Klaviyo

Builds marketing software for consumer brands

Overview

Klaviyo builds customer relationship software for consumer brands, combining marketing, customer service, analytics, and a customer data platform in one system. Its platform draws on shoppers' purchases, browsing, and message activity to create customer profiles that brands use to personalize communications. Businesses use these profiles to automate email, text, WhatsApp, and mobile push campaigns, while AI agents create marketing work and answer customer questions. Klaviyo earns subscription fees based on active customer profiles, message volumes, and service activity, rather than charging for each employee who uses the software. Founded in 2012, the company is headquartered in Boston, Massachusetts.

Klaviyo Q3 revenue climbs 25% as AI agents and enterprise adoption expand.

Klaviyo Q3 revenue climbs 25% as AI agents and enterprise adoption expand. Published on: Nov 5, 2026 Klaviyo reported third-quarter 2026 revenue of $387.2 million, up 25% year over year, as the marketing technology company expanded its AI agent capabilities and increased adoption among larger customers. The results, for the quarter ended September 30, show the company continuing to position its platform as an autonomous business-to-consumer (B2C) CRM, combining customer data, marketing decisioning, and AI-powered tools for marketing and customer service. Its latest product developments include an upgraded Composer experience, Klaviyo Headless, and embedded integrations for Shopify and Wix. Klaviyo's latest results point to two connected priorities: expanding its enterprise customer base and making AI agents a more central part of its customer relationship management platform. While revenue growth remained strong, the company's product announcements suggest it is also preparing for a shift toward AI systems that can access customer data and execute tasks across marketing workflows. The company generated $387.2 million in Q3 revenue, representing 25% year-over-year growth. Gross profit was $287.4 million, with a GAAP gross margin of 74%. Non-GAAP operating income reached $56.9 million, equivalent to a 15% operating margin. Klaviyo reported a GAAP operating loss of $4.5 million. Cash from operating activities was $52.7 million, while free cash flow was $24.8 million and adjusted free cash flow was $40.1 million. AI agents become a bigger part of Klaviyo's CRM strategy. Klaviyo's product strategy increasingly centers on connecting customer data with AI-driven decision-making. CEO Andrew Bialecki described the company's customer data foundation as an advantage as AI agents take on more marketing and customer service work. The company released a new version of Composer, which it describes as more autonomous and proactive, with connectors, skills, and artifacts. The announcement signals a move toward agents that can work with connected systems and use business context to support more complex tasks, rather than functioning only as isolated content-generation tools. Klaviyo also announced Klaviyo Headless, which allows customers to access Klaviyo data from external AI systems, including Claude and ChatGPT. This is strategically relevant as businesses explore ways to connect customer information and marketing workflows to AI assistants beyond a single software interface. The company also launched embedded applications, including Klaviyo in Shopify and Klaviyo in Wix. These integrations bring Klaviyo and Composer capabilities directly into merchant workflows, reducing the need to switch between separate platforms. Enterprise customer growth outpaces overall expansion. Klaviyo reported more than 211,000 customers as of September 30, 2026. Its larger customer segments grew faster than the overall business. The company had 4,725 customers generating more than $50,000 in annual recurring revenue (ARR), up 33% year over year. The number generating more than $250,000 in ARR increased 49% to 390, while customers generating more than $500,000 in ARR rose 57% to 105. These figures suggest that existing customers are expanding their platform usage and that Klaviyo is making progress in larger accounts. The company also reported that 22% of ARR came from customers using three or more products, indicating growing adoption across its platform portfolio. Net revenue retention (NRR) was 108%, reflecting expansion, cross-selling, and retention among existing customers. Revenue outside the Americas grew 32% year over year, pointing to continued international expansion. Klaviyo identified new customer wins and expansions involving Frasers Group, Malbon Golf, and Voluspa, although it did not disclose individual contract values. Full-Year guidance and share repurchase. For the fourth quarter, Klaviyo expects revenue between $421 million and $425 million, representing approximately 21% year-over-year growth. Its full-year 2026 revenue guidance stands at $1.537 billion to $1.541 billion, with expected growth of approximately 25%. The company forecasts full-year non-GAAP operating income of $233 million to $236 million. These are non-GAAP measures and should be considered separately from its reported GAAP operating results. Klaviyo also authorized a new $300 million share repurchase program after completing its previous $500 million authorization in October. The company said its cash generation allows it to balance investment in product development with capital returns to shareholders. The results place Klaviyo at the intersection of marketing automation, customer data infrastructure, and enterprise AI. Its ability to turn agent capabilities into sustained customer adoption and measurable marketing outcomes will be an important factor in its next stage of growth. Market landscape. The marketing technology market is moving toward platforms that combine customer data, campaign execution, personalization, and AI-driven decision-making. As generative AI and autonomous agents become more capable, access to reliable customer context is emerging as a competitive factor. Klaviyo's strategy reflects this convergence. Its CRM platform connects customer profiles and engagement data with marketing and customer service workflows, while Composer and Headless extend how users and external AI systems can interact with that infrastructure. The move also places greater emphasis on interoperability. Integrations with Shopify and Wix address merchants working within commerce platforms, while access through Claude and ChatGPT points toward a broader ecosystem in which AI assistants may become another interface for enterprise applications. Competition will increasingly depend not only on AI features, but also on data quality, integration depth, governance, workflow reliability, and the ability to demonstrate commercial returns. Strategic outlook. Klaviyo's Q3 performance demonstrates continued revenue growth and expansion among larger customers. Its next challenge is converting AI product development into deeper platform adoption and measurable customer outcomes. Three areas will be important: * Agent adoption: Whether Composer can move beyond assisting individual tasks to reliably coordinate more complex marketing and service workflows. * Open AI connectivity: Whether Klaviyo Headless encourages meaningful usage through external AI systems while maintaining appropriate data access and controls. * Enterprise expansion: Whether larger customer cohorts continue growing and adopting multiple products, supporting retention and recurring revenue. The company's 108% NRR indicates expansion within its existing customer base, but it also means sustained growth will depend on winning new customers and increasing the value generated from current accounts. Its reported financial performance provides a strong foundation, while the commercial impact of its newer agent capabilities remains to be demonstrated over time. Top insights. * Klaviyo generated $387.2 million in Q3 2026 revenue, up 25% year over year, with a 74% GAAP gross margin. * Composer's latest release adds connectors, skills, and artifacts as Klaviyo expands its autonomous AI capabilities. * Klaviyo Headless opens access to platform data from external AI systems, including Claude and ChatGPT. * Customers generating more than $250,000 in ARR increased 49% year over year, reaching 390. * Net revenue retention reached 108%, while 22% of ARR came from customers using at least three products.

