Wunderkind launches new Braze integration to turn identity into revenue-driving, orchestrated customer journeys. Wunderkind, the AI decisioning platform that combines identity resolution with cross-channel personalization to increase performance and reach, announced the launch of its latest integration with Braze, the leading customer engagement platform that powers relevant and memorable experiences between consumers and the brands they love. The new integration is designed to help marketers recognize more of their visitors, activate real-time behavioral Signals, and orchestrate high-performing triggered journeys directly within Braze, driving incremental revenue lift from existing traffic and programs. By connecting Wunderkind's identity framework and high-intent behavioral Signals to Braze Canvas, brands can move beyond static campaigns to intelligent, real-time experiences that adapt to customer behavior across web, email and other touchpoints, unlocking net-new revenue that traditional CRM programs leave on the tables. The integration enables marketers to bring triggered and CRM programs together under one roof in Braze, with shared frequency caps, suppression rules, and reporting. "Marketers shouldn't have to choose between performance and simplicity," said Richard Jones, Chief Revenue Officer at Wunderkind. "By bringing Wunderkind's identity graph and high-intent Signals into Braze, we're giving brands a way to recognize more of their shoppers, prioritize their highest-value triggered messages, and run everything inside a single environment their teams already know - without adding another system to manage or rebuilding existing journeys from scratch, and with a clear, measurable lift in triggered and lifecycle revenue." With Wunderkind's integration for Braze, brands can: * Recognize more visitors and expand reach by identifying previously anonymous traffic across sessions, devices, and channels, then turning those visitors into addressable Braze profiles and subscription audiences. * Grow and enrich Braze lists by capturing more email opt-ins on-site and writing new subscribers - along with key attributes and events - directly into Braze in real time. * Scale high-intent triggered journeys by using Wunderkind's Signals to detect meaningful behaviors like product and cart abandonment and pass those signals instantly into Braze Canvas for one-to-one email flows. * Unify CRM and triggered programs by coordinating Wunderkind-powered triggers with existing Braze campaigns, using shared frequency caps, suppression rules, and eligibility logic so triggered sends complement, rather than compete with, batch marketing. * Simplify compliance and mailability by checking subscription and mailability status in Braze before sends, and updating unsubscribe status back into Braze when customers opt out - keeping data aligned across systems. * Maintain operational efficiency with an integration that fits into existing Braze workflows, content, and reporting, minimizing the need for custom engineering while making every message smarter and more timely. Brands leveraging Wunderkind's identity framework have seen up to 8x lift in triggered revenue, and Wunderkind's platform drives more than $5 billion in attributable sales annually across its client base. Brands are already thinking about what this means for their own engagement strategies. "At Kurt Geiger, we're always looking at how our technology partners can work together more effectively. The integration between Wunderkind and Braze is an important development, bringing together capabilities that support a more connected approach to customer engagement," said Gareth Rees-John, Chief Digital Officer at Kurt Geiger.

Dray Jankowski, a laid-off CrowdStrike programme manager, used an AI platform to send 812 job applications in one month after struggling with the traditional job search process. The 30-year-old initially applied to 52 positions manually over three months whilst travelling and hosting a podcast about redundancies. After testing an AI-powered application platform, Jankowski received five serious interview requests aligned with his experience and salary expectations. He progressed with two opportunities and secured an offer within two weeks, landing his current role as senior director of product operations and programme management at Wunderkind. Jankowski credits AI with getting him interviews whilst allowing him to focus on preparation and networking. He notes the job market's increasing reliance on AI screening systems creates challenges for candidates.
WunderKIND Ads, Yahoo DSP expand access to high-intent CTV moments. The integration provides Yahoo DSP buyers with a direct way to access WunderKIND's CTV format through private marketplace deals, using first-party data to deliver non-intrusive ads during high-attention moments on CTV. WunderKIND Ads, the provider of non-interruptive, user-first advertising experiences, has announced a programmatic integration with Yahoo DSP, granting advertisers access to WunderKIND's proprietary CTV Pause Ads. This integration provides Yahoo DSP buyers with a more direct way to access WunderKIND's CTV format through private marketplace deals, using first-party data to deliver non-intrusive ads during high-attention moments on CTV. "Integrating Wunderkind's high-impact display and CTV formats into Yahoo DSP doesn't just expand our inventory; it's an initiative aimed at enhancing user engagement and driving measurable business outcomes," said Beau Ordemann, Vice President, CTV at Yahoo. "By continuously innovating our offerings, we deliver a competitive advantage that unlocks new possibilities for our buyers." By bridging Wunderkind's ad technology with the precision media buying platform of Yahoo DSP, brands can now programmatically activate Pause Ads at scale, targeting known users across premium CTV inventory, triggering engagement during opt-in moments, and measuring full-funnel impact with clarity. Developed in partnership with OpenGlass.TV, Wunderkind's CTV Pause Ad technology ensures seamless delivery and optimisation across platforms. To illustrate the impact of their collaboration, WunderKIND Ads and Yahoo DSP unveiled a highly successful campaign for a luxury retailer seeking to maximise brand impact and engagement among financially discerning, high-value audiences. The strategic campaign successfully combined upper-funnel influence with lower-funnel efficiency, challenging the traditional view of media channels. WunderKIND Ads deployed a sophisticated media mix combining Programmatic CTV Pause Ads on Yahoo DSP with supporting Custom High-Impact display units. The core strategy focused on capturing high-attention moments, during the natural viewing break on CTV and post-content on display. "This campaign proves that non-interruptive advertising is the future of TV and digital media," said Adam Gendelman, Head of Sales and Operations for Wunderkind Ads. "By combining the platform reach of Yahoo DSP with Wunderkind's formats, we've redefined what programmatic CTV can achieve - delivering personalisation, performance, and scale in one move." This approach enables high-value first-party data to be leveraged in formats such as Programmatic CTV Pause Ads, combining precise targeting with distinctive creative execution. "We're thrilled to partner with Wunderkind to measure the performance of their innovative ad formats, which regularly exceed Cint's platform norms, to give our shared clients the confidence and clarity to make informed decisions about their campaigns while they are live," said Laura Manning, SVP, Global Data and Measurement, Cint.
