“Can a first-party data and marketing automation platform become the dominant customer engagement OS for e-commerce brands globally?”
Founded in 2012, Klaviyo started as an email marketing and automation platform specifically for e-commerce brands, differentiating on first-party data and deep integrations with platforms like Shopify. Over time it expanded from email into SMS marketing and broader customer data platform (CDP) capabilities, becoming a multi-channel marketing OS for direct-to-consumer brands. Its 2022 strategic investment from Shopify cemented its position as the go-to marketing layer for the Shopify ecosystem. In 2023 it went public on the NYSE, underscoring its transition from a startup to a scaled, profitable public SaaS company serving 183,000+ businesses.
