About Klaviyo, Inc.

Klaviyo, Inc. (ticker KVYO) is a U.S.-listed technology company traded on the NYSE in the United States (United States). It operates a cloud-based B2C CRM platform designed to help consumer brands and e-commerce businesses centralize customer data, automate marketing workflows, and deliver personalized, real-time customer experiences across channels. The company was founded in 2012 by Andrew Bialecki and Ed Hallen. It began as a customer database business and has evolved into a broader software platform focused on customer activation, segmentation, and omnichannel orchestration. Klaviyo is headquartered in Boston, Massachusetts, placing it within one of the key technology and venture ecosystems in the U.S. Klaviyo’s business model is primarily subscription-based, with revenue driven by the adoption of its software platform by digital merchants and consumer brands. Its core product suite includes email marketing, SMS marketing, automation flows, customer segmentation, analytics, and increasingly AI-enabled tools intended to speed up campaign creation and improve the use of customer data. The company also emphasizes its Klaviyo Data Platform, which unifies profiles and event-level consumer data so marketers can build more precise and scalable engagement strategies. From a competitive standpoint, Klaviyo operates in a crowded marketing software market, but it has carved out a differentiated position through its B2C specialization, strong product depth for commerce-centric use cases, and close integration with major commerce ecosystems such as Shopify. That positioning is particularly relevant for brands seeking stronger retention, higher marketing efficiency, and more automation. The company serves an international customer base and has expanded beyond the Americas, with growing activity in Europe and Asia-Pacific supported by regional hubs in Dublin and Singapore. Recent developments have been notable. In February 2026, Klaviyo reported full-year 2025 results showing 32% revenue growth and improved profitability, and it raised its fiscal 2026 outlook. In March 2026, the company announced a share repurchase authorization of up to $500 million, including a planned $100 million accelerated share repurchase, underscoring management confidence in cash generation and the durability of the business model. Klaviyo also highlighted new AI integrations and strategic partnerships with Google and Shopify, reinforcing its push toward more autonomous customer experiences and deeper commerce connectivity.
