Built to solve the customer data problem

In 2012, Klaviyo co-founders Andrew Bialecki and Ed Hallen saw a frustrating pattern: consumer brands were sitting on mountains of data but couldn’t use it to personalize experiences or drive revenue.

The tech to unite data, analytics, and marketing didn’t exist. So they built it.

Today, 183,000+ brands worldwide use Klaviyo not just to sell but to create lifelong customer relationships.

“At Klaviyo, we’ve always believed that building customer relationships starts with your data—and it shouldn’t be complicated. We help businesses of all sizes unlock the full potential of their data to build lifelong relationships and grow smarter, faster, and without compromise. That’s the power of customer-first data.”
