Tereshee ties 生成AIパスポート to 3–4 hour prep cut

Tereshee's starting point was a familiar one for any company that has switched on generative AI company-wide: access alone did not produce consistent use. Interviews inside the agency surfaced two opposite problems at once. Some employees said they did not know how to use the tools, and some were afraid to try because they could not tell which data was safe to input. Others, by contrast, did not fully recognize the risks that come with AI use. For an ad agency whose service quality tends to depend on the individual account person, that spread of literacy threatened to widen differences in the work clients receive.

The response was to treat the problem as two tracks rather than one. On the people side, Tereshee made the 生成AIパスポート certification mandatory for all full-time employees, giving everyone a common baseline in AI fundamentals and usage risk instead of concentrating knowledge among a few enthusiasts. On the infrastructure side, it gathered internal information into Notion and set up Notion AI to search and analyze that accumulated material in daily work. The two moves are meant to reinforce each other: a shared baseline makes it harder for usage to cluster around a few skilled staff, while a controlled information base addresses the data-leak concern that was keeping some employees from using AI at all.

The reported payoff is operational. Tereshee says meeting preparation time has fallen by 3–4 hours, and that roughly 20 AI agents are now in operation as it pushes further into automating business processes. The case is a reminder that company-wide AI adoption tends to be a knowledge-and-governance problem as much as a tooling decision.
