Tammy Everts

Chief Experience Officer at SpeedCurve

Tammy has spent the past two decades studying how people use the web. Since 2009, she’s focused on the intersection between web performance, user experience, and business metrics. Her book Time Is Money: The Business Value of Web Performance (O’Reilly, 2016) is a distillation of much of this research (but there’s always more to be learned).

Tammy is a frequent speaker at events like Shop.org, IRCE, and Smashing Conference. She also co-curates WPOstats.com, an ongoing collection of performance case studies.
