Klaviyo is an intelligent marketing automation platform designed primarily for e-commerce businesses, enabling them to acquire, retain, and grow their customer base. It centralizes customer data from various sources (like e-commerce platforms, POS systems, and websites) into a unified profile. Klaviyo uses this data to facilitate personalized and targeted communication across multiple channels, including email, SMS, mobile push notifications, and in-app messages. The platform leverages data science to help businesses understand customer behavior, segment audiences effectively, automate marketing workflows, and ultimately drive revenue growth through more relevant customer experiences.
Serves as the global operational hub, housing key functions like executive leadership, product development, engineering, core marketing, sales strategy, and administration.
Located in a prominent high-rise building in Boston's Financial District, the office features modern, open-plan workspaces, collaborative zones, employee amenities, and advanced technology infrastructure.
The HQ fosters a fast-paced, innovative, and collaborative environment. Emphasis is placed on customer-centricity, data-driven decision-making, ownership, and transparency. Frequent cross-functional team interactions are common.
Boston's status as a major technology and innovation hub provides access to top talent (especially from nearby universities like MIT and Harvard), venture capital, and a thriving ecosystem of partners and potential customers. It anchors Klaviyo's significant presence in North America.
Beyond its headquarters in Boston and major hubs in London and Sydney, Klaviyo maintains a global presence supporting customers worldwide. Key functions distributed internationally include regional sales teams, customer success managers providing 'follow-the-sun' support, localized marketing efforts, and partnership management. While core engineering is concentrated, Klaviyo may leverage remote talent globally to support its platform and operations across different time zones and markets.
