Company

Noah's Ark makes AI agents accountable.

Agents already decide, order, and pay. We build the record that makes those decisions verifiable, priced, and insurable — from Japan, to the world.

CEO

Kento Tanemura

Founder & CEO

He studied Mathematical Engineering and Information Physics at the School of Engineering, The University of Tokyo, including an exchange at ETH Zürich. As a quantitative researcher at Matsuo Institute, Inc., he developed profitable trading strategies in the Japanese equity market.

To Attract Japan's Top Talents

Work at the frontier, from Tokyo.

Japan's best engineers and researchers should not have to leave to work on frontier problems. We are building the place where they stay — and win globally.

AI-native from day one

No legacy process to unlearn. Agents run the throughput; you own the judgment, the taste, and the hardest problems.

Frontier problems

Zero-knowledge proofs, secure computation, and pricing risk for behaviour with no loss history to price it from — problems where the state of the art is still being written.

Small team, outsized scale

A handful of people operating at the scale of a large organization. Every hire changes the trajectory of the company.

From Japan, to the world

Build from Tokyo for a global market. The ambition is not a domestic niche — it is the accountability layer every autonomous agent runs through.
