1 How we created this list

A/B testing is an exciting and rapidly developing field, and testing professionals everywhere are looking for thought leadership that can help them raise the bar on their experimentation programs. To that end, we’ve prepared this list of 82 influencers in A/B testing in 2021.

We selected the experts on this list based on their overall profile in the industry, recent publications, conference speaking engagements in 2020 (including online), and social media presence. We've listed them alphabetically and refrained from including anyone that works for Kameleoon itself!

To give you a sense of the expertise these influencers bring to A/B testing, we’ve included a Noteworthy Content section for each, featuring relevant articles, interviews, podcast appearances, and conference presentations. You can also connect with these thought leaders via the links to their social media profiles and websites.

This list includes many of the top experts on A/B testing today, but we know it’s not definitive. Know of someone who you think should be included here? Drop us a line to hello@kameleoon.com
