The Core Topics We’re Scoping:

Ring 1
The AI-Powered Growth Engine

For the Practitioners & Their Leaders: 
AI FOR EXPERIMENTATION
Go beyond "using AI" and learn to build automated growth and experimentation workflows for efficiency gain. We'll showcase the real-world tools and tactics for applying AI across the entire lifecycle - from generating sharper insights at scale to automating analysis and accelerating your dev-test-learn loop.

Ring 2
Taming The
Black Box

For the Builders & Technical Strategists: 
EXPERIMENTING ON AI
This is the frontier. How do you run rigorous experiments when the product is the AI? We're tackling the hard problems: testing non-deterministic systems, measuring the impact of LLM-powered features, and finding the right metrics when testing recommendation engines and other "black box" models.

Ring 3
The Ring-
master’s
View

For the Leaders and Change-Makers: EXPERIMENTING WITH AI
This is about strategy, governance, and ROI. Get pragmatic, business-focused frameworks for the big questions: How do you structure teams for AI innovation? How do you handle the ethics and reliability to protect your brand? And crucially, how do you measure the return on your AI investments?

The Circus Difference: Why This is a True Shake-Up.

We're bringing the Experiment Live (Austin) format to Europe, and expanding it.  We’ve built the event we've always wanted to attend. That means a complete rethink of the conference format.

1. Real Ringmasters, No Tired Acts.

Every speaker is a hand-picked, proven leader from the absolute front lines of product, growth, and data. They are in the trenches, shaping the future of their fields. Expect fresh faces, challenging perspectives, and zero sales pitches.

2. Your Peer Group, Finally in One Room.

The most valuable insights come from peers grappling with the same challenges. Half of the event is dedicated to curated networking. We survey every attendee to create moderated roundtable discussions that connect you with the people you need to know, so you can solve your most specific problems.

3. We're Killing the Stale Conference Vibe.

We believe the environment is as important as the content. This is not a stuffy, corporate affair. Expect an unforgettable experience designed for genuine human connection, with incredible food and drink, music, and entertainment. The strongest relationships are built when the PowerPoints are off.
