Experiment Effectively
August 26, 2025

Leemay Nassery's notable track record includes, among other things, evolving Spotify’s A/B testing strategy for their homepage, launching Comcast’s "For You" page, and establishing data warehousing teams at Etsy. So when we say she knows much more than a thing or two about experimentation and personalization, we aren't kidding.

We recently sat down with Leemay to discuss A/B testing, platform capacity, product organization culture, identifying and adding value to your code base, adapting to future changes, and much more. Along the way we explored what it means to be truly curious, and we discussed how to develop the courage to act boldly on the results of your experiments.

Check out the full interview at https://forum.devtalk.com/t/spotlight-leemay-nassery-author-ama-and-interview/210093, and be sure to drop a question into the AMA thread. Every discussion participant has a chance at winning a free ebook copy of either Practical A/B Testing or Next-Level A/B Testing.
