Atsuki Momose

I am the founder and CEO of Almure Inc. At Almure, we are building the security foundation to bring the most sensitive data into AI agents, leveraging cutting-edge AI security technologies such as Confidential Computing.

Previsouly, I served as an Executive Officer and Head of Research at Acompany, a privacy-tech startup based in Japan. Prior to that, I was a Research Scholar and Ph.D. student in Computer Science at the University of Illinois Urbana-Champaign.

I am truly grateful to the Ethereum Foundation for supporting my research through a grant. I am honored to have received the Tsujii Shigeo Security Paper Award (2022) and the Illinois Distinguished Fellowship. I also serve as a program committee member for ACM CCS 2024 and ACM CCS 2025.
