Bio
Shortbio
Karlijn Löwik is CEO & Co-founder of RUMvision, on a mission to make web performance a business priority for every eCommerce company. Based in Groningen (NL), she’s an international web performance speaker, RUM-advocate, and champion for women in tech, like the Lady Magento iniative. She serves as co-chair for the RUM W3C Group and as a board member of Mage-OS NL. She coined the term Sitespeed User Experience (SUX) – because let’s face it, good SUX sells! 😉
Longer bio for solo talks
You might know Karlijn Löwik for one of these two things: terrible puns about SUX (Sitespeed User Experience) or her memes that make learning about Core Web Vitals actually fun. As CEO & Co-founder of RUMvision, a real user monitoring company, she works to make web performance accessible to everyone.
Based in Groningen with her 4-year-old, Karlijn's talk titles are hard to forget - think "SUX on the Beach" for summer conferences and "SUX and the City" in New York. She serves as co-chair for the RUM W3C Group and board member of Mage-OS NL, building communities that care about performance and beyond.
Her work takes her around the world as an international speaker, and she's gotten good at turning business trips into family adventures. When not creating memes or working, Karlijn loves to dance, cook, make cocktails (with rum, obviously), and advocate for women in tech.
Karlijn's mission is simple: help everyone understand why site speed matters, preferably while laughing. Because good SUX really does sell.

As CEO & Co-founder of RUMvision, a real user monitoring company, she works to make web performance accessible to everyone. The fact that she co-founded the company with her web performance specialist husband Erwin Hofman just makes their story even better.

She speaks at events solo or sometimes with Erwin (they haven't managed to kill each other on stage yet).
