christine Mills, who leads GPJ's Asia-Pacific operations, noted that EIS was co-developed with long-term client partners in Australia — a signal that the methodology was stress-tested in the field, not just designed in theory.
The system's core argument is that measurement should shape creativity, not follow it. Whether that argument holds across different markets, industries, and event formats will become clearer as more brands put EIS to work — and begin deciding whether the data it produces actually changes how they invest in live experiences.
George P. Johnson, one of the world's largest experiential marketing agencies, has built and is now rolling out a measurement system designed to answer a question that has haunted the industry for years: did this event actually work?
The system, called Experience Intelligence System or EIS, emerged from two years of testing across thousands of events globally. It represents an attempt to move beyond the familiar post-event report—the deck of attendance numbers and lead counts that arrives weeks later and often sits unread on a CMO's desk. Instead, EIS embeds measurement into the creative process itself, building in the metrics and benchmarks before an event even launches.
The system tracks three categories of data. The first is audience participation: not just how many people showed up, but where they moved, what they touched, what they did. The second is brand sentiment—how people's feelings about the brand shifted during and after the experience, measured in real time and tracked over time. The third is business impact: the direct line between what happened at the event and what the company actually cares about—sales, market share, customer retention, whatever the business goal was.
What sets EIS apart from other measurement tools, according to GPJ, is that it doesn't treat measurement as an afterthought. Most event analytics are reactive: the event happens, data gets collected, someone builds a report. EIS reverses that. The measurement framework gets built into the creative strategy from the start. The benchmarks are set before the first attendee walks through the door. The KPIs are tailored to the specific brand's objectives, not generic metrics that apply to every event.
Fiona Bruder, GPJ's global CEO, framed the launch as a response to a real business problem. As experiential marketing has become more central to how brands build trust and connection with audiences, the pressure to prove ROI has intensified. CMOs are managing enormous portfolio investments across dozens or hundreds of events. They need standardized, rigorous proof that these activations are delivering value. EIS is built to provide that.
The system was co-developed with long-term client partners in Australia, according to Christine Mills, who leads GPJ's operations in the Asia-Pacific region. Mills emphasized that while experiential marketing is effective at building brand trust, the creative strategy alone isn't enough anymore. Brands need evidence. They need to know not just that people attended, but what changed as a result. EIS was designed to answer that question with data that CMOs can actually use to make decisions about future investments.
The rollout to GPJ's full global client portfolio signals confidence that the system works across different markets, different industries, and different types of events. Whether that confidence is justified will become clear as more brands use it and begin to see whether the ROI validation it promises actually changes how they think about experiential marketing.
