About Klaviyo
Overview
Klaviyo is an AI-first B2C CRM and marketing platform that unifies customer data, email marketing, SMS, WhatsApp, mobile push, and customer service in a single system. Co-founded in 2012 by Andrew Bialecki and Ed Hallen, it now serves more than 205,000 brands across 100 countries and processes over 2.5 billion events daily.
