For this inaugural event, Daiki Yokota, Editor-in-Chief of Diamond Inc.’s Second Editorial Department and the editor behind numerous business bestsellers, will take the stage. He will be joined by Shohei Onishi, a lawyer highly trusted in the startup community, and Masato Shimohira, co-founder of the venture capital firm ON&BOARD, for a special discussion on “bestsellers in the AI era” and “next-generation input methods through books × AI.” Admission is free, with capacity limited to 100 participants. Background: Startup Finance, Effectuation, Zero Second Thinking, Statistics Is the Strongest Discipline, and many other era-defining bestsellers have been brought to market by Daiki Yokota, Editor-in-Chief of Diamond Inc.’s Second Editorial Department, who has earned deep trust from entrepreneurs and investors.

How will books, a medium packed with vast knowledge, be deconstructed and reconstructed by AI? The session will cover topics ranging from the “new reading experience in the AI era” envisioned by a legendary editor to practical defensive applications that help startups survive.
