157,000+ companies use Klaviyo’s data-driven marketing tools to connect with their customers and grow on their own terms

Our platform unifies all customer data and channels in one place, delivers unprecedented speed and time to value, and is built to be intuitive and easy to use so that every brand—regardless of size and expertise—can connect with their valued customers to grow more profitably and sustainably on their own terms.

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 personalised marketing.

The tech to unite data, analytics, and marketing didn’t exist. So they built it. Today over 151,000+ 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.”

—Andrew Bialecki, Klaviyo co-founder
