Message from Atsuki Momose, Executive Officer & CRO

With the rapid advancement of generative AI, expanded use of data, and evolving legal frameworks, the importance of confidential computing is growing significantly.
Since joining Acompany in April last year, I’ve seen firsthand how the company’s strengths — from business development and legal to R&D and product — work together to drive forward innovation.
Now, as Executive Officer and CRO, I’m fully committed to creating new value through research and development.
The real-world application of deep tech requires a unified approach between R&D and business development. I’ll continue to draw on my experience from both corporate and academic research as I work with our highly skilled team to drive the growth of our confidential computing business.

Message from CEO Ryosuke Takahashi

I’m excited to announce that Atsuki Momose is officially joining the executive team as CRO. He is a top young researcher in confidential computing, with international recognition including back-to-back selection as a program committee member at ACM CCS.
Acompany is a deep tech startup with hardware-based confidential computing at its core. In February, we launched the AutoPrivacy AI CleanRoom to protect data and AI. With Momose’s expertise now part of our leadership, we aim to further accelerate R&D and implementation.
We are committed to achieving discontinuous growth and becoming the world’s leading privacy tech company. Please look forward to the future of Acompany.

What is Hardware-based Confidential Computing?

Confidential computing refers to technology that enables computations to be performed on encrypted data. Among its types, hardware-based confidential computing — often called Trusted Execution Environments (TEEs) — ensures not just confidentiality (data protection), but also integrity, by allowing verification that the code being executed matches the expected, pre-approved version.

In Japan, hardware-based confidential computing has been designated as an essential technology in the Government Cloud initiative. Internationally, it’s already in use by companies like Apple and Google, and has seen adoption by the U.S. Navy and Army, among others — making it a rapidly advancing global technology.
