Klaviyo Q1 FY26 earnings call KVYO

Klaviyo's strategy centers on leveraging AI agents and infrastructure to help businesses maximize consumer relationships through personalized experiences at scale. The company is closing the 'capability overhang' between its infrastructure and customer utilization, revealing significant demand for intelligence in designing and optimizing consumer experiences. This creates a positive feedback loop where agents use infrastructure, generating data that improves the infrastructure, making agents smarter and more capable, forming an 'autonomous B2C CRM'.

Composer, Klaviyo's next-generation marketing and analytics agent, is in private preview and has shown promising results. It combines subagents for marketing creation (campaigns, automations, content) and analysis (customer behavior, campaign performance). Composer can reason over data, take actions across consumer experiences, and learn from experiments. Early examples include a beauty brand fixing broken automations and identifying new opportunities, an apparel brand seeing a 40%+ increase in top-performing flow revenue, and a personal finance company prioritizing over 1,000 flows in a single session. Composer runs securely within Klaviyo's data perimeter, addressing enterprise data privacy concerns.

The customer agent product has been enhanced with improved LLM intelligence and tool use, allowing businesses to create more tailored agents. Custom skills were launched last week, and it now operates across text, WhatsApp, email, RCS, and web chat, with voice and multilingual support planned. Naked Wardrobe, a digitally native fashion brand, resolved 84% of conversations through customer agent and AI, leading to a 28% increase in average order value. This demonstrates the agent's ability to provide real-time, personalized support and drive sales.

International revenue outside the Americas grew 39% year-over-year in Q1, with EMEA outside the U.K. up 51% for the sixth consecutive quarter. Notable international wins include All Saints (U.K. fashion retailer) and Hobbii (Nordic yarn retailer). Enterprise momentum continued, with new customers in the $50,000+ ARR cohort notably higher than Q1 2025, and the closing of a $6 million+ ARR expansion deal. Examples like Ellis And Olivia, Weber Grills, and Patagonia highlight the trend of consolidating fragmented systems onto Klaviyo's unified platform for improved customer experience and efficiency.

Klaviyo is deepening integrations and expanding partnerships across the AI ecosystem. This includes a deepened integration with Google, launching RCS to all customers and beta access to Google Search and Ads products that connect discovery directly to customer agent experiences. Expanded MCP (Multi-Cloud Platform) connectors with Claude, ChatGPT, and Canva are driving rapid usage, with MCP usage increasing over 10% week-over-week in Q1. Top MCP users show 16% more platform usage, indicating increased data querying and marketing campaign creation.

Amanda Whalen, CFO for nearly four years, announced her decision to step down to spend more time with family before pursuing the next phase of her career. She will remain CFO through August 21, 2026, and in an advisory capacity through November to ensure a smooth transition. A search for her successor has been initiated. Management expressed gratitude for her instrumental role in Klaviyo's IPO and scaling into a global AI-native business.
