Attentive promotes Eric Miao to Chief Executive Officer.

Attentive promotes Eric Miao to Chief Executive Officer. Attentive has promoted co-founder Eric Miao to Chief Executive Officer, placing a founding team member at the helm as the marketing technology company continues to expand its focus on AI-powered customer engagement. Miao has been with Attentive since its early stages and has held several leadership roles across the company. Before taking the CEO position, he served as Chief Strategy Officer and Chief Product Officer, where he was involved in the company's product and AI strategy. His earlier work included creating and leading Attentive's customer success organization. The leadership transition comes as Attentive moves beyond its origins in SMS marketing toward a broader omnichannel marketing platform spanning SMS, email, RCS, push notifications, and AI-based capabilities. The company has been increasing its investment in AI systems designed to help marketers use customer signals for audience segmentation, campaign planning, reporting, and personalization. Miao's appointment also comes after a period of significant product development around agentic AI. In May, Attentive outlined a roadmap that included AI Campaigns, Predictive Analytics, Reporting Agent, and expanded Brand Voice capabilities. More recently, the company introduced additional AI functionality focused on customer lifecycle intelligence, including product affinity, RFM analysis, and customer lifetime value. As CEO, Miao is expected to guide the company's next phase around AI and personalized marketing. His background across product, customer success, strategy, and AI places the leadership transition closely alongside Attentive's shift toward technology that can interpret customer data and support more automated marketing decisions. The change also marks a leadership transition from Amit Jhawar, who had been serving as Attentive's CEO. Earlier in 2026, Jhawar was the company's CEO while Miao served as Chief Strategy Officer and Chief Product Officer. For the broader MarTech industry, the move reflects how AI is increasingly influencing the leadership and product strategies of customer engagement platforms, particularly as marketers look for ways to combine first-party data, personalization, automation, and human oversight.

Catalyst Brands moves off legacy martech stack to power 1:1 personalization across its portfolio.

Catalyst Brands moves off legacy martech stack to power 1:1 personalization across its portfolio. Attentive(R), the omnichannel marketing platform for retailers, apparel brands, and e-commerce companies redefining how brands and people connect through relevant personalized experiences, announced that Catalyst Brands, the recently formed parent company of JCPenney, Aeropostale, Brooks Brothers, and other leading retailers, has transitioned to Attentive's omnichannel platform for SMS, email, push, and AI-powered decisioning. This migration reflects a broader transformation within the retail industry, as the traditional martech model, characterized by fragmentation, high costs, and a lack of purpose-built AI, becomes obsolete. Nearly half (47%) of marketing leaders cite their current stack as a barrier to value, according to McKinsey. Attentive delivers a leaner, consolidated approach that prioritizes data clarity, revenue and connection, making it possible for marketers to drive real-time personalized experiences at scale. Catalyst Brands' predecessor organization began working with Attentive in 2020 and expanded the relationship in March 2025 to include the entire Catalyst Brands portfolio on Attentive's omnichannel platform. The migration to Attentive consolidated billions of customer interactions across all Catalyst brands into a single platform, removing the need for multiple point solutions and CDP dependencies, and delivering efficiencies that resulted in annual cost savings. From fragmentation to consolidation. "When bringing together five distinct businesses under the newly formed Catalyst Brands, we had a rare opportunity to reimagine our marketing technology from the ground up," said Marika Bigler, Vice President, Customer Growth and Loyalty at Catalyst Brands. "By consolidating on Attentive, we replaced a complex system with a single, easier-to-manage platform that reduces overhead and enables more personalized customer engagement across every brand." With Attentive, Catalyst Brands is redefining personalized messaging across its portfolio of companies through: * Unified Omnichannel Engagement: Catalyst Brands moved all portfolio brands to Attentive's omnichannel platform for email, push, and SMS, reducing costs while unlocking stronger cross-brand and cross-channel customer engagement opportunities. With a more unified view of each shopper, Catalyst Brands can deliver more personalized messages in the channel most likely to drive engagement. * Agentic AI to Scale Personalized Customer Engagement: Catalyst Brands is leveraging Attentive's agentic AI solutions, including AI Pro and AI Grow, to personalize messaging in real time and convert more visitors into subscribers across its portfolio. Acting on real-time customer signals, Attentive's AI agents determine who to message, what to say, when to send it, and which channel is likely to perform best for all customers across all of Catalyst's portfolio brands. * Mobile-First Identity for Better Customer Experiences: Attentive's mobile-first identity gives Catalyst Brands a more accurate way to recognize customers across devices and interactions, creating a unified view of each customer. By connecting behavioral signals, purchase activity, and customer profiles around a customer's mobile device, Catalyst Brands gains a more detailed understanding of each customer and can deliver more personalized experiences across channels and brands. * Enterprise-Scale Migration: Attentive successfully transitioned customer messages and data points for Catalyst Brands to its unified platform, with the migration managed entirely by Attentive and supported by a dedicated customer success team. "The legacy retail martech model centered around a CRM and stitched together with point solutions is no longer delivering the performance retailers need," said Amit Jhawar, CEO of Attentive. "This outdated model is expensive, complex, and not designed for AI. Catalyst Brands saw an opportunity to reimagine what their martech stack could deliver. By consolidating their stack on Attentive, they're moving beyond fragmented technology to unlock the full potential of AI-powered personalization, driving higher-performing campaigns and greater revenue." About Attentive. Attentive is the omnichannel marketing platform redefining how brands and people connect. Trusted by leading global retail and e-commerce brands and high-growth consumer companies, Attentive's mobile foundation gives marketers a stronger signal for recognizing customers, personalizing messaging, and delivering performance across SMS, email, RCS, and push. Its intelligence layer and agentic AI unify customer profiles and act on real-time data, giving marketers what they need to turn messages into moments that drive action, revenue, and loyalty. About Catalyst Brands. Catalyst Brands ignites America's most beloved retail brands to make fashion accessible to all. Its portfolio features legendary department store JCPenney, as well as iconic specialty retail brands Aéropostale, Brooks Brothers, Lucky Brand, and Nautica. Established in 2025, when JCPenney and the former SPARC Group combined, Catalyst Brands today operates 1,800 retail stores, shop-in-shops, and eCommerce platforms throughout the U.S. and Canada. It also serves leading wholesale accounts in North America and beyond.

