Klaviyo fuels growth.

Who we are

We’re a team of people who are crazy motivated by growth. It’s what we help our customers do: grow their businesses faster. It’s how we behave as individuals: we’re all deeply passionate about stretching, learning, and pushing boundaries. It’s how we manage our business: we have thousands of paying customers, we’re profitable, and we’re growing insanely fast. And it’s what our culture is all about.

Becoming a Klaviyo means you’ll tackle projects you never imagined you would. You’ll solve problems others consider unsolvable. You’ll grow in ways you didn’t consider possible. And you’ll do the best work of your career with people who are just as smart, collaborative, committed, and talented as you are.

We do things a little differently

Klaviyo enables modern communication between companies and consumers. We’re committed to pushing the boundaries of what’s technically possible and making it truly accessible to any online business, from entrepreneurs to leading enterprise brands. Our platform processes billions of consumer activities, or data events, every month — and then makes them available in real-time to fuel better targeting, deeper analysis, and more effective marketing. That means our customers can create incredibly personal email and advertising experiences without wasting their time or money. And it works: we’re proud that our customers grow 29% faster on average after making the switch to Klaviyo. That’s why over 10,000 of the most innovative brands like Brooklinen, Bonobos, Untuckit, and Taylor Stitch power their marketing through Klaviyo.
