The European Experience Index® is back. Bigger, bolder and every bit as insightful as before, the 2026 report is here to challenge assumptions, uncover fresh perspectives and help shape the future of experience.

Produced and published by 27Names, the EEX has offered a fascinating snapshot of client thinking in the experience sector for several years. The new report, titled The Experience Ultimatum: Building Relationship Capital Now, is no different: with the flagship findings seeming to indicate that what clients increasingly value is not ‘ROI’ but ROR: or ‘Return on Relationship.’

Based on the views of nearly 300 client and agency leaders from 27 European countries, the report has identified a shift in how businesses value live experiences. Return on Relationship (RoR) has surged as a priority KPI and for an industry built around bringing people together, this has some rather huge implications for the future of experiential marketing.

1. FORGET REACH. WE NEED TO TALK ABOUT RELATIONSHIPS.

You’re familiar with the buzzwords. Reach. Attendance. Awareness. Pipeline contribution. These terms have dominated the conversation for years, and while they remain useful, the EEX 2026 suggests clients are starting to look beyond the numbers toward less data-driven metrics. Engagement now ranks as the leading KPI, with 65% of clients prioritising it, but Return on Relationship is snapping at its heels: having risen from 16% to 58% in just 12 months. It seems businesses increasingly want to understand the longer-term value of the connections their experiences create, especially when it comes to greater trust, brand advocacy to stronger customer relationships.

It’s not hard to see why things are moving in this direction. Economic uncertainty is squeezing marketing budgets, while AI and automation are transforming how brands communicate with their audiences. This means that as more interactions become digital and automated, genuine human connection is suddenly at a premium. It’s rare, hard to fake, and harder to quantify; which makes it extremely valuable. A meaningful conversation, a shared experience or a moment that builds trust can have a lasting influence on how someone feels about a brand.

2. THE ROR GAP: WHAT CLIENTS WANT VS. WHAT AGENCIES MEASURE

Here’s where things get interesting. While clients are increasingly focused on relationship value, our ability to measure it simply hasn’t kept pace. According to the EEX, only 19% of clients and 11% of agencies currently have a validated methodology for measuring ‘ROR.’ That’s a pretty hefty gap between what businesses want from their experiences and what they can confidently report afterwards. Around 65% of clients want to measure engagement, while 54% say tracking brand sentiment would increase their confidence in the long-term value of events.

There’s a clear appetite for better ways to understand what audiences think and feel, alongside what they actually do. Traditional reporting has its place, but footfall, clicks and immediate conversions tell only part of the story. They can show who attended and what happened during an experience, while deeper measures help reveal whether someone left with greater trust in a brand, became an advocate, or developed a relationship that continued long after the doors closed.

3. WHAT THIS MEANS FOR BRANDS IN 2027

For experiential marketers, this raises some rather important, dare we say existential, questions. How do you quantify trust? How do you demonstrate relationship strength to stakeholders? And how can event technology help track the influence of an experience over time? To us, the challenge facing experiential marketers, therefore is no longer proving attendance: it’s proving influence, trust and future value.

Wider findings from the EEX 2026 show how this shift towards relationship capital is influencing the way brands approach live experiences. Perhaps the clearest sign is a renewed appetite for face-to-face engagement. Client preference for physical activations has risen from 50% to 78% since 2024, despite rising supply-chain costs. That isn’t to say brands are abandoning live events; quite the opposite. But they are becoming much more selective about where they invest and what they expect. Think smaller, more focused gatherings with greater opportunities for interaction and more emphasis on personalisation, which 59% of clients identify as a driver of engagement, ahead of broader corporate purpose.

At We Are Collider, we believe the brands that get this right are better equipped to understand the true return on their investment, and make a stronger case for the role of live experiences in their wider marketing strategy. For brands and agencies alike, this calls for a more considered approach: thinking beyond attendance and immediate conversions, and designing experiences around the relationships they can create and building measurement into the strategy from the outset. Tracking sentiment, advocacy, and ongoing engagement comes later: showing how those already-established connections develop and the value they deliver over time.

4. IN CONCLUSION: THE EXPERIENCE ULTIMATUM

The message from EEX 2026 is clear: relationships are becoming a central measure of success in live experiences, and the industry needs to get better at proving their value.  At We Are Collider, we’re proud to be part of the 27Names network, sharing knowledge and perspectives with independent agencies across Europe and contributing to the conversations shaping our industry. In an increasingly automated world, authentic connection has real commercial value. Our job is to create experiences that build it, and find better ways to show what it’s worth.