Attentive announced the release of new AI Pro and AI reporting functionality.

Attentive announced the release of new AI Pro and AI reporting functionality. Search. Frye reports 13% overall revenue lift with Attentive AI Pro Suite Attentive(R), the omnichannel marketing platform for retailers, apparel brands and e-commerce companies redefining how brands and people connect through relevant, personalized experiences, today announced the next generation of its agentic AI marketing solutions with Lifecycle Intelligence, a new set of capabilities within Attentive AI Pro. Lifecycle Intelligence helps marketers better understand customer behavior, value and product interests throughout their journey, enabling smarter decisions about who to reach and how to engage them. Lifecycle Intelligence includes three new capabilities: * Product Affinity: Now generally available to AI Pro customers, Product Affinity enables marketers to build dynamic audiences around customer interest in specific products and categories. * Recency, Frequency and Monetary Value (RFM): Available to AI Pro customers in beta, RFM provides a clearer picture of how recently and how often customers buy, and how much they spend. * Customer Lifetime Value (LTV): Available to AI Pro customers in beta, Customer LTV allows brands to understand what customers have spent and what they may spend over time, helping marketers determine where to focus retention efforts. Lifecycle Intelligence helps marketers make sense of the countless signals they receive from customers, while Attentive's agentic AI simultaneously acts on signals such as customer interests, behaviors and value to keep audience segments current and campaign delivery highly relevant. "Marketers now have endless data points from their customers and have been begging for an engine that learns from and acts on those signals for years, but the technology just wasn't there until recently," said Eric Miao, Chief Strategy Officer and Chief Product Officer at Attentive. "Attentive AI is helping brands understand their customers and their interests more clearly. That deeper understanding can drive revenue lift while creating stronger, more meaningful relationships over time." How Brands Are Using AI Pro to Drive Measurable Results Brands are already seeing measurable results with Attentive AI Pro. Frye US has embraced the broader AI Pro suite to unlock incremental revenue, with a 13% overall revenue lift. AI Pro also helped Flag & Anthem recognize more shoppers and connect more behavior to real customer profiles, giving the brand more opportunities to trigger relevant messages based on what shoppers were browsing, abandoning, or showing interest in. This led to a 28% lift in additional people identified for follow-up, 7% more incremental sign-ups, and a 20% increase in abandonment journey revenue. "We have so many different customer interests across the brand - golf, western-inspired styles, everyday apparel, women's, and more. There's a big opportunity to segment more thoughtfully and send customers the content they actually want to see," said Beth Tusso, Senior Director of Marketing, Flag & Anthem. Expanding AI Across the Marketing Workflow Attentive is also expanding AI across more of the marketer's workflow with Reporting Agent and Model Context Protocol (MCP) capabilities, both available in beta. Reporting Agent gives marketers a conversational way to ask questions about their Attentive program, quickly understand what changed and why, and surface recommendations for next steps in minutes. MCP enables marketers to securely connect external AI tools like ChatGPT and Claude with Attentive, with over 70 tools currently available in beta to streamline campaign creation, audience building, reporting and more. For brands like Spiraledge, the MCP is already making it faster and easier to get answers about program performance without relying on manual reporting. "If I have a question about our email and SMS program, I can go and answer it myself at whatever depth that I need right now, and I can do this in a few minutes." Adam Hayim, Chief Marketing Officer, Spiraledge.

