Experimentation island (#Ei2026)

Ei2025 is over, but planning is well under way for 2026! We’re bringing the brightest minds in optimization back together for an exclusive event. It’s one of the very few non-vendor optimization conferences in the US, and this one is truly special.

#Ei2026 is where optimizers share and learn how to improve results.

Here’s why:

All-inclusive Experience: Your ticket covers your hotel, meals (including two 3-course dinners!), and activities—making it easy to focus on learning and networking.
Diverse Content: The conference is packed with 1/3 single-track keynotes from leading experts, 1/3 unconference-style breakout sessions (giving you a chance to join the conversation or become the speaker), and 1/3 quality networking events—all designed to foster connections and inspiration.
Community Driven: #Ei2026 is organized by the Test & Learn Community (TLC) nonprofit. It is hosted & founded by Ton Wesseling, founder of the Optimizers Community, and is open to everyone interested in experimentation, no matter your industry or company size.
Fun & Engaging Atmosphere: Beyond the learning, we’ve got parties and social events planned each night—because innovation thrives when we mix work and play.

So whether you're looking to connect with peers, share ideas, or soak up fresh perspectives on experimentation, #Ei2026 is the place to be.

Space is limited, so I encourage you to secure your spot as soon as possible. You can find more details about our speakers from 2025 and register for our reminders below.

We offer three types of sponsorships at Ei2025: Event Partnerships, Community Partnerships, and Media Partnerships. Event Partners are vendors who will host breakout sessions, have a booth, and run team games. Community Partners are agencies or consultancies that help promote the event to their networks and can purchase discounted bundled tickets for clients. Media Partners are community members who want to help promote the event in exchange for a free ticket for their community. Reach out to Kelly to learn more.
Ei2025 will took place on beautiful St. Simons Island, GA, at Sea Palms. We had exclusive use of the hotel for the conference. Your ticket included your stay, meals, and all activities—it’s all-inclusive! We’ll let you know ASAP about Ei2026!
If you’re flying in, we recommend Jacksonville, FL (about 70 miles south) as the nearest major airport. During registration, you’ll have the option to sign up for our airport shuttle. If you’re using the shuttle, aim for flights that arrive by 11:00 AM, as the shuttle departs Jacksonville at 11:30 AM. Savannah, GA, is another option, about 85 miles north, though fewer flights are available. (You will need to arrange alternative transportation to Sea Palms from Savannah).

We’re curating a special event for everyone - including you. That means making sure we have the right mix of attendees to foster great conversations and learning opportunities. We limit registration to no more than three people per brand, ensure a balance between client-side, agency, and vendor attendees, and aim to include voices from across product, UX, marketing, data, and, of course, experimentation. The goal is to create an environment where learning extends beyond the sessions and continues over dinner and downtime.
You’re in good company—Ei2025 was brand new, so most folks will be new.
Our event app (which will go live before the event) will help you connect with others beforehand. Plus, our crew and Event/Community Partners will be there to guide you, introduce you to other attendees, and help you feel right at home.
