Klaviyo, Inc. introduced Composer, an AI‑first agent that can generate, optimize, and recommend complete marketing campaigns and flows from a single prompt. The new tool builds on the company’s existing Customer Agent and other AI models, and is part of a broader wave of more than 75 new features added to the platform in the first quarter.

Composer is a key step toward Klaviyo’s vision of an autonomous B2C CRM, enabling marketers to create full campaigns without manual configuration. By integrating across email, SMS, and other channels, the agent leverages K:AI—the intelligence layer that powers Klaviyo’s AI‑first B2C CRM—to deliver end‑to‑end campaign management.

The launch deepens Klaviyo’s integration with e‑commerce ecosystems. In addition to Shopify, the company expanded its capabilities to WooCommerce, added RCS messaging, Instagram auto‑replies, and other features that position Klaviyo as a central hub for online brands.

Composer builds on the Customer Agent, which now includes new retail skills such as order tracking, returns, subscription editing, and loyalty lookup. These enhancements turn service into a revenue driver and reinforce Klaviyo’s strategy to monetize its customer‑service capabilities.

Klaviyo’s revenue surged 32% over the last twelve months, while its stock has declined 46% in the past six months. Gross profit margin remains strong at 75%, and the company holds more cash than debt. Sixteen analysts have recently raised earnings estimates, reflecting confidence in the company’s AI strategy.

Andrew Bialecki, co‑founder and co‑CEO, said, "The execution layer in software is moving from humans to agents. What matters now is having both the agents that do the work, and the infrastructure that gives them the full picture of the customer." This statement underscores Klaviyo’s focus on agent‑driven automation and the importance of its data platform.