Loop uses AI to transform retail returns experience.

Loop uses AI to transform retail returns experience. Samir Kamnani, Senior International Programme Manager at Loop, specializes in helping retailers leverage technology to enhance the returns and post-purchase experience. With a background in product marketing and computer information systems from Chapman University, Kamnani has transitioned from Spireon to ecommerce and retail technology, focusing on balancing customer experience with profitability at Loop. Loop's ai-driven approach to returns management. Loop operates as an operations platform centered on retention, enabling brands to build customer confidence throughout the shopping journey. The company emphasizes simplifying the post-purchase experience, including tracking, returns, exchanges, protection, and customer support, transforming these touchpoints into opportunities for engagement. Trusted by over 5,000 brands, Loop has processed more than 100 million returns and offers tools like Workflows, Instant Exchanges, Shop Now, Checkout+, and Bonus Credit to reduce costs and increase customer lifetime value. Loop's competitive edge lies in its proprietary AI engine, trained on data from over 200 million shoppers, 100 million returns, and 1.4 billion shipments. This enables retailers to predict consumer behavior, encourage exchanges, and identify fraudulent activities. A recent report, The Returns Revenue Gap, revealed that 55% of British shoppers have abandoned purchases or stopped shopping with retailers due to returns policies, highlighting the direct impact on revenue and loyalty. Implementation focuses on seamless integration with existing ecommerce infrastructure, with success measured through metrics like exchange adoption, retained revenue, and refund rates. Best practices involve using data to understand return reasons and guide next steps. Challenges and opportunities in UK retail for 2027. UK retailers face pressure to protect margins while meeting consumer expectations for convenience. Fraud is another growing issue, as 31% of UK consumers admit to providing inaccurate return reasons, while 56% of retailers still rely on manual reviews to detect fraud. According to Kamnani, the opportunity lies in using data to manage returns intelligently - encouraging exchanges, reducing friction, and identifying risks. Loop aims to shift retailers from reactive to proactive strategies by leveraging AI to predict behavior, personalize experiences, and protect revenue. With 56% of retailers still using manual reviews for fraud detection, there is significant potential for technology adoption to streamline processes and enhance retention. Strategic partnerships powering Loop's ecosystem. Loop's effectiveness stems from its extensive network of over 6,000 partners across the ecommerce ecosystem. These collaborations include marketing and development agencies, logistics providers, and technology platforms that brands depend on for seamless operations. Key partners in the UK, such as Vervaunt, Domaine, and VisualSoft, specialize in enhancing the pre-and post-purchase experience through strategic expertise. Technology integrations with Shopify, Klaviyo, and Gorgias enable Loop to embed its AI-driven tools directly into retailers' existing systems. Shipping and fulfillment partnerships with OpenBorder, Sendcloud, and Global-e further streamline cross-border returns and reverse logistics, reducing friction for international shoppers. The company's 120 technology integrations showcase its commitment to interoperability. These partnerships allow brands to combine Loop's retention-focused platform with tools that optimize marketing, inventory management, and customer support. By aligning with industry leaders, Loop empowers retailers to create cohesive customer journeys while maintaining operational efficiency. The collaborative approach ensures that brands can scale globally without overhauling their core infrastructure, a critical factor for retailers managing complex, multi-channel operations. AI expansion and proactive returns strategies. Loop is advancing its AI capabilities beyond product recommendations and fraud detection to forecast returns and personalize the customer journey. By analyzing data from every interaction, it aims to shift retailers from reactive processing to proactive engagement. Kamnani emphasizes that each return generates actionable insights, enabling brands to refine products, optimize inventory, and anticipate customer needs. This transformation positions returns as a strategic lever for retention rather than a cost center. The company's vision includes embedding AI more deeply into pre-purchase stages, using predictive analytics to identify high-risk returns before they occur. Early indicators from Loop's platform suggest that integrating AI into returns workflows can reduce manual reviews by automating decision-making for low-risk cases. With only 16% of retailers currently using AI for fraud detection, the potential for scalable, intelligent systems remains significant. Loop's goal is to turn every return into a data point that strengthens customer relationships and operational resilience. Research indicates that 76% of retailers acknowledge the returns experience's impact on loyalty, yet only 6% prioritize customer churn as a post-purchase challenge. Closing this gap requires retailers to adopt data-driven approaches that align customer satisfaction with business outcomes. Loop's tools, such as Workflows and Instant Exchanges, automate these strategies, ensuring that returns become a seamless extension of the shopping journey rather than an endpoint.

