About Us
Klaviyo is building the future of how e-commerce businesses grow and talk to their customers, powered by data science.
Over the last 3 years, Klaviyo has grown from 2 people to a team of over 130 people in downtown Boston. From fast-growing ecommerce stores to some of the world’s largest companies, thousands of companies around the globe send tens of millions of emails every day with Klaviyo.
Our approach
Klaviyo has built database technology to make 1:1 personalized email easy. For too long companies were stuck blasting everyone with the same email. Not because they think that’s what their customers want, but because they don’t have a choice.
Klaviyo fundamentally changes the game. Our software aggregates everything a business knows about their customers into individual profiles in our customer analytics database. We’ve paired that with an email platform that makes designing beautiful emails easy. Those pieces together, Klaviyo is one unified platform for personalized, 1:1 email that drives results.
