Company Overview

Our Story:

Before starting Klaviyo in 2012, we spent time at Google, Performable (acquired by HubSpot) and Applied Predictive Technologies (acquired by Mastercard) using data and technology to help marketers get smarter at many of the world’s largest companies.

Over the last four years, Klaviyo has grown from two people to a team of over 50 people in downtown Boston. From fast growing ecommerce stores to some of the world’s largest companies, we work with thousands of companies around the globe to send tens of millions of emails every day.

Bootstrapped and profitable from the start, in 2015, we partnered with Accomplice to allow us to go faster.

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.