Singapore leads Asia in AI-powered holiday shopping.

Singapore leads Asia in AI-powered holiday shopping. Singapore shoppers are leaning on artificial intelligence to plan this year's festive gift-buying more than any other market surveyed, according to new research from Klaviyo, released at the marketing platform's inaugural K:SGP event in the city on Tuesday. The event marked the first regional edition of Klaviyo's global K:SGP series, coming two months after the autonomous B2C customer relationship management (CRM) platform opened its Asia headquarters in Singapore in August. Singapore shoppers lead the region on AI-assisted shopping. Klaviyo's State of the Holiday Buyer Report 2026, which surveyed 500 consumers in Singapore as part of an eight-market study, found that 81 per cent of local shoppers plan to use AI to search for holiday gifts this year, the highest adoption rate of any market surveyed. Shoppers who use AI assistants are also likely to spend more. The report found that 31 per cent of AI-assisted shoppers plan to spend more than they did last year, compared with 10 per cent of shoppers who do not use AI, a three-fold difference. Close to one in five Singapore shoppers now list AI assistants as a top source for gift ideas, ahead of brand emails. Relevance appears to matter more to shoppers than who, or what, writes a message: 60 per cent of respondents assume brand communications are already AI-generated, and 55 per cent said they do not mind whether content is written by AI or a person, as long as it is relevant. Email remains the most preferred channel at 52 per cent, though nearly half of consumers said they prefer SMS, WhatsApp or mobile app notifications. "AI is changing how people discover and spend, and nowhere is that clearer than in Singapore," said Ed Hallen, co-founder and chief strategy officer at Klaviyo. "This holiday season, more shoppers will start with an AI assistant to find the right gift and will spend more. That's a big opportunity for businesses who are ready to meet them." New tools let marketers keep control of AI personalisation. Alongside the research, Klaviyo detailed updates to two AI tools built for brands on its platform. Composer, its marketing agent, can now flag issues such as an underperforming campaign on its own, rather than waiting for a prompt. Customer Agent, its AI support tool, answers shopper questions in more than 100 languages and displays local currency to simplify cross-border sales. Both tools draw on a brand's own customer data to decide who to contact and when, while marketers set the goals and limits those systems work within. "Consumers aren't asking whether a brand used AI to create something. They're asking whether it's relevant to them," said Jamie Domenici, chief marketing officer at Klaviyo. "AI should be doing the heavy lifting, not replacing the marketer." Singapore-founded Castlery among early adopters. Singapore-founded furniture retailer Castlery is among the brands using Klaviyo's tools across email, SMS and WhatsApp. The company said automated flows built on the platform now drive 74 per cent of its Klaviyo-attributed revenue in the first half of 2026, as it shifts focus from acquiring new customers to retaining existing ones. "Our focus now is on building relationships that last, which means understanding how customers want to furnish their homes and building flows that anticipate what they need next," said Leah Howatson, general manager, international markets at Castlery. Klaviyo counts more than 205,000 paying customers globally, including Mattel, TaylorMade, Glossier and Liquid Death. Share with your friends: Discover more from techcoffeehouse.com. Published by
