About

Leading e-commerce-native marketing automation and CDP platform, dominant among Shopify merchants and DTC brands

Klaviyo is a Boston-based marketing automation and customer data platform (CDP) founded in 2012, purpose-built for e-commerce and direct-to-consumer brands. The platform enables businesses to collect, unify, and activate customer data to deliver personalized communications across email, SMS, push notifications, and more. Klaviyo's deep integrations with e-commerce platforms like Shopify, WooCommerce, and Magento allow brands to leverage real-time behavioral data, purchase history, and predictive analytics to drive highly targeted campaigns that generate measurable revenue. Klaviyo occupies a strong position in the marketing automation space by differentiating itself from legacy email service providers through its robust CDP capabilities, ease of use, and e-commerce-native data model. Unlike general-purpose marketing clouds, Klaviyo is designed from the ground up for online retailers and DTC brands, making it a preferred choice for businesses ranging from small Shopify stores to large enterprise e-commerce operations. The platform's ability to tie marketing activity directly to revenue has made it a staple in the modern e-commerce tech stack. Klaviyo went public on the New York Stock Exchange in September 2023 under the ticker 'KVYO,' raising approximately $576 million in its IPO and achieving a valuation of around $9 billion at listing. The company has grown rapidly, serving over 130,000 paying customers globally and reporting annual recurring revenue exceeding $700 million as of 2023. Klaviyo's strategic partnership with Shopify, which holds an equity stake in the company, further cements its dominance in the e-commerce marketing automation segment.
