Summary

Case study from Zenken, a Japanese digital marketing and recruitment company, on deploying ChatGPT Enterprise to augment a small sales team. Typical enterprise case study format: productivity metrics, use case descriptions (likely content generation, lead qualification, client outreach drafting), and headcount leverage framing.

Implications

Platform thread. The Japan/enterprise thread continues: Zenken joins a growing set of Japanese companies (CyberAgent, others) appearing in OpenAI’s case study library. OpenAI’s Japan strategy relies heavily on enterprise case studies to demonstrate ROI ahead of expanded local data residency. Low standalone signal; part of the enterprise adoption drumbeat.
