[Cosinkorea.com | Reporter Gil Tae-yoon] Trendier AI, an AI data solutions company for the beauty industry (co-CEOs Jungwook Son and Kei Chun), proposed the “hybrid team” model—one that embraces AI not merely as a tool but as a core “teammate”—as a new success formula for K-beauty at the Amazon Beauty in Seoul 2025 event held on the 19th.
The event was organized to share strategies for supporting the global expansion of K-beauty brands, with senior executives from Amazon’s beauty divisions across the U.S., Japan, Australia, and South America visiting Korea in person. With more than 1,000 offline attendees and over 5,000 online registrations, the event marked its largest scale to date. Trendier AI drew particular attention as the only invited AI technology partner and speaker.
During the presentation, co-CEO Kei Chun emphasized that AI should be viewed not as a simple automation tool, but as a “core teammate” that actively contributes to performance outcomes. He explained in detail how AI has transformed efficiency across R&D, product planning, and marketing.
In R&D, AI has reduced the time required to predict consumer responses to tens of thousands of ingredient and efficacy combinations—from over a month to just a single day. This has significantly lowered trial-and-error costs and risks in new product development, while dramatically accelerating time to market.
At the product planning stage, AI analyzes hundreds of thousands of consumer reviews in real time to identify previously hard-to-detect “unmet needs.” As a result, market research and new product planning reports that once took more than a month can now be completed in just a few hours.
In marketing, AI trained on competitors’ promotional strategies and consumer response data can instantly propose optimal A/B testing strategies and creative concepts. Campaign preparation timelines that once took weeks are now compressed into daily cycles, enabling far more agile execution.
Chun identified “accurately structured market data” as the key prerequisite for these innovations. “To address AI’s biggest weakness—hallucinations—we must continuously supply verified data in real time,” he explained. “True 10x productivity is only achieved when data and AI are fully integrated.”
He also highlighted the shift in leadership required in the AI era. “If leaders in the past were drill instructors training soldiers, today’s leaders must become commanders directing thousands of AI drone units,” he said. “Without a fundamental shift in perspective, achieving a tenfold increase in productivity is impossible.”
Meanwhile, the event was attended by Amazon’s global senior executives, including Melis Del Rey (Vice President, Beauty & Health), Allie Oosta (Chief Marketing Officer and Vice President of Marketing), and Yuki Suita (Head of Japan Beauty), who shared their expectations for K-beauty’s global potential and Amazon’s support strategies.
Trendier AI stated, “K-beauty companies will gain faster execution capabilities and greater scalability through data and AI-driven automation,” adding that it aims to accelerate the global growth of K-beauty by providing AI automation technologies that support this transformation.
