"AI Marketing Frontline" Event Report: Deep Dive into the AI Agent Era in Marketing

REHATCH Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Ryota Sakoda) held the offline event "AI Marketing Frontline - In-house Marketers Grand Assembly: Super Realistic Case Study Night_Vo3" on Wednesday, May 13, 2026, at Colony#3 in Shimokitazawa, Tokyo. "AI Marketing Frontline" is a closed, offline event exclusively for in-house marketers. Following the first event (February 13, 2026) with ultra-realistic case studies and the second event (March 27, 2026) featuring a themed networking session, this third installment evolved to a format of "two sessions + two table discussions." We received applications from approximately 100 in-house marketers. ■ Background of the Event With the rapid evolution of AI technology, its use in marketing is expanding. However, we often hear comments like, "I don't know how it's actually used on the ground," and "I don't know how to integrate AI into our operations." This event was designed based on the awareness that the approach to AI is shifting from an era of chat to an era of agents. Through two sessions and two table discussions, all participants delved deeply into how to implement a resident agent platform in practical marketing work. ■ Program of the Day 19:00-19:15 Doors Open/Reception 19:15-19:25 Opening (Setting the stage, timeline explanation) 19:25-19:40 Session ① "Beyond Conversational AI: Marketing in the Age of Resident Agents" 19:40-20:00 Table Discussion ① 20:00-20:10 Break & Networking 20:10-20:25 Session ② "Implementing Memory / Skills / Automation in Marketing Practice" + ENSOR Introduction 20:25-20:45 Table Discussion ② 20:45-20:50 Questionnaire 20:50-21:30 Overall Networking & Open Exchange ■ Session ① "Beyond Conversational AI: Marketing in the Age of Resident Agents" Speaker: Gen Yamazaki (COO, REHATCH Inc.) Yamazaki pointed out that the common pitfall for many marketers, "having to explain everything to a chat AI from scratch every time," is a sign of hitting a limit. He explained that AI is evolving from an "answerer" to a "worker (AI worker)," and a resident agent platform with memory, skill acquisition, and automatic execution will revolutionize marketing operations. The session concluded with the message shared throughout the venue: "Leveraging AI in marketing is not about getting one smart answer, but about creating a system that continues to learn." ■ Table Discussion ① Following Session ①, participants deepened their discussion at each table on the following themes: ・"What are the 'weekly repetitive tasks' in your job? How would things change if an Agent were introduced?" ・"In your team, which tasks consistently use AI and which are still manual? What do you think causes this difference?" Numerous "weekly repetitive tasks" such as report creation, creative production, and data aggregation were mentioned across industries, leading to a frank exchange of opinions on the barriers hindering continuous AI adoption. ■ Session ② "Implementing Memory / Skills / Automation in Marketing Practice" Speaker: Seima Matsufuji (REHATCH Inc.) Building on the concept of a "continuously learning system" presented by Yamazaki in Session ①, Matsufuji explained the specific methodology for implementation. He introduced an approach to create reproducibility with a three-layer structure of Memory × Skills × Automation, and argued that "designing it as a system" is the key to escaping dependence on individuals. In the latter half, he introduced "ENSOR," a product that implements these three layers specifically for creative production. ■ Table Discussion ② ・"What is the current system for creative production in your team? What are the bottlenecks?" ・"If a 'creative mass-production Agent' were introduced into your current system, which process do you think would change the most?" Common issues raised at each table included strained designer resources, person-dependent direction, and slow PDCA cycles, which led to discussions on implementation, specifically "where to insert the Agent." ■ Participant Feedback (Average satisfaction: 3.9 out of 5) ・"I was able to clarify the difference between 'chat AI' and 'agent AI,' and it became clear what my company is lacking." ・"The biggest takeaway was hearing about the actual situations at other companies during the table discussion. I was surprised by the commonality of the challenges." ・"The session and discussion were linked, and the design that didn't just end with listening was great." ■ Announcement of Next Event Following this event, we are planning the next installment of the "AI Marketing Frontline" series. Details will be announced at a later date. ■ Event Overview (Actual) Event Name: AI Marketing Frontline - In-house Marketers Grand Assembly: Super Realistic Case Study Night Date: May 13, 2026 (Tue) 19:00-21:30 Venue: Colony#3 Shimokitazawa (2-27-9 Kitazawa, Setagaya-ku, Tokyo) Organizer: REHATCH Inc. 【About ENSOR】 ENSOR is an AI creative generation platform for marketers, based on the concept of "An AI that mass-produces winning banners—a continuously learning marketing OS."
