Voices
Being able to compare numerous IT products at once dramatically improves the efficiency of evaluating solutions for adoption.
As a business-meeting-oriented exhibition, discussions often progress to specific quotes and implementation timelines.
Two staffers toured booths and talks and concluded that spec clarity decides output quality (from Yadokari's report, in Japanese)
Seminars and booths alike showed AI solutions reaching every category (from Kobako's report, in Japanese)
A first-time visitor from CloudNative was stunned by the venue's scale, from security to robotics, and, working fully remote, found it precious to see products and talk to vendors face to face (from CloudNative's report, in Japanese)
forUSERS CEO Takashi Ibata was struck by the line 'in the AI era, keep pursuing' from Anthropic's Claude Code session, and felt the crowd's palpable appetite for AI services across the venue (from Ibata's report, in Japanese)
