If you've ever wondered who's behind the technical side of RUMvision, it's Erwin. CTO, co-founder, Google Developer Expert, and international speaker. He built version 1.0 during his paternity leave, in the hours when his daughter Hannah was asleep. Four years later, with 2.0 now live, his role is changing. And that's precisely what he wanted.

Super proud moment, RUMvision 2.0 is LIVE 🎉 It has taken a lot of hard work, a lot of talking, and - most importantly - a lot of listening to our clients. But this new version truly puts the "vision" into RUM. Let us tell you what we've build and how it can help your business.

Karlijn is the person who translates web performance into something everyone can understand. She's CEO and co-founder of RUMvision, co-chair of the W3C RUM Community Group, board member of Mage-OS NL, and the one who coined SUX (Sitespeed User Experience). Because good SUX sells.She speaks at conferences across the world, sits at the table with Google and other browser vendors, and runs a company with her husband. She also spent this morning vacuuming the office before this interview.

Roderik is the one thinking three steps ahead, turning technical possibilities into business models. He’s our co-founder and oversees business development, business administration, partnerships, and marketing strategy, but you probably won’t see him on stage or in your inbox. Next to RUMvision, he’s been running his own marketing company since 2009.

I’m the co-owner, manage customer success, and the person you’ll probably talk to first when you start using RUMvision. But did you know: four years ago, I was selling organic tea from home?
