How it started

In 2012, Klaviyo co-founders Andrew Bialecki and Ed Hallen saw a pattern. Companies had loads of data but couldn’t answer basic questions about their customers, let alone use that data to drive revenue through personalized marketing.

The tech to unite data, analytics, and marketing didn’t exist. So they built it. Today over 146,000 of the world’s most notable brands use Klaviyo’s email and SMS marketing platform.

“Klaviyo provides the tools and playbooks for any creator to have more control, more ownership. It doesn’t matter if you create products, services, or content—or some of each. We believe the best products and creations can and should win.”

What’s with the name?

Klaviyo (clay-vee-oh) is inspired by “clavija”, a Spanish word for mountaineering pins—also called pitons. These pitons support climbers as they ascend, and catch them if they fall.

We liken our customers to mountaineers. Our goal is to support and accelerate their climb to the summit.
