Klaviyo, Inc. reported significant financial growth in its latest 10-K filing for the fiscal year ending December 31, 2025, with total revenue reaching $1.234 billion, a 31.6% increase from $937.5 million in 2024. The company also noted a reduction in net losses, which decreased from $46.1 million in 2024 to $31.8 million in 2025, reflecting a year-over-year improvement of 31.2%. Gross profit for the year was $921.5 million, representing a gross margin of 74.7%, slightly down from 76.4% in the previous year. This decline in gross margin was attributed to increased costs associated with higher usage of text messaging and WhatsApp services, which have higher associated communication costs.
Klaviyo's customer base expanded to over 193,000 by the end of 2025, up from 167,000 in 2024.

The firm has also made strides in international markets, with 39.9% of its revenue derived from customers outside the United States, indicating a successful geographic expansion strategy. The company’s Dollar-Based Net Revenue Retention rate improved to 110% in 2025, up from 108% in 2024, highlighting its ability to grow revenue from existing customers.
Strategically, Klaviyo launched several new products and features in 2025, including the Klaviyo B2C CRM, which integrates marketing, service, and analytics into a single platform tailored for B2C companies. The company also introduced AI-driven capabilities such as Marketing Agent and Customer Agent, which leverage large language models to enhance customer engagement. These developments are part of Klaviyo's broader strategy to position itself as a leader in the B2C CRM space, addressing the unique needs of consumer brands.
Operationally, Klaviyo's workforce grew to 2,368 employees as of December 31, 2025, reflecting its rapid expansion. The company has also invested significantly in research and development, with R&D expenses amounting to $291.2 million, or 23.6% of total revenue. This investment is aimed at enhancing its platform and developing new features, particularly in AI and machine learning, to maintain competitive advantage. Klaviyo's commitment to innovation is evident in its ongoing efforts to integrate AI technology into its offerings, which is expected to drive further growth and operational efficiency.
Looking ahead, Klaviyo anticipates continued revenue growth, although it acknowledges that the pace may decelerate as the business matures.
