[Presentation Report] I presented as the operator in the live demo "A Day at a Company" at a co-hosted event with DevRev

Introduction

On August 5, 2026, I appeared as the live demo operator at an event hosted by Classmethod: "Beyond Personal AI — 'DevRev,' the AI That Understands and Works Within Organizations: Founder Keynote & Live Demo." This article reports on the event's content.

About the Event

The event centered on the question of what it takes to move AI from a personal tool to an organizational system.

It was hosted by Classmethod in cooperation with DevRev Japan LLC.

The venue was Classmethod's Hibiya office, with approximately 70 attendees.

On the day, DevRev founder Dheeraj Pandey first introduced the DevRev product in a keynote address.

This was followed by Tetsuo Miyoshi of DevRev Japan, who explained DevRev's knowledge graph in a talk titled "Why Knowledge Graphs Now?"

After that came a 40-minute live demo, followed by a Q&A session and a networking reception.

Structure of the Live Demo

The live demo was handled by myself and Yamamoto from Classmethod, with Yamamoto providing narration and me operating the screen.

Set against the backdrop of a fictional attendance management SaaS company called Midori Cloud Inc., we depicted a day in the life of Takahashi, the customer support manager, in three acts: morning, midday, and evening.

The storyline followed a single inquiry received in the morning, which led through a priority assessment at midday, and by evening had escalated into a situation where a customer with an annual contract worth 12 million yen was considering cancellation. The structure involved showing different screens in each of the three acts, with a final reveal that they had all been looking at the same single piece of data.

How It Felt on the Day

The part of a demo most prone to unpredictable results is when the AI returns a response. The output can vary each time even for the same question, and there is no guarantee the result will be the same in the actual presentation even if stability was confirmed during rehearsal. On the day, the responses came back exactly as intended, which was a relief.

The division of roles also worked as planned. By separating narration from operation, the person speaking could focus on delivery without worrying about the screen's progress, while the person operating could calmly prepare the next screen. I truly felt the advantage of presenting as a pair.

During the Q&A, we received questions that hit directly on the very points we had wanted to convey through the demo. The questions aligned so perfectly with our intentions that it might have looked staged, and it was gratifying to know that our message had reached the audience.

This Was My Third In-Person Presentation

This was my third time presenting at an external event, following JAWS-UG GameTech and AI Innovators Circle. Reports from the previous two are as follows:

• 【Presentation Report】 [JAWS-UG GameTech] 7th GameTech Chapter — Chiba Chapter Collaboration at Odaiba
• 【Presentation Report】 I Spoke as a Developer at DevRev's Panel Discussion "Key Points of Future AI Technology and the Appeal of DevRev"

With each event, I am reminded of the value of seeing the audience's reactions in real time. It is information you cannot get from slides or recordings, and it becomes the basis for deciding what to cover in more depth next time.

Closing

Presenting takes time to prepare, but what you gain exceeds that investment. The gaps in your own understanding become visible the moment you try to explain something to others. And the audience's reaction is something you can only receive by being there in person. If an opportunity to present comes your way, I encourage you to raise your hand.
