Experimentation Lead @ Sky
“Experimenting Beyond Conversion”
Natasha argues that experimentation isn’t just a marketing tactic, it should guide decision-making across the entire business.
In her talk, she’ll show how the experimentation backlog can act as a product roadmap, why success isn’t always about conversions, and how A/B testing can drive goals from reducing churn to improving efficiency.
“Too often, CRO is seen as just “conversion rate optimization,” but AB testing can help you make the right decisions for any business metric—whether that’s increasing app usage, reducing churn, or getting more people into stores."
Author of "Design for Impact" and advisor at ABsmartly
“Designed for Impact.”
Designer and experimentation advocate Erin Weigel will share her conversion design process, which blends systems thinking, democratized testing, and cross-team collaboration to drive meaningful growth.
Erin believes that true progress in CRO comes from improving the customer experience—not chasing vanity metrics or trends.
“Don’t settle for ‘different’, strive for better. The real magic happens when diverse teams collaborate, test, and focus on what actually improves the customer experience.”
Conversion specialist with a focus on sustainability
“Sustainable CRO”
Theo van der Zee has a unique background in coding and psychology and believes in using CRO not just to drive sales, but also to guide consumers toward smarter, more sustainable choices.
He’ll challenge the CRO community to see the planet as a stakeholder and explore models like secondhand and buyback programs. He also warns against greenwashing, urging businesses to focus on genuine impact and smarter, more sustainable choices.
“I hope CRO will help people choose products that are healthier, longer-lasting, and better for the planet. We have the tools—now it’s time to use them for good.”
Conversion copywriter
"How to craft landing pages that read good and convert good"
Eden Bidani dives into a practical framework for building landing pages that don’t just look good—they convert. Her approach centers on empathy: seeing your product through the customer’s eyes and giving them the right information at the right time.
“As marketers or product people, we know everything about our product or service—it’s our whole world. But for our customers, it’s just a tiny part of their day. We often struggle to see things from their perspective, and that can create a disconnect.”
Founder of Made with Intent
“You Are What You Measure.”
Conversion expert and author of The Person in Personalization, David Mannheim, will explore how the metrics businesses choose don’t just track performance, they shape behavior and customer experiences.
The challenge is to look beyond easy, short-term metrics like clicks or sales and instead focus on what truly matters: long-term retention, customer value, and authentic relationships.
“Your customer’s goals should be your business goals. If we want to create better experiences and build lasting relationships, we need to shift our focus to more meaningful measures of success.”

“20 years of (in)validation - The evolution of experimentation at Booking.com”
With over a decade in experimentation, Jorden Lentze has seen firsthand how testing can transform decision-making. From safe releases to product validation and innovation, experimentation at Booking.com has become a core driver of growth. Jorden will walk through real examples, practical lessons for teams at any stage, and why storytelling is the most powerful skill for turning data into action.
“Storytelling is absolutely the most valuable skill set for those working in experimentation. It's essential for so many aspects of the job - convincing stakeholders, presenting experiment results in an engaging way, helping internal customers understand data, and creating clear project documentation.”
