Klaviyo is an American technology company specializing in marketing automation platforms, primarily focused on email and SMS marketing for e-commerce businesses. Founded in 2013 by Andrew Bialecki and Ed Hallen, both formerly of Applied Predictive Technologies, Klaviyo has grown into a leading customer relationship management (CRM) platform designed for business-to-consumer (B2C) engagement and automation. The company supports approximately 143,000 merchants, most of whom leverage the platform in conjunction with Shopify to optimize their sales and customer communication strategies.

Headquartered in Boston, Massachusetts, Klaviyo maintains multiple offices worldwide including locations in Denver, San Francisco, London, Dublin, and Sydney, reinforcing its global presence. The company’s name, Klaviyo, is derived from the Spanish word “clavija,” meaning mountaineering pins or pitons, symbolizing the company’s mission to act as a reliable support for its customers as they grow.

Klaviyo has attracted significant attention and investment within the tech and e-commerce space, notably receiving a $100 million strategic investment from Shopify in 2022 when it was designated as the recommended email solution partner for Shopify Plus merchants. Later that year, Klaviyo made its first acquisition, Napkin.io, to expand its capabilities in code development.

In 2023, Klaviyo went public with an initial public offering (IPO) on the New York Stock Exchange, raising $576 million and achieving a valuation of $9.2 billion at the time. The company continues to innovate its marketing platform, including localizing its software into six additional languages by 2024 to better serve a diverse global customer base. Klaviyo’s platform features tools such as predictive analytics, customer data integration, and automated marketing workflows, enabling merchants to create personalized and effective marketing campaigns.

Overall, Klaviyo stands as a prominent player in the marketing automation and e-commerce software industry, empowering businesses to build stronger relationships with their customers through data-driven communication and automation.