Attentive announces the launch of AI Grow.

Attentive announces the launch of AI Grow. AI Grow analyses website visitor behaviour in real time to identify the optimal moment to present email and SMS sign-up invitations. Attentive, the omnichannel marketing platform for retailers, apparel brands, and ecommerce companies, has announced the general availability of AI Grow, its AI-driven subscriber list growth product. AI Grow analyses website visitor behaviour in real time to identify the optimal moment to present email and SMS sign-up invitations, helping brands convert more visitors into high-quality subscribers. How AI Grow Optimises Retailers' Subscriber Growth in Real Time Almost every retailer still relies on fixed sign-up rules that treat every website visitor the same. AI Grow instead analyses real-time browsing and shopping behaviour among identified and logged-out visitors to determine the optimal moment to present a sign-up invitation, based on each shopper's likelihood of engagement. AI Grow enhances a brand's existing sign-up experience, using AI to make each interaction more relevant to the individual shopper. It continuously tests and learns from shopper behaviour and performance data to identify and engage visitors more effectively, without requiring marketers to run manual tests while respecting their rules and guidelines. Performance can be tracked directly in the platform or through existing 3rd party analytics tools. "For decades, retailers have relied on a rules-based approach to engage website visitors, even though every shopper makes buying decisions differently," said Eric Miao, Chief Strategy Officer and Chief Product Officer at Attentive. "AI gives us the opportunity to start personalisation earlier - at the moment a shopper decides whether to begin a relationship with a brand. By adapting to each shopper in real time, AI Grow brings that intelligence to the very first interaction, helping marketers turn more of the traffic they already have into valuable, long-term customer relationships." AI Grow Customer Results: Measurable Subscriber and Revenue Growth Every AI Grow deployment is measured through incremental, cohort-level A/B testing against a brand's existing setup, allowing marketers to clearly isolate new subscribers and revenue generated by the product. Brands that tested AI Grow in beta experienced a median increase of approximately 25% in email and SMS sign-ups from existing website traffic and a median 35% increase in welcome series revenue. Yankee Candle saw a 52% combined lift in SMS and email subscribers in its first deployment and, in its most recent steady-state experiment, a 20% lift in welcome conversion across both channels. "It's been super valuable, especially in how we optimise our messaging with timing, targeting, and testing. Ultimately, it [AI Grow] helps us make smarter decisions faster, which is critical for a brand like ours managing a high volume of campaigns across channels," said Deepthy Marunninal, Sr. Manager, CRM at Yankee Candle. "The biggest gains come from how channels really work together. Investing in personalisation early doesn't have to be super complex to be effective, but it does make a significant impact on engagement and performance." Other brands are seeing similar gains with AI Grow. Clove saw a 19% incremental lift in SMS and email subscribers and a 48% increase in welcome revenue, while MANSCAPED captured 2,167 SMS and email opt-ins during its Super Bowl traffic surge - 5.4x its prior-week daily average. AI Grow Feeds Attentive's Agentic AI Platform Ecosystem AI Grow brings Attentive's connected AI experience to the start of the customer journey, helping brands build more personalised relationships from the first interaction. Those visitors and subscribers feed the same identity foundation that powers AI Journeys, which delivers personalised, one-to-one messages to help turn subscribers into customers, and AI Pro, which improves performance across a brand's broader email and SMS marketing program. Together, the products use AI to improve marketers' experience across audience growth, engagement, and campaign performance. AI Grow is now available to Attentive customers and follows the recent launch of Brand Voice 2.0, which helps marketers maintain a consistent brand voice across AI-generated SMS, email, and RCS content. Together, these innovations advance Attentive's broader vision to use AI across the customer journey to make marketing more personalised and effective.
