Transpose Platform Inc. (headquartered in San Francisco, US, hereafter 'Transpose'), co-hosted by UTokyo IPC, a wholly-owned investment firm of the University of Tokyo, and sponsored by Mori Building Co., Ltd., which develops Roppongi Hills, Toranomon Hills, and Azabudai Hills, held the AI hackathon 'c0mpiled - San Fransokyo' at Toranomon Hills Mori Tower on Sunday, March 8, 2026.
Based on the 7 themes of 'Request for Startups (RFS) Spring 2026', a list of 'areas we want to invest in' published by Y Combinator (YC) for each batch, this event saw members who met on the day conceptualize, develop, and pitch AI products within 4 hours. The event had 272 applicants and 155 participants on the day.
Eleven judges, including 5 YC alumni, evaluated the projects. In addition to a total prize pool of USD 8,000 (approx. 1.2 million JPY), individual office hours with YC Partner Jon Xu were awarded to the top 3 teams.
Furthermore, 6 sponsors, including YC alumni companies, provided over USD 2,600 (approx. 390,000 JPY) worth of tool credits per person to all participants, totaling over USD 403,000 (approx. 60.45 million JPY).
About the 155 participants - CS major students, serial entrepreneurs, startup corporate lawyers developing AI agents, etc.
Of the 155 participants who actually came to the venue, 98 attended seeking to form teams, and 43 wanted to participate solo, but almost everyone, including solo participants, formed teams on the day to tackle development. Each team chose one of the following 7 themes and built a product in 4 hours with members they met for the first time that day.
