My first year at Conversion Hotel. The speakers, vendors and organisation were all brilliant, but the best part was connecting with so many wonderful people from across the experimentation space.

Iqbal
Experimentation Coach & Consultant
I’d heard a lot of positive buzz about Conversion Hotel, having now attended, I can see why. Being in a hotel with likeminded people allowed me to learn so much and make so many great friends. It really did feel like one big family. Amazing.

As a first time attendee, I came with no expectations but left inspired and with answers to so many of my questions.

Best place for experimenters to learn, connect and make friends for live.

I had heard from so many people how great this conference is, so I went in with very high expectations. Those expectations weren’t met; they were exceeded!

People who explore, learn, share, and connect
I’m still glowing from this year’s edition of The Conference known as Conversion Hotel The quality was outstanding! The attendees, the speakers, the hotel staff, the AV team, the theme design… and of course, the incredible #CH2025 crew.
It’s so delightful to host this event. Once again, it felt like one big family, a family with a growth mindset. People who explore, learn, share, and connect. People who are not afraid to try, fail, reflect, and openly exchange experiences. That’s what makes this event so special.
🌼 We will donate a 100 square meters Flower Field to our event island Texel, on behalf of the winning team of the attendee games: Bonzai Panthers!
🌳 To compensate the CO2 footprint of our event (and the attendees’ travel), and with some extra donations from our attendees, we will donate €4560 to our Conversion Hotel tree fund (which is supporting tree planting in the Netherlands).
Save the dates for next year 📅 November 20/21/22, 2026 Same island. Same energy. Updated learnings.
But first, I’m crossing the ocean. On February 24/25/26, 2026 I’ll bring this experience to the US again with the second eddition of The Conference known as Experimentation island on St. Simons Island, Georgia!
See you there, or next year at #CH2026!
