Klaviyo is the AI-first B2C CRM platform built for direct-to-consumer and retail brands. It unites marketing automation, analytics, and customer service around a single data layer, enabling businesses to act on customer behavior in real time instead of stitching together separate tools.

The platform was founded in 2012 to solve a fundamental problem: consumer brands had access to vast amounts of customer data but lacked the technology to use it for personalization and revenue growth. Klaviyo's data-first approach has evolved from a customer database into a unified CRM that combines data management, marketing, service, and analytics into one solution, allowing brands to build lifelong customer relationships at scale.
