It reported $1.23 billion in fiscal 2025 revenue and has no parent organization.
Klaviyo launched in Boston in 2012 with a data first insight. Founders Andrew Bialecki and Ed Hallen, previously at Applied Predictive Technologies, believed consumer brands already had the customer data they needed but no software to use it. They built a customer database before building any messaging on top.
For its first years the company grew slowly and mostly bootstrapped, unusual discipline for a SaaS startup of its era. The breakthrough came from the Shopify ecosystem. As direct to consumer brands proliferated through the mid 2010s, Klaviyo's deep Shopify integration made it the default email platform for that generation of merchants.
Revenue compounded at high double digit rates through the late 2010s. A $320 million raise in 2021 valued the company above $9 billion, and the September 2023 IPO was one of the first major tech listings after a long market drought, priced at $30 per share.
The brand has since repositioned from email tool to B2C CRM. The 2025 additions of reviews, service features, and AI pushed the platform beyond messaging, while international expansion through Dublin and Singapore hubs and a push into mid-market and enterprise accounts broadened the customer base.
